I am running Ubuntu 12.04 and use Firefox as my web browser: I am also using Windows XP with Firefox as my web browser. I am trying to pension off the Windows machine and get all my programs to run under linux but whenever I go on-line with the linux machine no matter what I am doing, after a short time I get a "can find server at xxx", then if I click on the "Try Again" button it sometimes finds it after a few seconds and other times takes me back to the error message.

My connection is via satellite (NBN Co) so this could be the the problem but the Windows machine sitting beside it and using the same LAN seems to have no problems.

I would greatly appreciate any help or suggestions.

cheers all
