I've got a problem with the Smart LED 37PFL7606H/12 which doesn't connected wireless with the router.
Just upgraded the tv to the latest version using a LAN cable but this wasn't the problem.

The router is aproximely 5 metres away from the tv so the distance doesn't cause the problem.
The laptop and playstation are connected wireless so i'm guessing the problem had something to do with the tv itself.

Is there any known way that problem could be solved?

Thanks in advance
