Operator settings
The Operator settings page enables you to select which frequency band you will use for your connection and enables you to scan
for available network operators in your area.
Figure 9 - Band settings
Note: In order to change the operator’s band settings, the data connection must be disabled. When you access this page,
you are prompted to disable the data connection if it is already active.
You may want to do this if you’re using the router in a country with multiple frequency networks that may not all support High Speed
Packet Access (HSPA). You can select the router to only connect on the network frequencies that suit your requirements.
Use the Change band drop down list to select the band you wish to use.
The following band settings options are available:
Note: The available bands may vary depending on your variant of the product.
It is not necessary to change the default setting of All bands in most cases. In fact, locking to a particular band can cause
connection difficulties if the device is moved to a location where the forced band selection is no longer available.
When All bands is selected, the router attempts to find the most suitable band based on the available networks for the inserted SIM
card.
The “GSM all” and “WCDMA all” options allow you to force the device to lock to those particular networks only.
Click the Save button to save and apply your selection.
Operator settings
The operator settings feature allows you perform a scan of available networks, and to optionally lock to a particular network
returned by the network scan. To scan for available networks, set the Select operator mode from automatic to Manual then click the
scan button. This operation can take a few minutes and requires that the packet data session be disconnected prior to scanning.

Note: Certain module firmware versions may not allow forbidden operators to be selected.
Select the most appropriate service from the list shown and click Apply.
When Select operator mode is set to Automatic, the router selects the most appropriate operator based on the inserted SIM card.
This is the default option and is sufficient for most users.
SIM security settings
The SIM security settings page can be used for authenticating SIM cards that have been configured with a security PIN.
Unlocking a PIN locked SIM
If the SIM card is locked, you will receive a notice when you access the Status page after which you will be directed to the PIN
settings page to enter the PIN. The PIN settings page lists the status of the SIM at the top of the page.

If you are not redirected to the PIN settings page, to unlock the SIM:
a) Click on the Networking menu from the top menu bar, and then click SIM security settings.
Figure 12 - SIM security settings - SIM PIN locked
b) Enter the PIN in the Current PIN field and then enter it again in the Confirm current PIN field to confirm the PIN.
c) If you are placing the router in a remote, unattended location, you may wish to check the Remember PIN option. This
feature allows the router to automatically send the PIN to the SIM each time the SIM asks for it (usually at power up). This
enables the SIM to be PIN locked (to prevent unauthorised re-use of the SIM elsewhere), while still allowing the router to
connect to the cellular service.
When this feature is enabled, the PIN you enter when setting the Remember PIN feature is encrypted and stored locally on
the router. The next time the SIM asks the router for the PIN, the router decrypts the PIN and automatically sends it to the
SIM without user intervention.
When this feature is disabled and the SIM is PIN locked and the PIN must be manually entered via the router‘s
configuration interface. In situations where the router will be unattended, this is not desirable.
Note: Select Remember PIN if you do not want to enter the PIN code each time the SIM is inserted.

LAN
LAN configuration
The LAN configuration page is used to configure the LAN settings of the n-Hub and to enable or disable DNS Masquerading. LAN
access to the n-Hub is made via the USB interface using a standard USB Type A to Micro USB cable or via WiFi using the same IP
address. To access the LAN configuration page, click on the Networking menu at the top of the screen, then click on the LAN menu
on the left.
Figure 18 – LAN configuration settings
The default IP of the LAN port is 192.168.1.1 with subnet mask 255.255.255.0. To change the IP address or Subnet mask, enter
the new IP Address and/or Subnet mask and click the Save button.
Note: If you change the IP address, remember to reboot the router and enter the new IP address into your browser address
bar.
DNS masquerading
DNS masquerading allows the router to proxy DNS requests from LAN clients to dynamically assigned DNS servers. When enabled,
clients on the router’s LAN can then use the router as a DNS server without needing to know the dynamically assigned cellular
network DNS servers.
With DNS masquerading ON, the DHCP server embedded in the N-Hub hands out its own IP address (e.g. 192.168.1.1) as the
DNS server address to LAN clients. The downstream clients then send DNS requests to the N-Hub which proxies them to the
upstream DNS servers.
With DNS masquerading OFF, the DHCP server hands out the upstream DNS server IP addresses to downstream clients directly,
so that downstream clients send DNS requests directly to the upstream DNS servers without being proxied by the N-Hub.
You may also override the DNS Masquerading option by specifying custom DNS Server IP addresses in the DHCP Server
configuration mentioned in the next section of this guide. In this case the DHCP server assigns downstream devices the manually
configured addresses and the DNS Masquerading option is ignored.
In most cases, it is not necessary to disable DNS masquerading but if you need to, click the DNS masquerading toggle key to turn it
OFF and then click the Save button.

