[Bug 663298] [NEW] No wifi connection possible at all (neither n nor b/g) with intel centrino wireless-n 1000

Tue Oct 19 14:15:07 UTC 2010

Public bug reported:

After upgrading to Ubuntu 10.10 my wifi card (Intel Centrino Wireless-N 1000) stopped working. NetworkManager (and 
airodump-ng) show me lists of networks and NetworkManager can try to connect to one, but it never finishes to connect.
dmesg indicates that there is something wrong:

[  120.616099] wlan0: direct probe to 00:27:0d:09:be:d1 (try 1)
[  120.816053] wlan0: direct probe to 00:27:0d:09:be:d1 (try 2)
[  121.016064] wlan0: direct probe to 00:27:0d:09:be:d1 (try 3)
[  121.216176] wlan0: direct probe to 00:27:0d:09:be:d1 timed out

This block of messages is repeated until I stop trying to connect. It happens on multiple networks, I tried it on n and b/g networks, encrypted with WPA2 and without any encryption at all). The messages are always the same.
After collecting the information for this bug report, a more informative message popped out of dmesg:

As i said, this behavior only appeared after upgrading to Ubuntu 10.10. However, I could _not_ get the wifi to work by booting Ubuntu 10.04.1 from a Live-USB-drive. I also tried the mainline kernel corresponding to my current kernel version (mainline kernel 2.6.35.4) which didn't help.
Windows 7 x64 Prof. on the same machine can connect to wifi networks just fine, so the error does not seem to be hardware related.
As long as this error persists, I cannot use my wifi card at all.
