Erasing the Configuration
It is sometimes desirable to restore the router to a known blank condition. This can be done by
using the Erase function, which will restore all factory settings. After an erase, the router's
password will be password, the LAN IP address will be 192.168.0.1, and the router's DHCP client
will be enabled.
To erase the configuration, click the Erase button.
To restore the factory default configuration settings without knowing the login password or IP
address, you must use the Default Reset button on the rear panel of the router. See “Restoring the
Default Configuration and Password” on page 8-7.
Upgrading the Router Software
Note: Before upgrading the router software, use the router backup utility to save your
configuration settings. Any router upgrade will revert the router settings back to the
factory defaults. After completing the upgrade, you can restore your settings from the
backup.
The routing software of the MR814 v3 router is stored in FLASH memory, and can be upgraded as
new software is released by NETGEAR. Upgrade files can be downloaded from Netgear's Web
site. If the upgrade file is compressed (.ZIP file), you must first extract the binary (.BIN) file
before sending it to the router. The upgrade file can be sent to the router using your browser.
Note: The Web browser used to upload new firmware into the MR814 v3 router must support
HTTP uploads. NETGEAR recommends using Microsoft Internet Explorer or Netscape Navigator
3.0 or above.

interrupted, it may corrupt the software. When the upload is complete, your router will
automatically restart. The upgrade process will typically take about one minute.
In some cases, you may need to reconfigure the router after upgrading.
Changing the Administrator Password
Note: Before changing the router password, use the router backup utility to save your
configuration settings. If after changing the password, you forget the new password you
assigned, you will have to reset the router back to the factory defaults to be able to log in
using the default password of password. This means you will have to restore all the
router configuration settings. If you ever have to reset the router back to the factory
defaults, you can restore your settings from the backup.

Advanced Configuration of the Router
This chapter describes how to configure the advanced features of your MR814 v3 Cable/DSL
Wireless Router. These features can be found under the Advanced heading in the Main Menu of
the browser interface.
Configuring for Port Forwarding to Local Servers
Although the router causes your entire local network to appear as a single machine to the Internet,
you can make a local server (for example, a web server or game server) visible and available to the
Internet. This is done using the Port Forwarding menu. From the Main Menu of the browser
interface, under Advanced, click on Port Forwarding to view the port forwarding menu, shown
below.
Figure 7-1: Port Forwarding Menu
.
Note: If you are unfamiliar with networking and routing, refer to Appendix B,
“Network, Routing, Firewall, and Basics,” to become more familiar with the terms and
procedures used in this manual.
Advanced Configuration of the Router 7-1
202-10039-01
Reference Manual for the MR814 v3 Cable/D SL Wir ele ss Ro ute r
Use the Port Forwarding menu to configure the router to forward incoming protocols to computers
on your local network. In addition to servers for specific applications, you can also specify a
Default DMZ Server to which all other incoming protocols are forwarded. The DMZ Server is
configured in the Security Menu.
Before starting, you'll need to determine which type of service, application or game you'll provide
and the IP address of the computer that will provide each service. Be sure the computer’s IP
address never changes. To configure port forwarding to a local server:
Note: To assure that the same computer always has the same IP address, use the reserved
IP address feature of your MR814 v3 router. See “Using Address Reservation“ on page
7-8 for instructions on how to use reserved IP addresses.
1. From the Service & Game box, select the service or game that you will host on your network.
If the service does not appear in the list, refer to the following section, “Adding a Custom
Service”.
2. Enter the IP address of the local server in the corresponding Server IP Address box.
3. Click the Add button.
Adding a Custom Service
To define a service, game or application that does not appear in the Services & Games list, you
must determine what port numbers are used by the service. For this information, you may need to
contact the manufacturer of the program that you wish to use. When you have the port number
information, follow these steps:
1. Click the Add Custom Service button.
2. Enter the first port number in an unused Start Port box.
3. To forward only one port, enter it again in the End Port box. To specify a range of ports, enter
the last port to be forwarded in the End Port box.
