Nearly every time my daughter switches on her tv it doesn’t connect to our WI-FI. EG the YouTube button doesn’t work regarding connecting. To do it we have to go into the settings and network and then press the WPS button on the router and it finds it. We don’t have to re enter the password. Checking on the net it’s suggesting the firewall? Is this correct and if so, can I stop having to keep doing this? Sick of going up stairs to sort it! I can’t seem to find how. The other tv’s do not do this, which made me think it’s not the firewall. Help appreciated.
