I have exactly the same problem with exactly the same wireless card / driver and exactly the same outputs.
What happened is that until 8.04 I upgraded and I had a eth1 in my ifconfig, now that I reinstalled from scratch, I have a wlan0, so I supposed to have upgraded from ipw3945 to the new iwl3945 drivers Until then (i.e., when I was using eth1, i.e. ipw3945) everything was fine; I even do not use NetworkManager, but I configure from command line using ifconfig / iwconfig (and killing NetworkManager if it's active) I think that the most important thing is the dmesg log that says: [ 49.256926] wlan0: associate with AP 00:0f:b5:cd:08:84 [ 49.259121] wlan0: RX ReassocResp from 00:0f:b5:cd:08:84 (capab=0x461 status=0 aid=1) [ 49.259136] wlan0: associated [ 49.262119] wlan0: disassociating by local choice (reason=3) let me know if you need more from me; I also tried the backports -- intel 3945ABG with driver iwl3945 [intrepid] doesn't connect https://bugs.launchpad.net/bugs/291685 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