4. Enter the IP address of the local server in the corresponding Server IP Address box.
5. Type a name for the service.
6. Click Apply at the bottom of the menu.

Editing or Deleting a Port Forwarding Entry
To edit or delete a Port Forwarding entry, follow these steps.
1. In the table, select the button next to the service name.
2. Click Edit or Delete.
Local Web and FTP Server Example
If a local PC with a private IP address of 192.168.0.33 acts as a Web and FTP server , conf igure the
Ports menu to forward HTTP (port 80) and FTP (port 21) to local address 192.168.0.33
In order for a remote user to access this server from the Internet, the remote user must know the IP
address that has been assigned by your ISP. If this address is 172.16.1.23, for example, an Internet
user can access your Web server by directing the browser to http://172.16.1.23. The assigned IP
address can be found in the Maintenance Status Menu, where it is shown as the WAN IP Address.
Some considerations for this application are:
• If your account’s IP address is assigned dynamically by your ISP, the IP address may change
periodically as the DHCP lease expires.
• If the IP address of the local PC is assigned by DHCP, it may change when the PC is rebooted.
To avoid this, you can manually configure the PC to use a fixed address.
• Local PCs must access the local server using the PCs’ local LAN address (192.168.0.33 in this
example). Attempts by local PCs to access the server using the external IP address
(172.16.1.23 in this example) will fail.
Multiple Computers for Half Life, KALI or Quake III Example
To set up an additional computer to play Half Life, KALI or Quake III:
1. Click the button of an unused port in the table.
2. Select the game again from the Services/Games list.
3. Change the beginning port number in the Start Port box.
For these games, use the supplied number in the default listing and add +1 for each additional
computer. For example, if you've already configured one computer to play Hexen II (using
port 26900), the second computer's port number would be 26901, and the third computer
would be 26902.

5. Type the IP address of the additional computer in the Server IP Address box.
6. Click Apply.
Some online games and videoconferencing applications are incompatible with NAT. The MR814
v3 router is programmed to recognize some of these applications and to work properly with them,
but there are other applications that may not function well. In some cases, one local PC can run the
application properly if that PC’s IP address is entered as the default in the PORTS Menu. If one
local PC acts as a game or videoconferencing host, enter its IP address as the default.
Configuring the WAN Setup Options
The WAN Setup options let you configure a DMZ server, change the MTU size and enable the
router to respond to a Ping on the WAN port. These options are discussed below.
Setting Up a Default DMZ Server
The default DMZ server feature is helpful when using some online games and videoconferencin g
applications that are incompatible with NAT . The router is programmed to recognize some of these
applications and to work properly with them, but there are other applications that may not function
well. In some cases, one local PC can run the application properly if that PC’s IP address is entered
as the default DMZ server.
Note: DMZ servers pose a security risk. A computer designated as the default DMZ
server loses much of the protection of the firewall, and is exposed to exploits from the
Internet. If compromised, the DMZ server can be used to attack your network.
Incoming traffic from the Internet is normally discarded by the router unless the traffic is a
response to one of your local computers or a service that you have configured in the Ports menu.
Instead of discarding this traffic, you can have it forwarded to one computer on your network. This
computer is called the Default DMZ Server.
7-4 Advanced Configuration of the Router
202-10039-01
Reference Manual for the MR814 v3 Cable/DSL Wireless Router
The WAN Setup menu, shown below lets you configure a Default DMZ Server.
Figure 7-2: WAN Setup menu.
To assign a computer or server to be a Default DMZ server, follow these steps:
1. Click WAN Setup link on the Advanced section of the main menu.
2. Type the IP address for that server. To remove the default DMZ server, replace the IP address
numbers with all zeros.
3. Click Apply.
Respond to Ping on Internet WAN Port
If you want the router to respond to a 'ping' from the Internet, click the ‘Respond to Ping on
Internet WAN Port’ check box. This should only be used as a diagnostic tool, since it allows your
router to be discovered. Don't check this box unless you have a specific reason to do so.
