I recently purchased a MBP 15" from tosh computers - imported from the US.

Everything was dandy till I tried to connect it to Wifi running on Channel 13

the MBP wasn't able to get a 802.11d packet from my router, and if I am following the situation correctly (since the 802.11d beacon sets the country code for the wifi adapter in Mac OS)

So, clearly my router isn't sending the correct packet out. is there any way to get it to send the right one? Because it sets my Wifi adapter to country code X0, so if you have say an imported MBP, it wont allow you to use channels 12 and 13.

These routers are pretty old, so my guess is that the type of response im going to get is to get a new router. But if there is a fix for it, I would greatly appreciate it.

PS: Please don't mention changing wifi channels. Long story short, the others are too congested.

Seems a mac issue, not a router issue since I have used imported phones on ch13 fine on all my routers. CH14 less sucess however.

On all my windows PCs there has been a dropdown list somewhere in theproperties of the wlan adapter to choose the country, and setting that to japan has opened up all 14 channels for me.

802.11d is optional, not a requirement. Its more used on corporate networks to limit the devices transmit power so they can have more channel reuse, but again, devices are free to ignore it and crank up 100mW if they choose to.
