Probably if you could give me details on how you connect to the network in Windows ( As in User authentication/ direct connectivity/ Client login ). I could be of some help.

If in case your service provider requires you to install a software to get connected, we’ll have to look for a work around for that in Ubuntu.

I remember finding equivalents to Beam Cable’s 24online client a few years back. But You Telecom, I’m not really sure. Shouldn’t be a big deal though