Setting the MTU Size
The default MTU size is usually fine. The normal MTU (Maximum Transmit Unit) value for most
Ethernet networks is 1500 Bytes. For some ISPs, particularly some using PPPoE, you may need to
reduce the MTU. This should not be done unless you are sure it is necessary by your ISP.
Any packets sent through the router that are larger than the configured MTU size will be
repackaged into smaller packets to meet the MTU requirement. To change the MTU size:
1. Under MTU Size, enter a new size between 64 and 1500.
2. Click Apply to save the new configuration.

Using the LAN IP Setup Options
The second feature category under the Advanced heading is LAN IP Setup. This menu allows
configuration of LAN IP services such as DHCP and RIP. From the Main Menu of the browser
interface, under Advanced, click on LAN IP Setup to view the LAN IP Setup menu, shown below.
Figure 7-3: LAN IP Setup Menu
Configuring LAN TCP/IP Setup Parameters
The router is shipped preconfigured to use private IP addresses on the LAN side, and to act.as a
DHCP server. The router’s default LAN IP configuration is:
• LAN IP addresses—192.168.0.1
• Subnet mask—255.255.255.0
7-6 Advanced Configuration of the Router
202-10039-01
Reference Manual for the MR814 v3 Cable/DSL Wireless Router
These addresses are part of the IETF-designated private address range for use in private networks,
and should be suitable in most applications. If your network has a requirement to use a different IP
addressing scheme, you can make those changes in this menu.
The LAN IP parameters are:
• IP Address
This is the LAN IP address of the router.
• IP Subnet Mask
This is the LAN Subnet Mask of the router. Combined with the IP address, the IP Subnet Mask
allows a device to know which other addresses are local to it, and which must be reached
through a gateway or router.
• RIP Direction
RIP (Router Information Protocol) allows a router to exchange routing information with other
routers. The RIP Direction selection controls how the router sends and receives RIP packets.
Both is the default.
— When set to Both or Out Only, the router will broadcast its routing table periodically.
— When set to Both or In Only, it will incorporate the RIP information that it receives.
— When set to None, it will not send any RIP packets and will ignore any RIP packets
received.
• RIP Version
This controls the format and the broadcasting method of the RIP packets that the router sends.
(It recognizes both formats when receiving.) By default, this is set for RIP-1.
— RIP-1 is universally supported. RIP-1 is probably adequate for most networks, unless you
have an unusual network setup.
— RIP-2 carries more information. RIP-2B uses subnet broadcasting.
Note: If you change the LAN IP address of the router while connected through the
browser, you will be disconnected. You must then open a new connection to the new IP
address and log in again.
Advanced Configuration of the Router 7-7
202-10039-01
Reference Manual for the MR814 v3 Cable/D SL Wir ele ss Ro ute r
Using the Router as a DHCP server
By default, the router will function as a DHCP (Dynamic Host Configuration Protocol) server,
allowing it to assign IP, DNS server, and default gateway addresses to all computers connected to
the router's LAN. The assigned default gateway address is the LAN address of the router. IP
addresses will be assigned to the attached PCs from a pool of addresses specified in this menu.
Each pool address is tested before it is assigned to avoid duplicate addresses on the LAN.
For most applications, the default DHCP and TCP/IP settings of the router are satisfactory. See “IP
Configuration by DHCP” on page B-10 for an explanation of DHCP and information about how to
assign IP addresses for your network.
If another device on your network will be the DHCP server, or if you will manually configure the
network settings of all of your computers, clear the ‘Use router as DHCP server’ check box.
Otherwise, leave it checked.
Specify the pool of IP addresses to be assigned by setting the Starting IP Address and Ending IP
Address. These addresses should be part of the same IP address subnet as the router’s LAN IP
address. Using the default addressing scheme, you should define a range between 192.168.0.2 and
192.168.0.253, although you may wish to save part of the range for device s with fixed addresses.
