Finally! someone has my same problem! I found out, too, by exploration, that it is related to the bridge. Problem is, i have an ALi chipset and there are no drivers for it that work correctly on vista.(this is my notebook, by the way). I have gotten my wlan card to work, but the sound will crash/halt the system completely. and every once in a while if i insert the card the system will halt. So in pre-beta1 builds, i would have to choose between one or the other, therefore i couldnt do streaming video or anything like that. What kind of chipset do you have, Lotacus? Your wireless card uses the same broadcom 4306 chipset as my Motorola WN825G, 'cept mine aint got speed-booster...
