Wi-Fi network problems after screen replacement

I recently replaced my broken screen, and subsequently the power and sound button ribbon cable after breaking it. After piecing everything back together I am seeing some very strange responsiveness from my iPod. At first i thought i had broken or disconnected the wi-fi antenna but then i noticed for some reason that it still shows my ad-hoc network i created at my house, however it does not show my normal wi-fi netowrk. No other networks are shown anywhere, except for a weak signal in some areas at my school, and I've tried the "other..." option to no avail. I've also reset my network settings. Wi-fi works fine connected to the ad-hoc but i'm not sure what to do from this point, any help?

on a side note, i accidentally ripped the copper grounding on top of the rear facing camera and disconnected it from the body, will it be a big issue as long as the piece is still there or should i do something about it?