The router will deliver the following parameters to any LAN device that requests DHCP:
• An IP Address from the range you have defined
• Subnet Mask
• Gateway IP Address (the router’s LAN IP address)
• Primary DNS Server (if you entered a Primary DNS address in the Basic Settings menu;
otherwise, the router’s LAN IP address)
• Secondary DNS Server (if you entered a Secondary DNS address in the Basic Settings menu
Using Address Reservation
When you specify a reserved IP address for a PC on the LAN, that PC will always receive the
same IP address each time it access the router’s DHCP server. Reserved IP addresses should be
assigned to servers that require permanent IP settings.
To reserve an IP address:
1. Click the Add button.
7-8 Advanced Configuration of the Router
202-10039-01
Reference Manual for the MR814 v3 Cable/DSL Wireless Router
In the IP Address box, type the IP address to assign to the PC or server.
2.
(choose an IP address from the router’s LAN subnet, such as 192.168.0.X)
3. Type the MAC Address of the PC or server.
(Tip: If the PC is already present on your network, you can copy its MAC address from the
Attached Devices menu and paste it here.)
4. Click Apply to enter the reserved address into the table.
Note: The reserved address will not be assigned until the next time the PC contacts the router's
DHCP server. Reboot the PC or access its IP configuration and force a DHCP release and renew.
To edit or delete a reserved address entry:
1. Click the button next to the reserved address you want to edit or delete.
2. Click Edit or Delete.
Using a Dynamic DNS Service
If your network has a permanently assigned IP address, you can register a domain name and have
that name linked with your IP address by public Domain Name Servers (DNS). However, if your
Internet account uses a dynamically assigned IP address, you will not know in advance what your
IP address will be, and the address can change frequently. In this case, you can use a commercial
dynamic DNS service, who will allow you to register your domain to their IP address, and will
forward traffic directed at your domain to your frequently-changing IP address.
Note: If your ISP assigns a private WAN IP address (such as 192.168.x.x or 10.x.x.x),
the dynamic DNS service will not work because private addresses will not be routed on
the Internet.
The router contains a client that can connect to many popular dynamic DNS services. You can
select one of these services and obtain an account with them. Then, whenever your ISP-assigned
IP address changes, your router will automatically contact your dynamic DNS service provider,
log in to your account, and register your new IP address.
From the Main Menu of the browser interface, under Advanced, click on Dynamic DNS. To
configure Dynamic DNS:
1. Register for an account with one of the dynamic DNS service providers whose names appear
in the ‘Select Service Provider’ box. For example, for dyndns.org, go to www.dyndns.org.
Advanced Configuration of the Router 7-9

3. Select the name of your dynamic DNS Service Provider.
4. Type the Host Name (or domain name) that your dynamic DNS service provider gave you.
5. Type the User Name for your dynamic DNS account.
6. Type the Password (or key) for your dynamic DNS account.
7. If your dynamic DNS provider allows the use of wildcards in resolving your URL, you may
select the Use wildcards check box to activate this feature.
For example, the wildcard feature will cause *.yourhost.dyndns.org to be aliased to the same
IP address as yourhost.dyndns.org
8. Click Apply to save your configuration.
Configuring Static Routes
Static Routes provide additional routing information to your router. Under normal circumstances,
the router has adequate routing information after it has been configured for Internet access, and
you do not need to configure additional static routes. You must configure static routes only for
unusual cases such as multiple routers or multiple IP subnets located on your network.
From the Main Menu of the browser interface, under Advanced, click on Static Routes to view the
Static Route menu, shown below.

2.
Type a route name for this static route in the Route Name box under the table.
(This is for identification purpose only.)
3. Select Private if you want to limit access to the LAN only. The static route will not be reported
in RIP.
4. Select Active to make this route effective.
5. Type the Destination IP Address of the final destination.
6. Type the IP Subnet Mask for this destination.
If the destination is a single host, type 255.255.255.255.