WAN failover
The WAN failover page displays a summary of the configured WAN interfaces and their priorities (Metric). Lower metric values
determine higher priority. The priority of the interfaces can be adjusted using the up and down arrows in the Priority column. When
the interface with the highest priority goes down, the router fails over to the next highest priority interface. The method used to
determine whether an interface is “up” or “down” is defined by the Monitor setting. By default, an interface is monitored by its link
status.
To access the WAN failover page, click on the Networking menu at the top of the screen then click on the WAN failover menu item
on the left.

Routing
Static
Static routing is the alternative to dynamic routing used in more complex network scenarios and is used to facilitate communication
between devices on different networks. Static routing involves configuring the routers in your network with all the information
necessary to allow the packets to be forwarded to the correct destination. If you change the IP address of one of the devices in the
static route, the route will be broken.
To access the Static routing page, click on the Networking menu at the top of the screen, click on the Routing menu on the left,
then click on the Static menu item.
Figure 33 - Static routing list
Some routes are added by default by the router on initialization such as the Ethernet subnet route for routing to a device on the
Ethernet subnet.
Adding Static Routes
To add a new route to the static routing list, click the +Add button. The Static routes page appears.
1. In the Route name field, type a name for the route so that it can be identified in the static routing list.
2. From the Network interface drop down list, select the interface for which you would like to create a static route.
3. In the Destination IP address field, enter the IP address of the destination of the route.
4. In the IP subnet mask field, enter the subnet mask of the route.
5. In the Gateway IP address field, enter the IP address of the gateway that will facilitate the route.

Port forwarding
The Port forwarding list is used to configure the Network Address Translation (NAT) rules currently in effect on the router. To access
the Port forwarding page, click on the Networking menu at the top of the screen, click on the Routing failover menu on the left, then
click on the Port forwarding menu item.
Figure 37 – Port forwarding list
The purpose of the port forwarding feature is to allow mapping of inbound requests to a specific port on the WAN IP address to a
device connected on the Ethernet interface.
Adding a port forwarding rule
To create a new port forwarding rule:
1. Click the +Add button. The port forwarding settings screen is displayed.
2. Use the Protocol drop down list to select the type of protocol you want to use for the rule. The protocols selections
available are TCP, UDP and All.
3. In the Source IP Address field, enter a “friendly” address that is allowed to access the router or a wildcard IP address
(0.0.0.0) that allows all IP addresses to access the router.
4. The Source Port Range (From) and (To) fields are used to specify the port(s) on the source side that are to be forwarded.
This allows you to send a range of consecutive port numbers by entering the first in the range in the (From) field and the
last in the range in the (To) field. To forward a single port, enter the port in the (From) field and repeat it in the (To) field.
5. In the Destination network address field, enter the IP address of the client to which the traffic should be forwarded.
6. The Destination Port Range (From) and (To) fields are used to specify the port(s) on the destination side that are to be
forwarded. If the Source port range specifies a single port then the destination port may be configured to any port. If the
Source port range specifies a range of port numbers then the Destination port range must be the same as the Source port
range.
7. Click the Save button to confirm your settings.

DMZ
The Demilitarized Zone (DMZ) allows you to configure all incoming traffic on all protocols to be forwarded to a selected device
behind the router. This feature can be used to avoid complex port forwarding rules, but it exposes the device to untrusted networks
as there is no filtering of what traffic is allowed and what is denied. The DMZ configuration page is used to specify the IP Address of
the device to use as the DMZ host.
To access the DMZ page, click on the Networking menu at the top of the screen, click on the Routing failover menu on the left, then
click on the DMZ menu item.

Router firewall
The Router firewall page is used to enable or disable the in-built firewall on the router. When enabled, the firewall performs stateful
packet inspection on inbound traffic from the wireless WAN and blocks all unknown services, that is, all services not listed on the
Services configuration page of the router.
With respect to the other Routing options on the Networking page, the firewall takes a low priority. The priority of the firewall can be
described as:
DMZ > MAC/IP/Port filtering rules > MAC/IP/Port filtering default rule > Router firewall rules
In other words, the firewall is of the lowest priority when compared to other manual routing configurations. Therefore, a MAC/IP/Port
filtering rule takes priority in the event that there is a conflict of rules. When DMZ is enabled, MAC/IP/Port filtering rules and the
router firewall are ignored but the router will still honour the configuration of the Remote router access control settings listed under
Administration Settings.
To access the DMZ page, click on the Networking menu at the top of the screen, click on the Routing failover menu on the left, then
click on the Router firewall menu item.

MAC / IP / Port filtering
The MAC/IP/Port filter feature allows you apply a policy to the traffic that passes through the router, both inbound and outbound, so
that network access can be controlled. When the filter is enabled with a default rule of “Accepted”, all connections will be allowed
except those listed in the “Current MAC / IP / Port filtering rules in effect” list. Conversely, when the default rule is set to “Dropped”,
all connections are denied except for those listed in the filtering rules list.
To access the MAC / IP / Port filtering page, click on the Networking menu at the top of the screen, click on the Routing failover
menu on the left, then click on the MAC / IP / Port filtering menu item.
Figure 41 - MAC / IP / Port filtering
Note: When enabling MAC / IP / Port filtering and setting the default rule to “Dropped”, you should ensure that you have
first added a filtering rule which allows at least one known MAC/IP to access the router, otherwise you will not be able to
access the user interface of the router without resetting the router to factory default settings.
Creating a MAC / IP / Port filtering rule
To create a filtering rule:
1. Click the MAC / IP / Port filtering toggle key to switch it to the ON position.
2. Using the Default rule (inbound/forward) drop down list, select the default action for the router to take when traffic reaches
it. By default, this is configured to Accepted. If you change this to Dropped, you should first configure a filter rule that
allows at least one device access to the router, otherwise you will effectively be locked out of the router.
3. Click the Save button to confirm the default rule.
4. In the Current MAC / IP / Port filtering rules in system section, click the +Add button.

DESCRIPTION
Bound
Use the drop down list to select the direction of the traffic for which you want to apply to the rule.
Inbound refers to all traffic that is entering the router including data entering from the WAN and the
LAN. Outbound refers to all traffic exiting the router including traffic leaving in the direction of the
WAN and traffic leaving in the direction of the LAN. Forward specifies traffic that enters on the LAN or
WAN side and is forwarded to the opposite end.
Protocol
Use the drop down list to select the protocol for the rule. You can have the rule apply to All
protocols, TCP, UDP, UDP/TCP or ICMP.
Source MAC Address
Enter the MAC address in six groups of two hexadecimal digits separated by colons (:). e.g.
00:40:F4:CE:FA:1E
Source IP Address
Enter the IPv4 address that the traffic originates from and the subnet mask using CIDR notation.
Destination IP Address
Enter the IPv4 address that the traffic is destined for and the subnet mask using CIDR notation.
Action
Select the action to take for traffic which meets the above criteria. You can choose to Accept or Drop
packets. When the default rule is set to Accept, you cannot create a rule with an Accept action since
the rule is redundant. Likewise, if the default rule is set to Dropped you cannot create a rule with a
Drop action.

