I'm running CM7 7.0.3, nightly build 94 (just installed to attempt to fix this problem, was running 84) off an SD card. My NC is stuck in the "Obtaining IP Address... Scanning..." loop. So far none (and I mean none) of the suggested fixes online that I've found have fixed my problem. WiFi on the NC with CM7 has always been a bit finicky, but I've always been able to make it work after a little futzing. Here's why I'm thinking it has to be a driver issue. When I take the uSD card out and boot into the B&N UI, WiFi works fine and I can browse the web. Because of that, I know the problem isn't hardware related. The last thing I installed today before it stopped working was a bluetooth mouse and keyboard app. It was able to see the mouse, but I couldn't figure out how to use it, plus it was only a demo of the app, so I uninstalled it. That's the last known time the WiFi worked. I've been trying for a couple hours tonight to get it working, to no avail. I was running nightly build 87 and I figured I'd check to see if there's a newer one, and there was, 97, so I installed it. But that hasn't fixed the problem.
