Network problems (wired and wireless) after upgrading to Feisty

Asked by Suraj Acharya on 2007-04-25

After upgrading to Feisty I've run into this problem where the network manager applet is constantly rotating with one green light. It does this even when trying to connect to my wired network. However I can still connect to the internet. Network-manager seems to reset the connection very frequently though, this is not an issue when connected to the wired network, but it asks me for the wireless password every minute or so.

Here's a snippet from my /var/log/syslog:

Apr 25 14:20:11 sacharya-laptop dhclient: DHCPRELEASE on eth0 to 192.168.42.1 port 67

This cycle of the the dhcp transaction timeing out continues forever. However, as I said earlier, I can connect to the network while this is happening.

You have somehow multiple dhcp processes on the eth0 interface running. I would kill all of them and then restart the network with

sudo /etc/init.d/networking restart.

I hope this helps.

I tried killing the processes, but network manager seemed to spawn a dhclient process right away. So I killed NetworkManagerDispatcher and NetworkManager, then the dhclient processes. and then ran "sudo /etc/init.d/networking restart" and started the networkmanager processes. Still no luck, the behaviour looks the same to me.

Could you please run this command

dpkg-query -l 'dhcp*'

and post the output that we can see which dhcp package is installed.

Thanks

Synaptic doesn't seem to think that there are older versions of these packages around, or I'd try to go back to an earlier version to see if that fixes anything.
