Troubleshooting 

The ZyXEL AG-225H 
computer cannot 
communicate with the other 
computer. 

Make sure you are connected to the network. 

A.  Infrastructure   Make sure that the AP and the associated computers are turned on and 

working properly.  

Make sure the ZyXEL AG-225H computer and the associated AP use the 
same SSID. 

Change the AP and the associated wireless clients to use another radio 
channel if interference is high. 

Make sure that the computer and the AP share the same security option 
and key. Verify the settings in the Profile Security Settings screen. 

B.  Ad-Hoc (IBSS)   Verify that the peer computer(s) is turned on. 

Make sure the ZyXEL AG-225H computer and the peer computer(s) are 
using the same SS ID and channel.  

Make sure that the computer and the peer computer(s) share the same 
security option and key. 

Change the wireless clients to use another radio channel if interference is 
high. 

 

When using the Windows 
XP configuration tool, cannot 
scan for or connect to any 
access points.  

The ZyAIR might still be operating in access point mode. This results 
when you set the ZyAIR to operate in access point mode using the ZyXEL 
Utility, close the ZyXEL Utility and then use the Windows XP configuration 
tool.  

Before you use the Windows XP configuration tool, make sure you set the 
ZyAIR to operate in station mode before you close and exit the ZyXEL 
Utility.
