---- STILL WITH NO INTERNET CONNECTION
I'm using ubuntu 8.04, updated until (10.20.2008), with a motorola cable modem, for just one PC, conected by eth slot.
Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue for you. Can you try with the latest Ubuntu release? Thanks in advance.
