Appendix A Troubleshooting A This Appendix covers the most likely problems and their solutions. Overview This chapter covers some common problems that may be encountered while using the TEW431BRP and some possible solutions to them. If you follow the suggested steps and the TEW431BRP still does not function properly, contact your dealer for further advice. General Problems Problem 1: Solution 1: Can't connect to the TEW-431BRP to configure it. Check the following: • The TEW-431BRP is properly installed, LAN connections are OK, and it is powered ON. • Ensure that your PC and the TEW-431BRP are on the same network segment. (If you don't have a router, this must be the case.) • If your PC is set to "Obtain an IP Address automatically" (DHCP client), restart it. • If your PC uses a Fixed (Static) IP address, ensure that it is using an IP Address within the range 192.168.0.2 to 192.168.0.254 and thus compatible with the TEW-431BRP 's default IP Address of 192.168.0.1. Also, the Network Mask should be set to 255.255.255.0 to match the TEW-431BRP. In Windows, you can check these settings by using Control PanelNetwork to check the Properties for the TCP/IP protocol. Internet Access Problem 1: Solution 1: When I enter a URL or IP address I get a time out error. 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. If using a Fixed (Static) IP Address, check the Network Mask, Default gateway and DNS as well as the IP Address. • If the PCs are configured correctly, but still not working, check the TEW-431BRP. 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 TEW-431BRP is configured correctly, check your Internet connection (DSL/Cable modem etc) to see that it is working correctly. 79 TEW-431BRP User Guide Problem 2: Solution 2: Some applications do not run properly when using the TEW-431BRP. The TEW-431BRP 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. Wireless Access Problem 1: Solution 1: Problem 2: Solution 2: My PC can't locate the TEW-431BRP Access Point. Check the following. • Your PC is set to Infrastructure Mode. (Access Points are always in Infrastructure Mode) • The SSID on your PC and the TEW-431BRP are the same. Remember that the SSID is case-sensitive. So, for example "Workgroup" does NOT match "workgroup". • Both your PC and the TEW-431BRP must have the same setting for WEP. The default setting for the TEW-431BRP is disabled. If WEP is enabled on the TEW-431BRP, your PC must have WEP enabled, and the key must match. • If the TEW-431BRP's Wireless screen is set to Allow LAN access to selected Wireless Stations only, then each of your Wireless stations must have been selected, or access will be blocked. • To see if radio interference is causing a problem, see if connection is possible when close to the TEW-431BRP. Remember that the connection range can be as little as 100 feet in poor environments. Wireless connection speed is very slow. 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: • TEW-431BRP location. Try adjusting the location and orientation of the TEW-431BRP. • 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 TEW-431BRP. 80

Appendix A
Troubleshooting
This Appendix covers the most likely problems and their solutions.
Overview
This chapter covers some common problems that may be encountered while using the TEW-
431BRP and some possible solutions to them. If you follow the suggested steps and the TEW-
431BRP still does not function properly, contact your dealer for further advice.
General Problems
Problem 1:
Can't connect to the TEW-431BRP to configure it.
Solution 1:
Check the following:
•
The TEW-431BRP is properly installed, LAN connections are OK, and
it is powered ON.
•
Ensure that your PC and the TEW-431BRP are on the same network
segment. (If you don't have a router, this must be the case.)
•
If your PC is set to "Obtain an IP Address automatically" (DHCP
client), restart it.
•
If your PC uses a Fixed (Static) IP address, ensure that it is using an IP
Address within the range 192.168.0.2 to 192.168.0.254 and thus com-
patible with the TEW-431BRP 's default IP Address of 192.168.0.1.
Also, the Network Mask should be set to 255.255.255.0 to match the
TEW-431BRP.
In Windows, you can check these settings by using
Control Panel-
Network
to check the
Properties
for the TCP/IP protocol.
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. If using a Fixed (Static) IP Address, check the Network
Mask, Default gateway and DNS as well as the IP Address.
•
If the PCs are configured correctly, but still not working, check the
TEW-431BRP. 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 TEW-431BRP 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 TEW-431BRP.
Solution 2:
The TEW-431BRP processes the data passing through it, so it is not trans-
parent.
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.
Wireless Access
Problem 1:
My PC can't locate the TEW-431BRP Access Point.
Solution 1:
Check the following.
•
Your PC is set to
Infrastructure Mode
. (Access Points are always in
Infrastructure Mode
)
•
The SSID on your PC and the TEW-431BRP are the same.
Remember that the SSID is case-sensitive. So, for example "Work-
group" does NOT match "workgroup".
•
Both your PC and the TEW-431BRP must have the same setting for
WEP. The default setting for the TEW-431BRP is disabled.
If WEP is enabled on the TEW-431BRP, your PC must have WEP en-
abled, and the key must match.
•
If the TEW-431BRP's
Wireless
screen is set to
Allow LAN access to
selected Wireless Stations only
, then each of your Wireless stations
must have been selected, or access will be blocked.
•
To see if radio interference is causing a problem, see if connection is
possible when close to the TEW-431BRP.
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 connec-
tion speed, you can experiment with the following:
•
TEW-431BRP location.
Try adjusting the location and orientation of the TEW-431BRP.
•
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 TEW-431BRP.
