Internet not working after midnight

[Quilter68]

Why does my internet stop working properly after midnight? Some sites work such as Google but most others won't load. I don't have any parental controls on. Using a different DNS server works but only on the devices I can set it on.

That would indicate a BT DNS server problem. Try 1 reboot of the hub, you may pick up one of the other BT DNS servers.

We tried restarting numerous times and it doesn't work.
