Hi, I am at the end of my rope with our Sony Bravia KDL55NX720 and looking for some help. We bought this set in April 2012 and up until a week or so ago the built-in wifi worked perfectly and we could stream internet content without any problems. We stream Netflix and Pandora via the built-in wifi and for the last week or so I have to reset our Uverse gateway (router) every day for the connection to get re-established with the Sony. Everything works until the next day at which point I have to reset Uverse router again. So we get about 24 hours out of one router reboot.
I have tried everything I can think to do. For instance, I have...
done a factory reset on the Sony set
unplugged the Sony and then reset the wireless router before plugging the Sony back in
logged out of Netflix and re-activated via the Sony set (although I get the same error when trying to launch the built-in Pandora app)
Manually downloaded software update (got the message that the software is up to date)
What's bizarre is we've had NO issues using the internet content via the Sony until about a week ago. Anytime I get the "a network error has occurred" message, our other wireless devices all work fine and the speed is excellent. So this issue is limited to just the Sony. When I try to reestablish connection through the Sony GUI, it detects our wireless network but fails to connect until I reboot the wireless router. The location of the Uverse router has not posed a problem for over a year, although I doubt that is the issue since the connection is fine once I reset the router.
Maybe there is some specific order in which I should be doing things?? It seems like this is a Sony software related issue since we can stream content fine (for a day anyway) once i reboot the router. Thanks in advance for any help you can provide!
