WRT-2110


App A. Troubleshooting

This chapter covers some common problems that may be encountered while using the WRT-2110 and some possible solutions to them. If you follow the suggested steps and the WRT-2110 still does not function properly, contact your dealer for further advice.

A.1 General Problems

Problem 1:
Can't connect to the WRT-2110 to configure it.
Solution 1:
Check the following:
  • The WRT-2110 is properly installed, LAN connections are OK, and it is powered ON.
  • Ensure that your PC and the WRT-2110 are on the same network segment. (If you don't have a router, this must be the case.)
  • Ensure that your PC is using an IP Address within the range 192.168.0.2 to 192.168.0.254 and thus compatible with the WRT-2110's default IP Address of 192.168.0.1.
    Also, the Network Mask should be set to 255.255.255.0 to match the WRT-2110.
    In Windows, you can check these settings by using Control Panel-Network to check the Properties for the TCP/IP protocol.



A.2 Internet Access

Problem 1:
When I enter a URL or IP address I get a time out error.
Solution 1:
A number of things could be causing this. Try the following troubleshooting steps.
  • Check if other PCs work. If they do, ensure that your PCs IP settings are correct (IP address, Network Mask, Default gateway and DNS).
  • If the PCs are configured correctly, but still not working, check the WRT-2110. Ensure that it is connected and ON. Connect to it and check its settings. (If you can't connect to it, check the LAN and power connections.)
  • If the WRT-2110 is configured correctly, check your Internet connection (DSL/Cable modem etc) to see that it is working correctly.
Problem 2:
Some applications do not run properly when using the WRT-2110.
Solution 2:
The WRT-2110 processes the data passing through it, so it is not transparent.
Use the Special Applications feature to allow the use of Internet applications which do not function correctly.
If this does solve the problem you can use the DMZ function. This should work with almost every application, but:
  • It is a security risk, since the firewall is disabled.
  • Only one (1) PC can use this feature.
  • When the DMZ feature is being used, the Special Applications and Virtual Server features should be disabled.


A.3 Wireless Access

Problem 1:
My PC can't locate the Wireless Access Point
Solution 1:
Check the following.
  • Your PC is set to Infrastructure Mode.
  • The wireless channel used matches the wireless channel on the Access Point.
  • The SSID on your PC and the Wireless Access Point are the same.
    Remember that the SSID is case-sensitive. So, for example "Workgroup" does NOT match "workgroup".
  • Both your PC and the Wireless Access Point must have the same setting for WEP. The default setting for the WRT-2110 is disabled, so your wireless station should also have WEP disabled.
  • If WEP is enabled, the key tables must match.
  • If the Wireless Station access permission on the WRT-2110's Wireless screen is set to Only allow access if on this list, then each Wireless station must have its address correctly entered.
  • To see if radio interference is causing a problem, see if connection is possible when close to the Wireless Access Point.
    Remember that the connection range can be as little as 100 feet in poor environments.
Problem 2:
Wireless connection speed is very slow.
Solution 2:
The wireless system will connect at the highest possible speed, depending on the distance and the environment. To obtain the highest possible connection speed, you can experiment with the following:
  • Access Point location.
    Try adjusting the location and orientation of the Access Point.
  • Wireless Channel
    If interference is the problem, changing to another channel may show a marked improvement.
  • Radio Interference
    Other devices may be causing interference. You can experiment by switching other devices Off, and see if this helps. Any "noisy" devices should be shielded or relocated.
  • RF Shielding
    Your environment may tend to block transmission between the wireless stations. This will mean high access speed is only possible when close to the Access Point.
