Have a 55 MU6120 tv
My TV will not recognise that there is any wi -fi in the house now although it did after being returned when I had the problem previously and they replaced the wi fi card. All of the network settings on the tv say zero so I presume there is definitely no signal. I purchased a 5 year warranty when I purchased the tv which doesn't run out until 2023 and after a lengthy and difficult phone conversation it was supposed to be collected today for repair but that didn't happen and also why should I be without a tv again for over a week.
I have tried all the suggested resets but I am convinced that the wi fi card is corrupt again.
Frustrated to say the least
@Members Tom: Are you able to create a Hotspot on your mobile phone, and try connecting to it via Settings > General > Network > Open Network Settings > Wireless, to see if the issue persists? If it does, head to Settings > General > Network > Reset Network, then power off the TV, unplug it at the wall for 30 seconds, then plug it back in again and power back on. I'd also recommend applying the same power cycle steps to your router. Now, head back to Open Network Settings > Wireless > Select your router from the list of available networks, and attempt the connection once again. Let me know how you get on.
Have tried all of that to no avail.
When it first started playing up I tried to reset the network and it wouldn't even find any wi fi connections. The only reason I can watch anything is through sky go .