There are 5 authentication types you can choose from:
CHAP – uses a three way handshake to authenticate the identity of a client.
MS-CHAP v1 – This is the Microsoft implementation of the Challenge Handshake Authentication Protocol for which
support was dropped in Windows® Vista.
MS-CHAP v2 - This is the Microsoft implementation of the Challenge Handshake Authentication Protocol which was
introduced in Windows® NT 4.0 and is still supported today.
PAP – The Password Authentication Protocol uses a password as a means of authentication and as such, is
commonly supported. PAP is not recommended because it transmits passwords unencrypted and is not secure.
EAP – Extensible Authentication Protocol. An Authentication protocol commonly used in wireless networks.
8. The metric value helps the router to prioritise routes and must be a number between 0 and 65535. The default value is 30
and should not be modified unless you are aware of the effect your changes will have.
9. The Use peer DNS option allows you to select whether the remote clients will use the Domain Name Server of the PPTP
server. Click the toggle key to set this to ON or OFF as required.

The TR-069 (Technical Report 069) protocol is a technical specification also known as CPE WAN Management Protocol (CWMP). It
is a framework for remote management and auto-configuration of end-user devices such as customer-premises equipment (CPE)
and Auto Configuration Servers (ACS). It is particularly efficient in applying configuration updates across networks to multiple CPEs.
TR-069 uses a bi-directional SOAP/HTTP-based protocol based on the application layer protocol and provides several benefits for
the maintenance of a field of CPEs:
Simplifies the initial configuration of a device during installation
Enables easy restoration of service after a factory reset or replacement of a faulty device
Firmware and software version management
Diagnostics and monitoring
Note:
You must have your own compatible ACS infrastructure to use TR-069. In order to access and configure the TR069 settings you must be logged into the router as the root user.
When a factory reset of the router is performed via TR-069, the TR-069 settings are preserved.

occurs, you will need to perform a factory reset in order to restore normal operation.
We highly recommended that you use the white list and a password when utilising this feature to prevent unauthorised
access. See the White list description for more information.

UM-00014 v1.2
Only accept authenticated SMS messages
Enables or disables checking the sender’s phone number against the allowed sender white list for incoming diagnostics and
command execution SMS messages.
If authentication is enabled, the router will check if the sender’s number exists in the white list. If it exists, the router then checks the
password (if configured) in the incoming message against the password in the white list for the corresponding sending number. If
they match, the diagnostic or command is executed.
If the number does not exist in the white list or the password does not match, the router does not execute the incoming diagnostic
or command in the SMS message.
This is enabled by default and it is strongly advised that you leave this feature enabled to maintain security.
Send Set command acknowledgement replies
The N-Hub will automatically reply to certain types of commands received, such as
get
commands, or
execute
commands.
However acknowledgement replies from the N-Hub are optional with
set
commands and the
Wakeup
command. This option
Enables or disables sending an acknowledgment message after execution of a
set
command or SMS Wakeup command. If
disabled, the router does not send any acknowledgement after execution of a
set
command or SMS Wakeup command. All
acknowledgment replies are stored in the Outbox after they have been sent. This can be useful to determine if a command was
received and executed by the router. This option is disabled by default.
Access advanced RDB variables
By default, this option is turned off and only allows access to the basic RDB variables listed later in this guide. If this option is
enabled, you are able to access the full list of RDB variables via SMS.
Allow execution of advanced commands
By default, this option is turned off and only allows execution of the basic commands listed later in this guide. If this option is
enabled, you are able to execute advanced commands such as those which are common to the Linux command line. For example:
“execute ls /usr/bin/sms*” to list the contents of the /etc folder on the router.
Send acknowledgement replies to
This option allows you to specify where to send acknowledgment messages after the execution of a
set, get, or exec
command.
If a fixed number is selected, the acknowledgement message will be sent to the number defined in the Fixed number to send replies
to field. If the sender’s number is selected, the acknowledgement message will be sent to the number that the SMS diagnostic or
command message originated from. The default setting is to use the sender’s number.
Fixed number to send replies to
This field defines the destination number to which error messages are sent after the execution of a
get, set, or exec
command. This
field is only displayed when Send Error SMS to is set to Fixed Number.
Send command error replies
Enables or disables the sending of an error message resulting from the execution of a
get, set
, or
exec
command. All error replies
are stored in the Outbox after they have been sent.
Send error replies to
When Send Error SMS for Get/Set/Exec Command is set to ON, this option is used to specify where the error SMS is sent. Use the
radio buttons to select either Fixed Number or SMS Sender Number. When set to SMS Sender Number the router will reply to the
originating number of the SMS diagnostic or command. When set to Fixed Number the router will send the error messages to the
number specified in the following field.
Send a maximum number of
You can set the maximum number of acknowledgement and error messages sent when an SMS diagnostic or command is
executed. The maximum limit can be set per hour, day, week or month. The router will send a maximum of 100 replies by default.
The number of messages sent is shown below the options. The total transmitted message count resets after a reboot or at the
beginning of the time frame specified.

