I talked my brother into installing Ubuntu via Wubi. He lives several thousand miles away, so I knew I wouldn't be able to help with his winmodem. He bought and installed a Linux compatible modem. He isn't able to get it working, however. I believe his problem is that he didn't uninstall his winmodem and there is a compatibility problem. I had him try different ports but no luck. Does he need to uninstall the winmodem?
