Right I managed to get the 120 to connect too 02 and could connect it to a laptop and it worked.
However as soon as I connected to wan 1 on the 2920 the router wouldn't get an ip address from the 120.
The 2920 wan1 was setup as Ethernet and dynamic ip so it should have worked.
After hours of messing I gave up and used the 02 supplied modem which worked the instant it was plugged into wan1 on the 2920.
So why won't the Vigor 120.
Both are running the latest firmware so what is happening here???? What have I missed???
I used the settings here for the 120 http://www.draytek.co.uk/support/kb_vigor100_setup.html

Guess no one knows.l

did you set up the 120 for MPoA? If so and it's still not working right, check the firmware, I've seen 3.2.4.1 do weird stuff like what youre describing.

when using the 120 on another router the routers wan link should be set to PPPoE, not ethernet. Your ISP username & password would then be set up on the 2920.
