network manager fails to find wireless network after suspend

Bug Description

Binary package hint: network-manager

For the last week or so, whenever I've suspended and resumed my laptop, network-manager has failed to pick up the wireless network again. I've tried '/etc/dbus-1/event.d/25NetworkManager restart' but this makes no difference.

I'm assuming this is a problem with network manager, but it could also relate to power management. Please let me know what I can do to help debug this.

I'm running the latest updated version of Hardy. 0.6.6-0ubuntu5.

Thank you.

For what it's worth, this is happening to me too. Dell D830, intel 3945 wireless card, latest hardy builds. It works fine after a reboot but after a suspend/resume, it's gone. This was working fine in earlier Hardy builds as well as Gutsy. Thanks.

This may be bug 183968.

Check the output of the command "ifconfig". If one of the entries in that output is named wlan0_rename or similar, it's almost certainly that bug and you can use the workaround listed at bug 183968. Please tell us what happened either way.

That was it (in my case, of course, unsure about the original submitter's). ifconfig was showing the interface as wlan0_rename (before the suspend; after waking up ifconfig didn't show wlan<anything>). Anyway, I implemented the workaround describe in 183968 and sure enough it fixed the problem. Thanks!

joss, are you able to tell us what the output of "ifconfig" in a terminal is?

Thanks for your help. Yes, I was suffering from bug 183968 ('wlan_rename').
After following the two steps noted for that bug, it's now been resolved.
