I don't think that the issue is the router since my wife's G2 and other devices we have in the house still work fine on wi-fi.
Also it's not the rom because I have superwiped and reinstalled, then tried installing cm7, and ilwt. The issue persists on each rom. I have superwiped each time before installing.
I am really at a loss for what to do, I didn't change any settings on the phone and regardless, I don't know what I could have changed that would have carried over through flashing a new rom. I would appreciate any ideas on what to do.
ETA - I have changed the radio and the kernel and still no luck.
