There are no silver bullet solutions...you will have to do some troubleshooting to get some better leads. Start by checking that the upper antennas are all properly connected and not damaged. If that looks good, check the WLAN IC and the associated power rails to see if those are okay. Get back to us with this info and perhaps give us more background on the history of the device as that may provide more clues.
