The wireless detection on my SL500 periodically (about every ~5 min.) stops working (LED off, does not detect networks) and has to undergo "Diagnosis and Repair" and "Turn on wireless capability." It was fine for a couple of months before.

no idea what your problem is...but you might want to see what version of the wireless driver you have installed. check the comment listed under "summary of changes" for the latest version here:
