I have the 46es7000 bought around 2012. Still love this tv and is my bedroom tv now, as have 3 other newer Samsungs in other rooms. It was one of the first Samsung smart TVs and had all the options at the time 3D and gesture control (never use them now though). i had an Amazon firestick, and chrome cast in it, so hadn't had to use the smart hub for probably a couple of years actuall for any apps or streaming services, as can all be got on the firestick but recently had moved the firestick to one of the other TVs and went back to use the smart hub on this tv and found the wifi wouldn't pick up. Tried all the usual resets and ip settings and combos suggested and being an IT veteran I doubted a wifi card fault, as it would unusual for it to go and the telly not complain about it when everything else is fine and no clear known fault for it on forums etc. I also wanted to ensure it tried all firmware and config options before going to the wifi card as I would do with any computer or device fault and if device manager can see and check the device. Saw your post and used your suggestion and just to reiterate what I did: -
With telly off, on remote press "info" then "menu" then "mute" then "power on" to take it into diags. Then select "control" then "sub option" and low and behold "wifi region" option was set at E!
Select and changed to "A" and saved that.
TV off and on, then into menu, network settings and start to look for wifi networks and voila, they all came up. Well the 2G versions as it is an older wifi adapter after all before 5G was the offered!
cost £zero, time 20 mins roughly, all good :-).
Thanks so much we've also had the exact same issues. I'm in Australia where do I find the correct wifi region to use ?
If you read my reply a few posts up (I am in Australia) I used Region A and it solved the issue.

After hours of frustration and updating firmware, checking/rechecking the modem, etc. and looking up the internet for solutions - I finally found this thread. (Am in Australia)
Thanks to this discussion I have got my UA55ES7500M smart tv to see the Wifi that it wouldn't previously.
My Wifi Area was set to O which I changed to Area A and bingo it fixed the issue and could see it immediately.
Not sure if the Firmware update resets the Area - but I recommend the method!
So thanks again!!!
