Troubleshooting 

The ZyAIR computer cannot 
communicate with the other 
computer.  

 

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

working properly.  
Make sure the ZyAIR 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 Security screen. 

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

Make sure the ZyAIR 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. 

The Link Quality is poor all 
the time. 

Move your computer closer to the AP or the peer computer(s) within the 
transmission range. 
There is too much radio interference (for example microwave or another 
AP using the same channel) around your wireless network.  Relocate or 
reduce the radio interference. 

The Link Strength is poor 
all the time.  

Move your computer closer to the AP or peer computer(s) within the 
transmission range. 
There is too much radio interference (for example microwave or another 
AP using the same channel) around your wireless network.  Relocate or 
reduce the radio interference.
