Red Hat Bugzilla – Bug 484645
Sometimes, NetworkManager needs to be restarted in order to get network connection
Last modified: 2009-10-18 17:55:24 EDT
Description of problem:
Setup: Dell laptop running Fedora 10 with all updates, connected to LAN via ethernet, using DHCP addresses. Sometimes, when the PC is booted, a "network disabled" status is shown in the NetworkManager Panel icon. I then try to disable network+enable network again, through the pop-up menu from the NetworkManager panel icon, but as soon as I re-enable the network, the connection is immediately set to disconnected again. The only way to get network connectivity is to restart the NetworkManager service: After this, around 10 seconds pass, and then the NetworkManager icon shows that a connection attempt is in progress; and finally, a network connection (DHCP address) is obtained.
Version-Release number of selected component (if applicable):
No way to systematically reproduce it. It only happens once a week, or so.
Steps to Reproduce:
1. Attach PC to network
2. Turn on PC; make sure that the ethernet link LED is on
3. Log in
NetworkManager icon shows a disconnected network, and disabling+enabling through the NetworkManager icon popup-menu doesn't work, even after many re-tries. NetworkManager seems to give up on the network immediately.
NetworkManager would try get an address, instead of immediately giving up.
I believe that this problem existed with Fedora 9, too.
Can you attach your /var/log/messages from after you've toggled Enable Networking once or twice? I'd like to see what NM says it's doing to figure out if it's a NetworkManager problem or something like a kernel driver carrier bug.

Another cut-n-paste from /var/log/messages; this time after a cold boot, after the PC had been turned off for around 17 hours

I believe this to be fixed by:
I don't have a Fedora 10 installation any longer (I have upgraded to Fedora 11 a while ago.)
I haven't seen the problem for a long time. We can probably consider this closed.
