When I first set up my Smart TV it connected to wifi straight away. The next time I turned it on it still recognised the wifi but couldn't connect to internet. I tried it with a wired connection which worked first time but again, the next time I turned on the TV it can't connect to the internet. I am with BT using their Smarthub. I've tried changing DNS to 18.104.22.168 and 22.214.171.124 but no change. Please help.
