WLAN connection not being picked up after hibernation

Bug Description

Quite frequently my laptop fails to reconnect to the wireless lan after waking up from hibernation.
Sometimes the network manager applet shows the network signal level indication bars but there's no connectivity, sometimes the applet shows the "connecting to network" indication but connection is never established.
Sometimes after hibernation I get the keyring password prompt and the system is able to reconnect just fine.

I'm using Ubuntu 7.10 with all the latest updates on Dell Latitude D620.

aspa@aspa-laptop:~$ dmesg|grep ipw3945:

I switched to the iwl3945 driver but i'm still seeing the same symptoms.
The issue seems to appear when the system goes into hibernation in one network and wakes up in another.

Is this symptom still reproducible in 8.10?

Unfortunately I don't have the machine anymore. It's also not possible for me to install Ubuntu on my current machine.