7. T ype the Gateway IP Address, which must be a router on the same LAN segment as the router.
8. Type a number between 1 and 15 as the Metric value.
This represents the number of routers between your network and the destination. Usually, a
setting of 2 or 3 works, but if this is a direct connection, set it to 1.
9. Click Apply to have the static route entered into the table.
As an example of when a static route is needed, consider the following case:
• Your primary Internet access is through a cable modem to an ISP.
• You have an ISDN router on your home network for connecting to the company wh ere
you are employed. This router’s address on your LAN is 192.168.0.100.
• Your company’s network is 134.177.0.0.
Advanced Configuration of the Router 7-11
202-10039-01
Reference Manual for the MR814 v3 Cable/D SL Wir ele ss Ro ute r
When you first configured your router, two implicit static routes were created. A default route was
created with your ISP as the gateway, and a second static route was created to your local network
for all 192.168.0.x addresses. With this configuration, if you attempt to access a device on the
134.177.0.0 network, your router will forward your request to the ISP. The ISP forwards your
request to the company where you are employed, and the request will likely be denied by the
company’s firewall.
In this case you must define a static route, telling your router that 134.177.0.0 should be accessed
through the ISDN router at 192.168.0.100. The static route would look like Figure 7-5.
In this example:
• The Destination IP Address and IP Subnet Mask fields specify that this static route applies to
all 134.177.x.x addresses.
• The Gateway IP Address fields specifies that all traffic for these addresses should be
forwarded to the ISDN router at 192.168.0.100.
• A Metric value of 1 will work since the ISDN router is on the LAN.
• Private is selected only as a precautionary security measure in case RIP is activated.
Enabling Remote Management Access
Using the Remote Management page, you can allow a user or users on the Internet to configure,
upgrade and check the status of your MR814 v3 router.
Note: Be sure to change the router's default configuration password to a very secure
password. The ideal password should contain no dictionary words from any language,
and should be a mixture of letters (both upper and lower case), numbers, and symbols.
Your password can be up to 30 characters.
To configure your router for Remote Management:
1. Select the Turn Remote Management On check box.
2. Specify what external addresses will be allowed to access the router’s remote management.
Note: For enhanced security, restrict access to as few external IP addresses as practical.
a. To allow access from any IP address on the Internet, select Everyone.
7-12 Advanced Configuration of the Router

b.
Enter a beginning and ending IP address to define the allowed range.
c. To allow access from a single IP address on the Internet, select Only this PC.
Enter the IP address that will be allowed access.
3. Specify the Port Number that will be used for accessing the management interface.
Web browser access normally uses the standard HTTP service port 80. For greater security,
change the remote management web interface to a custom port by entering that number in the
box provided. Choose a number between 1024 and 65535, but do not use the number of any
common service port. The default is 8080, which is a common alternate for HTTP.
4. Click Apply to have your changes take effect.
Note: When accessing your router from the Internet, you will type your router's WAN IP address
into your browser's Address (in IE) or Location (in Netscape) bo x, follo wed by a colo n (:) an d the
custom port number. For example, if your external address is 134.177.0.123 and you use port
number 8080, you must enter http://134.177.0.123:8080 in your browser.
Using Universal Plug and Play (UPnP)
Universal Plug and Play (UPnP) helps devices, such as Internet appliances and computers,
access the network and connect to other devices as needed. UPnP devices can
automatically discover the services from other registered UPnP devices on the network.
Figure 7-6. UPnP Menu
Advanced Configuration of the Router 7-13
202-10039-01
Reference Manual for the MR814 v3 Cable/D SL Wir ele ss Ro ute r
From the Main Menu of the browser interface, under Advanced, click on UPnP. Set up UPnP
according to the guidelines below.
Turn UPnP On: UPnP can be enabled or disabled for automatic device configuration. The default
setting for UPnP is disabled. If disabled, the router will not allow any device to automatically
control the resources, such as port forwarding (mapping), of the router.
Note: If you use applications such as multi-player gaming, peer-to-peer connections, real time
communications such as instant messaging, or remote assistance (a feature in Windows XP), you
should enable UPnP.
