PS3 Update v.1.92 issues
According to some PS3 users (and my brother in law) the update has caused a few PS3’s to have network errors. One fix that was mentioned was to back up your ps3 info, format your drive, and reinstall the original stuff. Another way to do it is to restore factory defaults on the system. This has lead to a short term fix and not necessarily something that is long term but I think for now that might be a work around. I have also heard to fix your browser is to clear your cookies and cache (I just got off the phone with him and it looks like that has fixed his PSN and browser). I realize its tough but fight it out!
