again BT DNS server not working correctly. Some of the websites not openig.
To get all you website opening you need to change the DNS settings.
I'm using opendns 220.127.116.11 and 18.104.22.168
It's working fine for me. When I've had problems, I can usually fix it by rebooting both the Home Hub and the PC.
Don't forget to go back to BT DNS server (Automatic) in case the DNS your using at the moment stops working correctly in the future
Why use BT's DNS servers at all? It is totally unnecessary. You don't need openDNS as your secondary server.
You could have OpenDNS as primary and Google as secondary or visa versa.