Advertisement Period: The Advertisement Period is how often the router will broadcast its UPnP
information. This value can range from 1 to 1440 minutes. The default period is 30 minutes.
Shorter durations will ensure that control points have current device status at the expense of
additional network traffic. Longer durations may compromise the freshness of the device status but
can significantly reduce network traffic.
Advertisement Time To Live: The time to live for the advertisement is measured in hops (steps)
for each UPnP packet sent. The time to live hop count is the number of steps a broadcast packet is
allowed to propagate for each UPnP advertisement before it disappears. The number of hops can
range from 1 to 255. The default value for the advertisement time to live is 4 hops, which should
be fine for most home networks. If you notice that some devices are not being updated or reached
correctly, then it may be necessary to increase this value a little.
UPnP Portmap T able: The UPnP Portmap Table displays the IP address of each UPnP device that
is currently accessing the router and which ports (Internal and External) that device has opened.
The UPnP Portmap T able also displays what type of port is opened and if that port is still active for
each IP address.

Troubleshooting
This chapter gives information about troubleshooting your MR814 v3 Cable/DSL Wireless
Router. After each problem description, instructions are provided to help you diagnose and solve
the problem.
Basic Functioning
After you turn on power to the router, the following sequence of events should occur:
1. When power is first applied, verify that the Power light is on.
2. After approximately 10 seconds, verify that:
a. The power light is solid green.
b. The LAN port lights are lit for any local ports that are connected.
c. The Internet port light is lit.
If a port’s light is lit, a link has been established to the connected device. If a LAN port is
connected to a 100 Mbps device, verify that the port’ s light is green. If the port is 10 Mbps, the
light will be amber.
If any of these conditions does not occur, refer to the appropriate following section.
Power Light Not On
If the Power and other lights are off when your router is turned on:
• Make sure that the power cord is properly connected to your router and that the power supply
adapter is properly connected to a functioning power outlet.
• Check that you are using the 12 V DC 1A power adapter supplied by NETGEAR for this
product.
If the error persists, you have a hardware problem and should contact technical support.

Lights Never Turn Off
When the router is turned on, the lights turns on for about 10 seconds and then turn off. If all the
lights stay on, there is a fault within the router.
If all lights are still on one minute after power up:
• Cycle the power to see if the router recovers.
• Clear the router’s configuration to factory defaults. This will set the router’s IP address to
192.168.0.1. This procedure is explained in “Restoring the Default Configuration and
Password” on page 8-7.
If the error persists, you might have a hardware problem and should contact technical support.
LAN or WAN Port Lights Not On
If either the LAN lights or Internet light do not light when the Ethernet connection is made, check
the following:
• Make sure that the Ethernet cable connections are secure at the router and at the hub or
workstation.
• Make sure that power is turned on to the connected hub or workstation.
• Be sure you are using the correct cable:
— When connecting the router’s Internet port to a cable or DSL modem, use the cable that
was supplied with the cable or DSL modem. This cable could be a standard
straight-through Ethernet cable or an Ethernet crossover cable.

Troubleshooting the Web Configuration Interface
If you are unable to access the router’s web Configuration interface from a computer on your local
network, check the following:
• Check the Ethernet connection between the computer and the router as described in the
previous section.
• Make sure your computer’s IP address is on the same subnet as the router. If you are using the
recommended addressing scheme, your computer’s address should be in the range of
192.168.0.2 to 192.168.0.254. Refer to “Verifying TCP/IP Properties” on page C-8 or
“Verifying TCP/IP Properties for Macintosh Computers” on page C-19 to find your
computer’s IP address. Follow the instructions in Appendix C to configure your computer.
Note: If your computer’s IP address is shown as 169.254.x.x: Recent versions of Windows
and MacOS will generate and assign an IP address if the computer cannot reach a DHCP
server. These auto-generated addresses are in the range of 169.254.x.x. If your IP address is in
this range, check the connection from the computer to the router and reboot your computer.
