Hi,

I just bought a new white Macbook last week (updated to Mac OS X 10.6.6), and have been getting repeated issues with the Airport connection.

Symptoms:

* Mac joining the wireless network fine, getting IP address etc
* Connectivity works fine for 10 - 20 minutes, then stops
* Still wireless signal, but no connectivity. Can't even access the router admin pages
* Only fix is to stop Airport and start again (click on menu). Connectivity comes back instantly


Steps taken to try to correct wireless connection dropping off:

* Changed channel on router (2, 10, 11 etc)
* Changed encryption from WPA to Wep
* Set network location on Mac
* Set fixed IP address on Mac
* Deleted some network config files and rebooted
* Erased hard drive and reinstalled 10.6.4 (same issue)
* Reset PRAM and NVRAM

Other computers on the same network don't have any issues with the same Wifi network:

* Lenovo Thinkpad
* Dell Latitude
* Acer Revo desktop
* Amazon Kindle
* Internet Radio

Could someone suggest how to fix this? It looks to me that it is a hardware fault. I have an appointment at a Genius bar on Saturday, but not sure they will be able to replace the wifi card quickly.

Thanks,
Tom
