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.
- Reboot
All being well you should have network-manager running, with a live network connection.

After thinking about this a bit, I’m pretty sure it was a problem with the way i was installing Ubuntu. Both me and my work mate were booting off a live CD over the network. Oh well, I hope this is of use to someone.
I booted off of CD and had the same issue, however the above fixed nice one 🙂
As a Newbie, I am always browsing online for articles that can aid me. Thank you
Tested Ubuntu 10.04 Live CD. Internet and network detected, wireless not, but figured I could tackle that later. Installed to HDD. No network card detected. Tried inputting MAC, SSID, etc. with reboot each time. No dice. Tried above, but no mention of eth0 on my system. How can a Live CD work and the actual install not?? Seems weird. Any ideas?
