This chapter describes:
Main features
Appearance
1.1 Overview
IP-COM Multi-WAN Hotspot Router M50 is designed for small- and medium-sized enterprises to implement
intelligent network access and management. It offers an AP management system and a multi-authentication
management system, and supports various enterprise-oriented functions including filter management, smart
bandwidth management, PPTP/L2TP/IPSec VPN, and multi-WAN.
1.2 Main features
AP management system
The router is embedded with an AP management system, which is applicable to all IP-COM AP models and can
manage up to 16 APs at the same time. Using the system, you can customize SSIDs, power, channels, user capacity,
reboot policies, and alarm policies for APs.
Multi-authentication management system
The router is embedded with a multi-authentication management system, which supports web authentication,
and PPPoE authentication. This system authenticates, without an additional authentication server, users who
request internet access, which helps reduce enterprise costs.
Web authentication: a portal-based authentication mode, which allows you to add advertisements to the
push page.
PPPoE authentication: a PPPoE server–based authentication mode, which allows users to be authenticated
with PPPoE accounts. This mode enables you to control traffic by account to effectively address network
congestion at peak hours.
Smart bandwidth management
This router supports smart bandwidth control and user-defined bandwidth control.
Smart bandwidth control: You can specify only the actual access bandwidth and leave the router to manage
bandwidth based on bandwidth usage. That is, when the traffic is light, the router allows users to use
excessive bandwidth; when the traffic is heavy, the router strictly controls bandwidth usage.
User-defined bandwidth control: You must specify the upper bandwidth limit per accessing equipment and
the router controls bandwidth usage accordingly.
Filter management
You can configure URL-related filter management policies and application-related filter management policies by IP
address group or time group.

If a state not specified here appears, take measures based on the message corresponding to
the state.
4.2 Setting WAN port parameters
If you have set internet connection parameters but your computer cannot access the internet, try modifying WAN
port parameters.
To access the page for modifying WAN port parameters, choose Network > WAN Parameters. See the following
figure.
4.2.1 WAN speed
If you have correctly connected an Ethernet cable to a WAN port of the router but the Link indicator of the WAN
port does not turn on or it takes over 5 seconds for the Link indicator to turn on after the cable is connected, you
can try resolving the problem by changing WAN Speed of the port to 10M half duplex or 10M full duplex.
Otherwise, it is recommended that you retain the default setting Auto of WAN Speed.
4.2.2 MTU
Maximum Transmission Unit (MTU) indicates the maximum size of a packet that can be transmitted by a network
device. If Connection Type is set to PPPoE, the default MTU value is 1492. If Connection Type is set to Dynamic IP
or Static IP, the default MTU value is 1500. In normal cases, the default values are recommended. If you
encounter any of the following problems, try gradually reducing the value (recommended range: 1400 to 1500) to

MTU Value
Usage
1500
It is the most common value for non-PPPoE connections and non-VPN connections.
1492
It is used for PPPoE connections.
1472
It is the maximum value for the pinging function. (If a greater value is used, packets are
splitted.)
1468
It is used for DHCP, which assigns dynamic IP addresses.
1436
It is used for VPNs or PPTP.
find the suitable value that does not lead to the problem:
Some websites are not accessible or some secure websites cannot be displayed properly (such as the login
pages of online banking websites and Alipay’s website).
Emails cannot be received or servers such as FTP and POP servers are not accessible.
4.2.3 MAC address
If your ISP has bound your internet account with the MAC address (physical address) of your computer, the router
cannot access the internet despite internet connection parameters have been set on the router. In this case, only
the computer can use the account to access the internet. The computer refers to the one used to verify your
internet accessibility after your ISP creates the account for you.
You can try MAC address cloning method 1 or 2 described in the following section to resolve the problem.
Method 1:
1. Connect the computer to the router.
2. Log in to the router web UI on the computer.
3. Choose Network > WAN Parameters.
4. Set MAC Address corresponding to the WAN port used to access the internet to Clone Local Host’s MAC.
5. Click OK.
Method 2:
1. Connect a computer other than the above-mentioned computer to the router.
2. Log in to the router web UI on the computer.
3. Choose Network > WAN Parameters.
4. Set MAC Address corresponding to the WAN port used to access the internet to Custom.

