I have been doing the service checks too and I got nothing. However, I wanted to see if I hard wired it would make a difference. I used a Powerline Ethernet adapter and usually when I turn the TV off one of the lights goes out (the active link light). My last time running it, al three lights stayed on for ~5 minutes. When I came back in the room the light was off. I turned the TV back on and it said that I got the update so in this case I was able to see something different on the networking side. I did try to reconnect to my 5GHz network and it wouldn't connect so I don't know if they fixed the problems I was having with 5GHz.I'm beginning to wonder if my repeated emails, phone calls, and online chat sessions with Vizio support somehow placed me on a FW update ignore list. Haha. I was fairly abrasive with my requests as of late because I could never seem to get a straight answer. I plan to 'service check' all week and we shall see what that brings. If no dice, I will call them on Thursday.
