Wifi Connect/Disconnect

Firmware Issue?  I have the same wifi disconnect/reconnect issue others have talked about, several times a day.

Got new card for 4g, one day later started again. Reset everything, lasted almost one day.  

Thinking back, I did not install the system firmware update until late June. Coincidentally, that's when the problem started. Related?

Just a thought, no one else has brought it up.