White List for diagnostic or execution SMS
The white list is a list of mobile numbers that you can create which are considered “friendly” to the router. If Only accept
authenticated SMS messages is enabled in the diagnostics section, the router will compare the mobile number of all incoming
diagnostic and command messages against this white list to determine whether the diagnostic or command should be executed.
You may optionally configure a password for each number to give an additional level of security. When a password is specified for a
number, the SMS diagnostic or command message is parsed for the password and will only be executed if the number and
password match.
Figure 74 - White list for diagnostic or execution SMS
A maximum of 20 numbers can be stored on the router in the white list. To add a number to the white list, click the “+Add” button.
Figure 75 – Adding a number to the SMS white list
The White List numbers and passwords can be cleared by pressing the button to the right of each entry. To add a number to
the white list, enter it in the Destination number field and optionally define a password in the Password field. When you have finished
adding numbers click the Save button to save the entries.

Sending an SMS Diagnostic Command
Follow the steps below to configure the router to optionally accept SMS diagnostic commands only from authenticated senders and
learn how to send SMS diagnostic commands to the router.
1. Navigate to the Services > SMS messaging > Diagnostics page
2. Confirm that the Enable remote diagnostics and command execution toggle key is set to the ON position. If it is set to OFF
click the toggle key to switch it to the ON position.
3. If you wish to have the router only accept commands from authenticated senders, ensure that Only accept authenticated
SMS messages is set to the ON position. In the White list for diagnostic or execution SMS messages section, click the
+Add button and enter the sender’s number in international format into the Destination number field that appears. If you
wish to also configure a password, enter the password in the Password field corresponding to the destination number.
4. If you would prefer to accept SMS diagnostic commands from any sender, set the Only accept authenticated SMS
messages toggle key to the OFF position.
Note: An alternative method of adding a number to the white list is to send an SMS message to the router, navigate to
Services > SMS messaging > Inbox and then click the button next to the message which corresponds to the sender’s
number.
5. Click the Save button.
Types of SMS diagnostic commands
There are three types of commands that can be sent; execute, get and set. The basic syntax is as follows:
execute COMMAND
get VARIABLE
set VARIABLE=VALUE
If authentication is enabled, each command must be preceded by the password:
PASSWORD execute COMMAND
PASSWORD get VARIABLE
PASSWORD set VARIABLE=VALUE
The following are some examples of SMS diagnostic commands:
password6657 execute reboot
get rssi
set apn1=testAPNvalue
SMS acknowledgment replies
The router automatically replies to get commands with a value and execute commands with either a success or error response. Set
commands will only be responded to if the Send Set command acknowledgement replies toggle key is set to ON. If the Send
command error replies toggle key is set to ON, the router will send a reply if the command is correct but a variable or value is
incorrect, for example, due to misspelling.

