After installing from a live CD where there was no problem with the network, I was supprised to boot a fresh install of Ubuntu 10.04 lucid lynx, with no network access. Fair enough, I thought probably just a one off, my PC. However after my work mate also had trouble with the network after a fresh install where the network was working on the live cd before hand I decided that something must be afoot.
Anyways this is how I fixed my network problem, hopefully it’ll help someone else!
- Edit /etc/network/interfaces and remove all traces of eth0 (remove both lines)
- My Network Manager had failed to start at all so to manage the network connections open up System > Preferences > Network Connections
- Add a new wired connection. I copied the mac address of my adapter in, although I’m not sure this actually matters. Click Apply and Save your new connection.
All being well you should have network-manager running, with a live network connection.
