Hi everyone, I have some strange problems on my alu iMac. When I first got my iMac I used airport a lot. And it worked very well. Then I switched over to cable, because it was possible. But now I am back at some wireless place and I have strange troubles with the Airport. When I connect to a network everything works fine. But out of a sudden the connection stops. The triangle still indicates a good reception, but I can't even ping the default gateway. This happens even in Bootcamp. The connection is alive for at most 30 seconds to 1 minute or so. Does anyone have the same problems? I think the hardware is fine as it works before, but it is the same problem in bootcamp, so I guess it is firmware related. Here is some stuff that I have in my System log: Jun 8 00:20:48 localhost kernel: AirPort: Roam (Beacons Lost) Jun 8 00:20:52 localhost kernel: AppleYukon2 - en0 link active, 100-Mbit, full duplex, symmetric flow control enabled port 0 Jun 8 00:21:10 localhost kernel: WLC_E_COUNTRY_CODE_CHANGED Jun 8 00:21:10 localhost SystemUIServer: Error: airportd MIG failed = 1 ((os/kern) invalid address) (port = 60263) Jun 8 00:21:10 localhost kernel: en1: 802.11d country code set to 'X3'.