Generic Format for writing to variables:
set VARIABLE=VALUE
PASSWORD set VARIABLE=VALUE
Generic Format for executing a command:
Execute COMMAND
PASSWORD execute COMMAND
Replies
Upon receipt of a successfully formatted, authenticated (if required) command, the gateway will reply to the SMS in the following
format:
TYPE
SMS CONTENTS
NOTES
get command
“VARIABLE=VALUE”
set command
“Successfully set VARIABLE to VALUE”
Only sent if the acknowledgment message
function is enabled
execute command
“Successfully executed command COMMAND”
Table 24 - SMS Diagnostic Command Syntax
Where “VARIABLE” is the name of the value to be read
Where “VARIABLE (x)” is the name of another value to be read
Where “VALUE” is the content to be written to the “VARIABLE”
Where “COMMAND” is a supported command to be executed by the device (e.g. reboot)
Where “PASSWORD” is the password (if configured) for the corresponding sender number specified in the White List
Multiple commands can be sent in the same message, if separated by a semicolon.
For Example:
get VARIABLE1; get VARIABLE2; get VARIABLE3
PASSWORD get VARIABLE1; get VARIABLE2
set VARIABLE=VALUE1 ; set VARIABLE2=VALUE2
PASSWORD set VARIABLE1=VALUE1; set VARIABLE2=VALUE2; set VARIABLE3=VALUE3
If required, values can also be bound by an apostrophe, double apostrophe or back tick.
For Example:
“set VARIABLE=’VALUE’”
“set VARIABLE=”VALUE””
“set VARIABLE=`VALUE`”
“get VARIABLE”

UM-00014 v1.2
A password (if required), only needs to be specified once per SMS, but can be prefixed to each command if desired.
“PASSWORD get Variable1”; “get VARIABLE2”
“PASSWORD set VARIABLE1=VALUE1”; “set VARIABLE2=VALUE2”
If the command sent includes the “reboot” command and has already passed the white list password check, the device keeps this
password and executes the remaining command line after the reboot with this same password.
For Example:
“PASSWORD execute reboot; getVariable1”; “get VARABLE2”
“PASSWORD execute reboot; PASSWORD get Variable1”; “get VARABLE2”
Note: Commands, variables and values are case sensitive.
List of basic commands
A list of basic commands which can be used in conjunction with the execute command are listed below:
“pdpcycle”, “pdpdown” and “pdpup” commands can have a profile number suffix ‘x’ added. Without the suffix specified, the
command operates against the default profile configured on the profile list page of the Web-UI.
#
COMMAND NAME
DESCRIPTION
1
reboot
Immediately performs a soft reboot.
2
pdpcycle
Disconnects (if connected) and reconnects the data connection. If a profile number is selected in the
command, try to disconnect/reconnect the specified profile in case the profile is active. If no profile
number is selected, try to disconnect/reconnect the current active profile. Reports an error if no profile
number is selected and there is no currently activated profile.
3
pdpdown
Disconnects the PDP. If a profile number is selected in the command, the router tries to disconnect the
specified profile in case the profile is active. If no profile number is selected, try to disconnect the current
active profile. Reports an error if no profile number is selected and there is no currently activated profile.
4
pdpup
Reconnects the PDP. If a profile number is selected in the command, the router tries to connect with
the specified profile. If no profile number is selected, the router tries to connect to the last active profile.
The gateway will check the currently activated profile and disconnect this profile before executing the
command. The router reports an error if no profile number is selected and there is no stored last active
profile number.
5
factorydefaults
Performs a factory reset on the router. Be aware that this command also clears the SMS white list on
the router.
6
download
Performs a download and install of a Firmware Upgrade (.cdi), Config File (.tar.gz) or a help document
(.pdf) file.
If the file is a firmware image as in the case of a .cdi file, the router will apply the recovery image first and
then the main firmware image. The download location is specified immediately after the command and
may be from an HTTP or FTP source URL.
If the file is a .cdi file, the router will apply the file as a configuration file update for the device and reboot
afterwards.
If the file is a .pdf, the router will assume this is a user guide document and save it to the router and
make the file available for viewing via the help menu on the Web-UI.
Note: If your download URL includes any space characters, please encode these prior to transmission
according to RFC1738, for example:
ftp://username:password@serveraddress/directory%20with%20spaces/filename.cdi
Note: Authenticated FTP addresses may be used following the format as defined in RFC1738, for
example:
ftp://username:password@serveraddress/directory/filename.cdi
7
codconnect
Causes the router to activate the PDP context when the Connect on demand feature is enabled.
8
coddisconnect
Causes the router to de-activate the PDP context when the Connect on demand feature is enabled.
9
wakeup
This forces the default Data connection profile to connect if it is in a disconnected or waiting state.
There are two circumstances in which this command may be useful; where the default profile is enabled
but has been manually disconnected and if Connect on demand is enabled and the router is awaiting
packet of interest. In both of these situations, the wakeup command will cause the default PDP context
to activate.
10
ssh.genkeys
Instructs the router to generate new public SSH keys.
11
ssh.clearkeys
Instructs the router to clear the client public SSH key files.

