Networking issues in Intrepid
Posted on December 8th, 2008 at 16:37
After my upgrade to Ubuntu 8.10 (Intrepid Ibex) I had been experiencing a number of network-related problems. Yesterday I was able to fix them.
The symptoms:
- When I booted without network connectivity the machine would hang (approximately 90 seconds) while doing "Configuring network interfaces".
- The Network Manager icon was not shown even though nm-applet was running.
- New wireless networks were not detected but existing wireless networks did work.
Fortunately these two bugs helped me to diagnose and solve the problem. I still had some old entries in my /etc/network/interfaces file which were conflicting with the new Network Manager. Apparently the file was not cleaned up during the upgrade.
I removed all lines in /etc/network/interfaces except the following two and all problems disappeared:
auto lo iface lo inet loopback
This happened to me too. Thanks for sharing the fix. It seems like every time I do an upgrade I always run into problems like this, as opposed to when I do fresh install.
I'm actually still having problems with NM when connecting via wireless WPA network. It eventually works, but it takes for ever. I didn't have this problem with hardy.
