Appendix A - Troubleshooting
Rules to specify the PC which will receive the incoming traffic.
You can also 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 Wireless 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 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 ADSL Router must have the same
setting for WEP. The default setting for the Wireless ADSL Router is
disabled, so your wireless station should also have WEP disabled.
•
If WEP is enabled on the Wireless ADSL Router, your PC must have
WEP enabled, and the key must match.
•
If the Wireless ADSL Router's Wireless screen is set to Allow Trusted
PCs only , then each of your Wireless stations must have been designat-
ed as "Trusted", or the Wireless station will be blocked.
•
To see if radio interference is causing a problem, see if connection is
possible when close to the Wireless ADSL Router.
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:
•
Wireless ADSL Router location.
Try adjusting the location and orientation of the Wireless ADSL Rou-
ter.
•
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 Wireless ADSL Router.
