Question
:
When I connect my PoE switch with Air3G, why doesn’t it work?
Answer: The Air3G use a 12V Passive PoE system, it is not the same as the 48V
system used by PoE switch. As matter of fact, connect the 48V system to
the Air3G might damage the device!

Question
:
I thought the Air3G has 30dBm output power, why do I only see 20dBm on the
Tx Output Power option?
Answer: The maximum output power for Air3G is about 1watt(30dBm). However, it is
limited to 20dBm in EU and 23dBm in the U.S. for compliance with regulations.
Nevertheless, unlike normal 11n routers that typically provide less than
15dBm output power in 11n mode, the Air3G can provides up to 19dBm(EU)
and 22dBm(FCC) in 11n mode. It means greater coverage in 11n mode.
If you are living in countries that allow use of 30dBm output power, you can
change the Regulatory Domain to South America. Please be sure it is legal
in your country, do not use the wrong regulatory domain.
