restarting network manager after suspend?

[high]

network manager doesn't see the wifi 3945 card after a resume from a hibernate but if i do "/etc/init.d/NetworkManager restart" it then picks up the wifi card and wireless networks available

edit: this is fc6 i686

You don't need to restart NetworkManager, just right click on the icon and uncheck "Enable Network" and then recheck it again.

However the real answer to your problem is to add the following lines into
/etc/dbus-1/system.d/NetworkManager.conf

<policy user="haldaemon">
               <allow send_destination="org.freedesktop.NetworkManager"/>
                <allow send_interface="org.freedesktop.NetworkManager"/>
        </policy>

This lets the user haldaemon (which is what hal runs under) talk to NetworkManager. You should probably restart dbus (or just reboot) and see how things go after a resume

unselecting the reselecting "Enable Networking" works. however the additional lines to /etc/dbus-1/system.d/NetworkManager.conf don't help.

created a ticket on redhat's bugzilla for fc6 https://bugzilla.redhat.com/bugzilla....cgi?id=212680

going to try the acpi scripts provided in that ticket now

actually you are right. What happened was in Core 5, the Network Manager wouldn't even see the firstless on first boot / login. That was the solution. in Core 6 at least for me this is not a problem without those linies

no one else encountering the same problem?

I had this problem in FC5 with my atheros card using the madwifi driver. Now in FC6 it's even worse. When I boot NetworkManager configures my wifi fine. I suspend and resume and now NetworkManager doesn't seem to know I have a wifi card at all. I can reload the driver modules, restart NetworkManager, dhcpbd or whatever, etc etc all to no avail. The only solution I've found so far is a reboot. I can't quite identify what the disconnect is. I can sleep and wake NetworkManger using the commands in /etc/pm/hooks/10NetworkManger and it immediately picks up the wifi again. I can talk to the card with iwconfig and list the APs with iwlist. So it seems like everything is fine but something is obviously goofed up.
