I also have a Samsung UE40ES6300 TV and yesterday it suddenly stopped finding my or any other wireless nestworks.
I have reset the router, factory reset the TV and it still won't find any wireless networks. I suspect the wireless card in the TV has failed.
I also have a UE40ES5500 TV and that suffered the power cycling issue. We paid to have that fixed, but then over time found that Amazon Prime, Netflix etc were no longer supported and the apps were removed from the TV without any warning. We bought the Smart TV for those services and similar services and to find that within a year or so, services were just removed is appalling.
I suggest that someone from Samsung contacts me to explain or resolve the issues above, because as it stands at the moment I do not rate Samsung build quality, longevity in service, or customer service highly at all. I will not buy any Samsung products again - that goes for TVs, consumer products, mobile phones, tablets or PCs. Someone at Samsung needs to realise that these are expensive items and the fact that they just fail after a year or so in service is not good enough. They seem to treat these items as disposable items with a working lifespan of 1 year.
Further explenation of the above as I spend few good minutes looking for button on teh back of my TV LOL
Enter on remote controle while the TV is switched off
If that code don't work please try
Will take you to service menu. scrol down to second option and than press arrow right, you will see that you need to change your wiFi area to letter A
if this doesn't work try updating Firmware
if that doesn't work connect tv with cable to router
if you don't like teh idea of the cable you need to buy new TV as this one will cost more to repair than new one to buy
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 :-).
Hey, I have the model UE43NU7025, I press the "info" "menu" "mute" "power on" while the TV is off but nothing happens, am I doing something wrong? or is there another way to check the wifi region in this model??
I have two remotes with the TV. The fancy silver metal one with the track pad I hardly use. It doesnt have the same buttons anyway, so this was done is on the standard remote mine came with per pic below. Ensure TV is in standby/off first for a few secs. Then ensure that remote has clear site and pointed at the tV. Press the buttons in seccession per below not together, which would be hard to do anyway :-).
When I pressed the last one for power back on again up came the blue diags menu top left of screen on whatever I was watching, as mentioned. If not working for you I notice not exact same model as mine. I am in the UK, if you are not it may be a regional difference but if same remote you would think this is the same sequence for all the same model range, so as not to complicate things for their own engineers, although language difference may mean buttons and remote different layout in other coutreis of course but presumably just labelled accrodingly to language to standardise things also:-)
Pic for info: -
Hey there, thank you for taking the time to help! My remote is very similar to yours, but not the same, and so when I do try that button sequence nothing happens, the TV just turns on as it would normally.
I'll leave a pic of my remote in here anyway in case anyone knows how to get to the wifi region menu!
As yours is not a smart tv by the looks of the remote, have you also tried the other sequence that Tommy24 suggests:-
this has to be entered on remote control while the TV is switched off:
