DCHP problem on ethernet - brand new Hub 3.0
We recently joined Virgin 2 days ago on M500 with a Hub 3.0. Anything that is connected with ethernet will not connect to the internet. Was working fine day one, however now getting error "Can't connect to DCHP servers" on all devices that use ethernet. I've tried multiple ethernet cables, different ports, restarting router etc nothing is working. I'm at my wits end here, was excited for fast broadband but this is disappearing! Hoping someone here can help as I just spent 1 hour 20 minutes on the phone and got nowhere! Thanks
