Samsung UE46ES8000 wifi suddenly not working


I’ve got a Samsung UE46ES8000, which I bought back in 2012.
It’s usually fine, works faultlessly.

Suddenly, the wifi stopped working.

If I went to the network settings screen it would constantly fail to pick up ANY wifi networks (not even my neighbours)

I reset my router (just in case) – no avail.

Eventually, I stumbled across some posts online that suggested to do the following:

  1.  Enter the service menu. To do this, put the tv in standby, then press the following buttons: info, menu, mute then power (quickly)
    (see video at end of this post)
  2. In one of the menus (I don’t remember which) change the wifi region to A
  3. Reset the smart hub (in another menu option)
  4. SVC – reset

This worked for me!
