Hardware Error after resume from standby

Dear Forum users, I have a fresh installation of Windows XP via BootCamp on my MacBook C2D (late 2006). I have Leopard installed. I've installed the Windows drivers that ship with Leopard dvd.

Everytime that I resume from standby in Windows the wireless network does not work. I get an "Hardware Error" if I try to ping any ip address with my wireless network card (the wired network card works fine).

Then I reboot my Mac and everything works fine until next standby.

Please note that with BootCamp Beta 1.4 everything worked fine.

I've had the same problem with BootCamp 1.3 but the upgrade to 1.4 solved the problem.

Any help?

Is there a place where to download updated bootcamp windows drivers?

Best regards
