2wire home portal works out of the box with linux. I recently changed my router but I still have the 2wire home portal and works flawlessly with any linux (not just dual boot but quad-boot). Can you tell us what steps you followed. The 2Wire home portal uses dhcp to assign ip address to the client so it may be possible that it hasn't assigned an ip address to you.
Try out this command first report the output here:
When I try to connect directly with the 2Wire setup, all I get is a 'connection refused' message.
How did you try to connect??? I would suggest you open up your browser and enter
All you need to manage 2wire portal can be done through it.
BTW, I've used 2Wire home portal with SuSE, Debian, Ubuntu, Fedora, Slackware, Red Hat, Arch Linux.
Hope this helps,
