Hi @ranger55 Other ideas are , switching off Tv for a minute, factory reset and rebooting router. Another possible solution is to change the DNS settings. Go to Network-Network Settings-DNS Settings. Change from Automatic to to 184.108.40.206 or 220.127.116.11. (Google servers) or 18.104.22.168 or 22.214.171.124 (Open DNS)
