Same thing here. Perfect on 2.1, but was the same as above when I tried v0.1 BB, and is still the same on v0.3. Wifi works (WPA, no MAC filtering), but indicator in notification bar shows zero activity, and wifi in settings and with Wifi Analyzer shows signal spiking up and down constantly. Doesn't seem like it would be good for battery life. Just installed v0.3, wiped data and cache few times first, stock kernel, pretty much stock everything as of yet.
