PC can't connect unless it has static IP

[angeljs]

We recently updated our broadband to Halo 3. For some reason, since the new plan became active, our PC's and some other devices connect, but with no Internet access. I have to set a static IP and input network details on each device before we can access any websites. This goes for both WiFi and LAN connections. 

I have searched for days for a solution and tried every suggestion I can find but nothing helps.

Try telling one of the affected devices to forget any and all network connections that you have setup then factory reset (not just restart) your hub and set the connection up again
