Maybe this is old news, or maybe I'm the first one to get it to work, but I am currently running the GB version of CM7, and my Wifi is working. I know its working because the icon is show in the status bar, and in settings it gives me the correct router name, and says connected. I know that was a big bug for other people, and I think I may have fixed it. I'm not 100% sure, but I think what I did that fixed it was try to access one wifi point, and it didn't work. Because of another reason, I rebooted my phone, and then tried it again out of curiousty. No luck. But then when I went to another house, one with a saved wifi hot spot, my wifi automatically came on, and is working great. So maybe the key is to try to access one point, and then reboot, and then all other access points will work, I'm not sure.
