Samsung UE43TU7100 not connecting to internet

[L129]

Hello,

Our  Samsung UE43TU7100 has stopped connecting to the Internet.

We have reset all of the settings but it is not finding any networks. Has anyone else experienced this issue?

Yes. Samsung won't get another penny from me.

The only way to get it to work is to.use it as adumb tv and plug in a roku stick. What a fail.