• If your router’s IP address has been changed and you don’t know the current IP address, clear
the router’s configuration to factory defaults. This will set the router’s IP address to
192.168.0.1. This procedure is explained in “Restoring the Default Configuration and
Password” on page 8-7.
• Make sure your browser has Java, JavaScript, or ActiveX enabled. If you are using Internet
Explorer, click Refresh to be sure the Java applet is loaded.
• Try quitting the browser and launching it again.
• Make sure you are using the correct login information. The factory default login name is
admin and the password is password. Make sure that CAPS LOCK is off when entering this
information.
If the router does not save changes you have made in the web Configuration Interface, check the
following:
• When entering configuration settings, be sure to click the APPLY button before moving to
another menu or tab, or your changes are lost.
• Click the Refresh or Reload button in the web browser. The changes may have occurred, but
the web browser may be caching the old configuration.

Troubleshooting the ISP Connection
If your router is unable to access the Internet, you should first determine whether the router is able
to obtain a WAN IP address from the ISP. Unless you have been assigned a static IP address, your
router must request an IP address from the ISP. You can determine whether the request was
successful using the web Configuration Manager.
To check the WAN IP address:
1. Launch your browser and select an external site such as www.netgear.com
2. Access the Main Menu of the router’s configuration at http://www.routerlogin.net.
3. Under the Maintenance heading, select Router Status
4. Check that an IP address is shown for the WAN Port
If 0.0.0.0 is shown, your router has not obtained an IP address from your ISP.
If your router is unable to obtain an IP address from the ISP, you may need to force your cable or
DSL modem to recognize your new router by performing the following procedure:
1. Turn off power to the cable or DSL modem.
2. Turn off power to your router.
3. Wait five minutes and reapply power to the cable or DSL modem.
4. When the modem’s lights indicate that it has reacquired sync with the ISP, reapply power to
your router.
5. Then restart your computer.
If your router is still unable to obtain an IP address from the ISP, the problem may be one of the
following:
• Your ISP may require a login program.
Ask your ISP whether they require PPP over Ethernet (PPPoE) or some other type of login.
• If your ISP requires a login, you may have incorrectly set the login name and password.
• Your ISP may check for your computer's host name.
Assign the computer Host Name of your ISP account as the Account Name in the Basic
Settings menu.
• Your ISP only allows one Ethernet MAC address to connect to Internet, and may check for
your computer’s MAC address. In this case:
8-4 Troubleshooting
202-10039-01
Reference Manual for the MR814 v3 Cable/DSL Wireless Router
Inform your ISP that you have bought a new network device, and ask them to use the router’s
MAC address.
OR
Configure your router to spoof your computer’s MAC address. This can be done in the Basic
Settings menu. Refer to “How to Bypass the Configuration Assistant” on page 3-12.
If your router can obtain an IP address, but your computer is unable to load any web pages from
the Internet:
• Your computer may not recognize any DNS server addresses.
A DNS server is a host on the Internet that translates Internet names (such as www addresses)
to numeric IP addresses. Typically your ISP will provide the addresses of one or two DNS
servers for your use. If you entered a DNS address during the router’s configuration, reboot
your computer and verify the DNS address as described in “Install or Verify Windows
Networking Components” on page C-9. Alternatively, you may configure your computer
manually with DNS addresses, as explained in your operating system documentation.
• Your computer may not have the router configured as its TCP/IP gateway.
If your computer obtains its information from the router by DHCP, reboot the comput er and
verify the gateway address as described in “Install or Verify Windows Networking
Components” on page C-9.
Troubleshooting a TCP/IP Network Using a Ping Utility
Most TCP/IP terminal devices and routers contain a ping utility that sends an echo request packet
to the designated device. The device then responds with an echo reply. Troubleshooting a TCP/IP
network is made very easy by using the ping utility in your computer or workstation.
Testing the LAN Path to Your Router
You can ping the router from your computer to verify that the LAN path to your router is set up
correctly.