5. Enter the MAC address of the computer with internet accessibility.
6. Click OK.
To restore the default MAC address of the WAN port, choose Network > WAN Parameters, set MAC Address
corresponding to the WAN port to Default MAC, and click OK.
4.3 Setting up your LAN
Choose Network > LAN Setup. On the page that appears, you can set the LAN IP address and DHCP server
parameters for the router.
- 17 -
Network
Parameter
Description
DHCP Server
It is used to enable or disable the DHCP function of the router.
4.3.1 LAN port IP addresses
The LAN IP address is set for the router to communicate within your LAN and for you to manage the router. The
default LAN IP address and subnet mask of the router are 192.168.0.252 and 255.255.255.0 respectively.
Generally, you do not need to change the LAN IP address, unless it is in conflict with another IP address. For
example, the WAN IP address and LAN IP address of the router may be in the same network segment or the
default IP address 192.168.0.252 has been assigned to a device on the LAN.
After the LAN IP address is changed, the message shown in the following figure appears.
When the progress bar is complete, the login page appears. If the page does not appear, verify that the Obtain an
IP address automatically option is selected for the local connection of your computer and an IP address is
assigned from the router to your computer. Then, try accessing the login page with the new LAN IP address.
Note
If the new and old LAN IP addresses belong to different network segments, the router changes the DHCP address
pool accordingly so that the IP addresses in the pool belong to the same network segment as the new LAN IP
address.
4.3.2 DHCP server
The DHCP server automatically assigns IP addresses, subnet masks, gateway IP addresses, and DNS IP addresses to
computers on your LAN. If you disable the DHCP function, you need to manually configure this information on the
computers so that the computers can access the internet. Disable this function only when necessary.
The following table describes the parameters.
- 18 -
Network
Parameter
Description
Start IP
It specifies the start IP address of the DHCP address pool (range of IP addresses that can be
assigned by the DHCP server). The default value is 192.168.0.100.
End IP
It specifies the end IP address of the DHCP address pool. The default value is 192.168.0.200.
Note
The start and end IP addresses must belong to the same network segment as the LAN IP
address of the router.
Lease Time
It specifies the validity of an IP address assigned by the DHCP server to a computer. When
the IP address expires:
If the computer is connected to the router, the computer automatically updates the
lease time to continue using the IP address.
If the computer is not connected to the router (for example, the computer is shut
down or the wired or wireless connection of the computer is released), the router
releases the IP address. Then, when another computer requests an IP address, the
router can assign the released IP address to the computer.
Change the default settings only when necessary.
Primary DNS
It specifies the primary DNS IP address that the DHCP server assigned to computers on your
LAN. The router can function as a DNS proxy. Therefore, the LAN IP address of the router is
set as the primary DNS IP address by default.
Note
Generally, the default value is recommended. If you need to change the value ensure that
the new value is the IP address of a correct DNS server or DNS proxy, so that the computers
on your LAN can access the internet properly.
Secondary DNS
It specifies the secondary DNS IP address assigned by the DHCP server to computers on
your LAN. If the value is blank, the DHCP server does not assign the IP address.
4.3.3 Static IP addresses assignment using DHCP
The filter management, flow control, and virtual server functions of the router are implemented based on IP
addresses assigned to computers. These functions fail when the IP addresses change and as a result you need to
update rules for the functions accordingly.
The function of static IP address assignment using DHCP helps address this problem. It allows the DHCP server to
assign a fixed IP address to a computer, enabling the filter management, flow control, and virtual server functions
to work properly.

3. To delete multiple rules at the same time, select them and click .
4.3.4 DHCP Client List
If the DHCP server function of the router is enabled, you can refer to the DHCP client list for details (including IP
addresses, MAC addresses, and host names) of the clients that obtain IP addresses from the DHCP server.
In addition, you can quickly bind clients with their current IP addresses so that the DHCP server always assigns the
IP addreses to the clients.
Binding a client
1. Choose Network > LAN Setup.
2. Click corresponding to the client to the bound in the DHCP Client Lists area.
The client is bound with its current IP address.
