Tv can't connect to LAN and wifi

[Admire]

My Sony tv cannot connect to the wife. They recently replaced my router with a sky hub. Previously when the last engineer came he checked the wire to my tv. This engineer didn't and only replaced the sky hub in the hall way to the telephone point. My tv is not picking up the wifi says no LAN and no wifi

Typically you'd need to carry out a network reset on the television set before either reconnecting the ethernet or teaching it new WiFi credentials.
