How to change the Country Code of en1 AirPort Extreme?
iMac, OS X Mountain Lion (10.8.4)
I have the same problem. I've never seen a fix despite tons of googling. The MacBook Pro I use patently does not change its country and channels according to the router. I'm thinking the simple answer in all this is don't expect a Mac to work on WiFi especially if you move around the world a bit.
It is controlled by your router. Also you change channels on your router not on the computer. The computer will connect to any channel the router is set to. If you can change the channel on the computer and you change it to something other than what the router is set to you'll never get a connection.
Thanks for reply.
But the CC(Country Code) of my router is TW, so I really don't understand how router control the CC of my AirPort Extreme Card in board.
BTW I can use the following channel when CC is JP:
1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 36, 40, 44, 48, 52, 56, 60, 64, 100, 104, 108, 112, 116, 120, 124, 128, 132, 136, 140
and here is the available channel when CC is TW :
1 2 3 4 5 6 7 8 9 10 11 56 60 64 100 104 108 112 116 120 124 128 132 136 140 149 153 157 161 165

for example, when my router (buy in TW) set the channel to 157 automaticly (in 5Ghz), my iMac can't find the signal.

I Have the same problem. My MacBook Pro has up to channel 140. I can not connect to the network 5g. my router can only connect to the channels 161, 156 and my computer does not support them.
Hello,
I also have the same problem: Mac mini's wifi country code-- JP, but Airport Extreme's country code-- TW.
They don't have any cover channel on 5GHz.
Is there any solution to change Mac mini's country code ? Please~~~
I believe many people have the same problem
