Following the instructions on your support pages I successfully configured my Vigor 120 for BeThere, but from the point when I connected to the internet, I could no longer access the modems admin web interfaces at http://192.168.2.1. Should I be accessing via another address? or is there something wrong?

you can only access it via direct connection i had same problem basicly i set up first the 120 then connected it to the vigor 2830 it worke for me fine aok connection
