The Air3G features emergency firmware upgrade function that can restore your AP from a 
firmware crashed.    If you can’t access your AP anymore, please first try to restore the 
setting to default by holding the RESET button (in the back) for more than 10 seconds. You 
should be able to find the AP at 192.168.1.254.    If you can’t find it, then please perform the 
emergency upgrade. Please visit 

->support->download and type “Air3G” to 

the download page. 
 
 
 

 
Air3G’s flash memory is divided into “firmware” and “bootloader” area.    The bootloader 
area is protected from writing and has a built-in emergency web server.   Therefore, the AP 
can be recovered from emergency web server after a firmware crash.    The emergency 
web server is enabled when AP is forced into emergency upgrade mode, it’s IP will be 
changed to

 192.168.1.254.
