I can see you only just migrated across today @Luckybob28 - try rebooting your router and it may come to life. If not, you'll need to wait until tomorrow morning to raise a fault, as it can be any time up until midnight that the service is activated.
If channels don't play at all in the morning then the best thing to do would be to call the helpdesk. There are a number of tests that can be performed whilst you're on the phone, before the fault is then passed to a team who can check the configuration across the network to see where the TV signal is going missing.
Don't call today though, as it's not possible to raise a fault on activation day.
There's no need to reset anything again though - it won't help. Just turn the power off and on at the wall socket.
