Hello,
I have been using the wireless connection (Intel 3945 a/b/g) on my Dell e1405 running Hardy 8.04 for months now without problem. In my house, I either connect to my router through wireless, or where the connection is weaker, I use a direct wired connection to use the network.
Sometime in the past few weeks, the my laptop has become unable to connect to the network through wireless. I can't pinpoint the exact date and time, because I often switch between wireless and wired, and I also sometimes boot to the Windows XP partition on my laptop (and on that partition, wireless networking continues to work).
Based on other forum posts here, I observed that my network adapter was not being enabled:
$ dmesg | grep -i wlan
[ 54.654498] ADDRCONF(NETDEV_UP): wlan0: link is not ready
I confirmed that the kill switch was not disabling the wireless. I attempted installing a new driver:
sudo apt-get install linux-backports-modules-hardy-generic
... and that succeeded in lighting the WiFi LED, but still Network Manager refused to show or connect to any wireless networks.
I did:
sudo rmmod -f iwl3945
sudo modprobe iwl3945 disable_hw_scan=1
sudo iwlist wlan0 scan
sudo su
echo -e 'alias wlan0 iwl3945 \noptions iwl3945 disable_hw_scan=1' > /etc/modprobe.d/iwl3945
reboot
And scanning works, showing me my access point, but still no wireless networks appear in Network Manager, and I am still unable to connect to any wireless networks.
Finally, I uninstalled and reinstalled Network Manager:
sudo apt-get purge network-manager-gnome
sudo apt-get autoremove
sudo apt-get install network-manager-gnome
Still no luck.
Was there a recent software update that affected wireless operation? Anyone else experience the same scenario, where wireless worked and then ceased to work?
Thanks.