Table 29 - Operator status codes returned by get plmnscan SMS command
Notes about the network connection status when using the get plmnscan command:
If the connection status is Up and connection mode is Always on, the get plmnscan SMS will cause the connection to
disconnect, perform the scan, send the result through SMS and then bring the connection back up again. If the
connection status is Down, the router will perform the PLMN scan, send the result and keep the connection status down.
If the connection status is Waiting and connection mode is Connect on demand, the get plmnscan SMS will change the
connection status to Down, perform the scan, send the result through SMS and then restore the connection status to the
Waiting state.
If the connection status is Up and connection mode is Connect on demand, the get plmnscan SMS will cause the
connection to disconnect, perform the scan, send the result through SMS, and then restore the connection status to the
Waiting state unless there is a traffic which triggers a connection in which case the connection status will be set to Up.
Setting the router to connect to a network
The router can be instructed by SMS to connect to one of the networks returned by the get plmnscan command. The set forceplmn
command forces the router to connect to a specified operator network (if available) while the get forceplmn command retrieves the
currently configured network on the router.
Command format:
set forceplmn=0|MCC,MNC| MCC,MNC,Network Type
Page 91
www.netcommwireless.com
NetComm Wireless n-Hub
91
UM-00014 v1.2
For example:
set forceplmn=0
Sets the selection of operator and network type to automatic mode.
set forceplmn=505,3
Sets the operator to a manual selection made by the user where “505” is the Mobile Country Code for Australia and “3” is
the Mobile Network Code for Vodafone. As no network type (e.g. LTE/3G/2G) is specified, it is selected automatically.
set forceplmn=505,3,7
Sets the operator and network type to a manual selection made by the user where “505” is the Mobile Country Code for
Australia, “3” is the Mobile Network Code for Vodafone and “7” is the 3G network type.
Notes about the set forceplmn command:
1. If the manual selection fails, the device will fall back to the previous ‘good’ network.
2. When enabled, the SMS acknowledgement reply reflects the success or failure of the manual selection with respect to
the
set
command and includes the final MNC/MCC that was configured.
Confirming the currently configured operator and network type
You can retrieve the currently configured operator and network type using the get forceplmn command.
The get forceplmn command returns the operator and network type selection mode (Automatic/Manual), in addition to the MCC
and MNC values, for example:
Automatic,505,3
This response indicates that the operator/network selection mode is Automatic, and the network used is Vodafone AU.

System
Log
The Log pages are used to display or download the System log and IPSec logs on the router.
System log
The System Log enables you to troubleshoot any issues you may be experiencing with your N-Hub. To access the System Log
page, click on the System menu. The System Log is displayed.
Figure 76 - System log file
Log file
Use the Display level drop-down list to select a message level to be displayed. The message levels are described in the table below.
To download the System log for offline viewing, right-click the Download button and choose Save as.. to save the file. To clear the
System log, click the Clear button. The downloaded log file is in Linux text format with carriage return (CR) only at the end of a line,
therefore in order to be displayed correctly with new lines shown, it is recommended to use a text file viewer which displays this
format correctly (e.g. Notepad++).

