Solution 2: 

The Wireless Router 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:

 

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 Router must have the same setting for 

WEP. The default setting for the Wireless Router is  disabled,  so  your 

wireless station should also have WEP disabled. 

 

If  WEP  is  enabled  on  the  Wireless  Router,  your  PC  must  have  WEP 

enabled, and the key must match. 

 

If the Wireless Router'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 

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 

connection speed, you can experiment with the following: 

 

Wireless Router location. 

Try adjusting the location and orientation of the Wireless Router. 

 

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 Router.