To ping the router from a PC running Windows 95 or later:
1. From the Windows toolbar, click on the Start button and select Run.
2. In the field provided, type Ping followed by the IP address of the router, as in this example:
ping 192.168.0.1

Click on OK.
3.
You should see a message like this one:
Pinging <IP address> with 32 bytes of data
If the path is working, you see this message:
Reply from < IP address >: bytes=32 time=NN ms TTL=xxx
If the path is not working, you see this message:
Request timed out
If the path is not functioning correctly, you could have one of the following problems:
• Wrong physical connections
— Make sure the LAN port LED is on. If the LED is off, follow the instructions in “LAN
or WAN Port Lights Not On” on page 8-2.
— Check that the corresponding Link LEDs are on for your network interface card and
for the hub ports (if any) that are connected to your workstation and router.
• Wrong network configuration
— Verify that the Ethernet card driver software and TCP/IP software are both installed
and configured on your computer or workstation.
— Verify that the IP address for your router and your workstation are correct and that the
addresses are on the same subnet.
Testing the Path from Your Computer to a Remote Device
After verifying that the LAN path works correctly, test the path from your computer to a remote
device. From the Windows run menu, type:
PING -n 10 <IP address>
where <IP address> is the IP address of a remote device such as your ISP’s DNS server.
If the path is functioning correctly, replies as in the previous section are displayed. If you do not
receive replies:
— Check that your computer has the IP address of your router listed as the default gateway. If
the IP configuration of your computer is assigned by DHCP, this information will not be
visible in your computer’s Network Control Panel. Verify that the IP address of the router
is listed as the default gateway as described in “Install or Verify Windows Networking
Components” on page C-9.
8-6 Troubleshooting
202-10039-01
Reference Manual for the MR814 v3 Cable/DSL Wireless Router
— Check to see that the network address of your computer (the portion of the IP address
specified by the netmask) is different from the network address of the remote device.
— Check that your cable or DSL modem is connected and functioning.
— If your ISP assigned a host name to your computer, enter that host name as the Account
Name in the Basic Settings menu.
— Your ISP could be rejecting the Ethernet MAC addresses of all but one of your computers.
Many broadband ISPs restrict access by only allowing traffic from the MAC address of
your broadband modem, but some ISPs additionally restrict access to the MAC address of
a single computer connected to that modem. If this is the case, you must configure your
router to “clone” or “spoof” the MAC address from the authorized computer. Refer to
“How to Bypass the Configuration Assistant” on page 3-12.
Restoring the Default Configuration and Password
This section explains how to restore the factory default configuration settings, changing the
router’s administration password to password and the IP address to 192.168.0.1. You can erase the
current configuration and restore factory defaults in two ways:
• Use the Erase function of the router (see “Erasing the Configuration” on page 6-7).
• Use the Default Reset button on the rear panel of the router. Use this method for cases when
the administration password or IP address is not known.
To restore the factory default configuration settings without knowing the administration password
or IP address, you must use the Default Reset button on the rear panel of the router.
1. Press and hold the Default Reset button until the power light blinks on (about 10 seconds).
2. Release the Default Reset button and wait for the router to reboot.
If the router fails to restart or the power light continues to blink or turns solid amber, the unit
may be defective. If the error persists, you might have a hardware problem and should contact
technical support.

Problems with Date and Time
The E-Mail menu in the Content Filtering section displays the current date and time of day. The
MR814 v3 router uses the Network Time Protocol (NTP) to obtain the current time from one of
several Network Time Servers on the Internet. Each entry in the log is stamped with the date and
time of day. Problems with the date and time function can include:
• Date shown is January 1, 2000. Cause: The router has not yet successfully reached a Network
Time Server. Check that your Internet access settings are configured correctly . If you have just
completed configuring the router , wait at least five minutes and check the date and time again.
• Time is off by one hour. Cause: The router does not automatically sense Daylight Savings
Time. In the E-Mail menu, check or uncheck the box marked “Adjust for Daylight Savings
Time”.
