Hi lloydsmer
A simple test would be from diagnosis, ping diagnostic, IPv4, ping through wan2, bbc.co.uk once logged into Draytek
You should get 4 good replies and no lost
This confirms a few things, firstly you have a working broadband connected to wan2, and secondly dns is working
If the above fails, I suspect your second broadband is not working, so if you plug in your supplied router from isp, then hook a pc up to this router, can you ping BBC.co.uk or browse the Internet
If yes, then check your settings in wan2 on Draytek
There's more but need more details to help
Many thanks
John
