Bug Description

Binary package hint: network-manager

I have a T60p whose wireless worked fine in 8.04, but it's broken in 8.10.

On resuming after sleep, the network manager scans are not updated. Still tries to login to networks that are *not* present in the vicinity (i.e. the home networks when at work, and viceversa).

The only cure I've found is, on resuming from sleep, to killall and modprobe out and in again, and relaunch both NetworkManager and the nm-applet:

sudo killall NetworkManager wpa_supplicant nm-system-settings nm-applet

sudo modprobe -r wlan_wep
sudo modprobe -r ath_pci
sudo modprobe -r ath_rate_sample
sudo modprobe -r wlan_scan_sta
sudo modprobe -r wlan

sudo modprobe ath_pci
sudo modprobe ath_rate_sample
sudo modprobe wlan_wep
sudo modprobe wlan
sudo modprobe wlan_scan_sta

sudo NetworkManager
nm-applet &

After the above, wireless scans are proper and connections work fine.

Some information on my system:
