Wireless Access - Advantech UniGateway EH-2101W User Manual

Problem 2: Some applications do not run properly when using the UniGateway.
Solution 2: The UniGateway EH-2101W 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:

Problem 1:
My PC can't locate the Wireless Access Point.
Check the following.

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:
•

It is a security risk, since the firewall is disabled.
Only one (1) PC can use this feature.
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 "Work-
group" does NOT match "workgroup".
Both your PC and the Wireless Access Point must have the same setting
for WEP. The default setting for the UniGateway EH-2101W is dis-
abled, so your wireless station should also have WEP disabled.
If WEP is enabled on the UniGateway EH-2101W, your PC must have
WEP enabled, and the key tables (for 64 Bit encryption) or key (for 128
Bit encryption) must match.
If the UniGateway EH-2101W'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 Wireless Access Point.
Remember that the connection range can be as little as 100 feet in poor
environments.
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.
