Boot Camp Woes

For some time now I haven’t been able to detect wireless networks on my MBP under WinXP SP3. Unfortunately, I don’t remember precisely when this started happening since I hardly ever boot into Win, and when I do so I don’t usually use the internet.

I have no idea what the cause might be. All the other hardware works fine under WinXP. I have no issues with wireless connectivity under Mac OS.

I have tried reinstalling and also repairing the Boot Camp drivers from the Mac OS X 10.6 Install disc. IIRC the installation was done with Boot Camp 2.2, but the drivers should now be those that come with 3.0. Here is my configuration and some other stuff I have tried/checked:

MacBook Pro “Core Duo” 1.83 (MA463LL/A*)
Windows XP Professional - SP3 (Version 2002)
All updates currently available from Windows Update and Apple Software Update are installed.

Stuff I have tried/checked after some web surfing:
-Hardware manager reports the “Atheros AR5006X Wireless Network Adapter” is enabled and working properly.
-Wireless Zero Configuration service is running.

Router and settings I have tried:
Combo modem/router: Qwest ZyXEL PK5000Z
(All configurations tested with SSID broadcast)
-WPA-Personal, AES and TKIP
-WPA2-Personal, AES and TKIP
-WEP
-Unsecured 802.11b
-Unsecured 802.11g

I can’t see any of my neighbors’ networks, either, and I assume they use a variety of brands and security settings. At least one of their networks is unsecured. So, I am inclined to believe the problem is not with the wireless settings of my router or the router itself.