IPSec log
The IPSec log section provides the ability for you to download the log for the IPSec VPN function. This can assist in troubleshooting
any problems you may have with the IPSec VPN. To access the IPSec log page, click on the System menu item then select the Log
menu on the left and finally select IPSec log beneath it.
Figure 77 - IPSec log
Use the Log level drop down list to specify the type of detail you want to capture in the log and then click the Save button. When
you change the logging level, any active IPSec VPN tunnels will be disconnected as a change in logging level requires the IPSec
service to be restarted.
To download the IPSec log, click the Download IPSec log button and you will be prompted to save the file.

System log settings
To access the System log settings page, click on the System menu item then select the Log menu on the left and finally select
System log settings beneath it.
Log data is stored in RAM and therefore, when the unit loses power or is rebooted, it will lose any log information stored in RAM. To
ensure that log information is accessible between reboots of the router there are two options:
1. Enable the Log to non-volatile memory option
2. Use a remote syslog server
Figure 78 - System log settings
Non-volatile log
When the router is configured to log to non-volatile memory, the log data is stored in flash memory, making it accessible after a
reboot of the router. Up to 512kb of log data will be stored before it is overwritten by new log data. Flash memory has a finite
number of program-erase operations that it may perform to the blocks of memory. While this number of program-erase operations
is quite large, we recommend that you do not enable this option for anything other than debugging to avoid excessive wear on the
memory.
Log capture level
The log capture level defines the amount of detail that the system log stores. This setting also affects the Display level setting on the
System log page, for example, if this is set to a low level, such as “Error”, the System log will not be able to display higher log levels.
Remote syslog server
The router can be configured to output log data to a remote syslog server. This is an application running on a remote computer
which accepts and displays the log data. Most syslog servers can also save the log data to a file on the computer on which it is
running allowing you to ensure that no log data is lost between reboots.
To configure the N-Hub to output log data to a remote syslog server:
1. Click on the System menu from the top menu bar. The System log item is displayed.
2. Under the Remote syslog server section, enter the IP address or hostname of the syslog server in the IP / Hostname
[PORT] field. You can also specify the port number after the IP or hostname by entering a semi-colon and then the port
number e.g. 192.168.1.102:514. If you do not specify a port number, the router will use the default UDP port 514.
3. Click the Save button to save the configuration.

System configuration
Settings backup and restore
The settings backup and restore page is used to backup or restore the router’s configuration or to reset it to factory defaults. In
order to view the settings page you must be logged into the web user interface as root using the password admin. The backup /
restore functions can be used to easily configure a large number of N-Hub by configuring one router with your desired settings,
backing them up to a file and then restoring that file to multiple N-Hubs.
To access the Settings backup and restore page, click on the System menu item then select the System confguration menu on the
left and finally select Settings backup and restore beneath it.
Figure 80 – Settings backup and restore
Back up your router’s configuration
Log in to the web configuration interface, click on the System menu and select Settings backup and restore.
If you want to password protect your backup configuration files, enter your password in the fields under Save a copy of current
settings and click on Save. If you don’t want to password protect your files, just click on Save. The router will then prompt you to
select a location to save the settings file.
Note: The following conditions apply:-
It is NOT possible to edit the contents of the file downloaded; if you modify the contents of the configuration file in any way
you will not be able to restore it later.
You may change the name of the file if you wish but the filename extension must remain as “.cfg”
Restore your backup configuration
1. In the web configuration interface click on the System menu and select Settings backup and restore.
2. From the Restore saved settings section, click on Browse or Choose a file and select the backup configuration file on your
computer.
3. Click Restore to copy the settings to the new n-Hub. The router will apply these settings and inform you it will reboot -
click on OK.
Restoring the router’s factory default configuration
Click the Restore defaults button to restore the factory default configuration. The router asks you to confirm that you wish to restore
factory default settings. If you wish to continue with the restoring of factory defaults, click OK.
Note: All current settings on the router will be lost when performing a restore of factory default settings. The device IP
address will change to 192.168.1.1 and the default username
root
and default password
admin
will be configured.
