Red Hat Bugzilla – Bug 212680
NetworkManager resume from hibernate unable to see wifi networks
Last modified: 2008-08-02 19:40:34 EDT
NetworkManager does not see any wireless networks after resuming from hibernate.
If I restart NetworkManager itself, "/etc/init.d/NetworkManager restart", the
applet is able to see the available wireless networks. I'm able to connect and
surf the web as normal.
This happens on both i386 (using i686 kernel) and x86_64. Wireless card is an
Intel 3945 with use of the modules from atrpms.net
Clemson Linux http://www.ces.clemson.edu/linux/suspend_mem.shtml detailed a
script (written under FC4) for NetworkManager to sleep during hibernate.
Perhaps this should be the default action in Fedora Core?
Tried that script and modified it to use pm-hibernate instead of echoing disk to
/sys/power/state but same results. Have to restart NetworkManager or recheck
Enable Networking in the applet.
I have the same problem on my Macbook Pro 15" using Fedora Core 6. I am able to
get onto the network if I restart the network service and then manually type in
the name of the access point. However, that seems unreliable and I usually
restart the network first and then both the network manager dispatcher and
network manager daemon, and then I wait a while and it seems to work sometimes.
Very unscientific, but I have had positive results.
Same problem with Thinkpad T41p. As far as I recall it did work (ie would
re-connect after suspend to disk) after FC6 was installed from the distribution
ISOs. But after a few "updates" it stopped working. My fix is to issue "ifconfig
wifi0 up" from the command line.
Re-connecting works for me if I restart the NetworkManager service, on a Vaio SZ3.
Same problem, Black Macbook 15". FC6.
I usually get around it by removing the modules, restarting networkmanager
service then restarting the applet.
I've noticed that the dbus-script, mentioned in comment #0, is already present
in /etc/pm/hooks/10NetworkManager, I can't tell but it looks as though its
already being run with no effect.
I'll do a full test with FC7T2 when it comes out.
Any progress on this?
I have upgraded my laptop to F7 and am unable to suspend or hibernate at the
Ok. Do we have another bug open for these other issues?
