I am getting daily issues with the talktalk DNS servers and connectivity. Every day around 17:00 BST i suddenly cannot access web sites. It doesn't matter if I use Wifi or ethernet cable. I can ping the ip address of websites but as soon as you try accessing one I get an error. I've restarted the router to no effect. I have pointed other devices to Googles DNS and they seem to work. I can't do the same for my work computer without the admin access and I shouldn't have to.
