with 2.6.34-rc4, the symptoms are exactly the same: on boot, the association appears to succeed, and on the router I can see that an IP address is being allocated to 00:0c:f6:37:be:29, which is the macaddress of wlan0. But this IP address, although distributed by the server, is never allocated on the client.
I can see in daemon.log: Apr 30 12:41:51 pixie wpa_supplicant[607]: Trying to associate with 00:1d:7e:c6:9c:24 (SSID='WRT-AS24' freq=2412 MHz) Apr 30 12:41:51 pixie wpa_supplicant[607]: Association request to the driver failed And syslog shows messages like: Apr 30 12:43:36 pixie kernel: [ 670.015997] ===>rt_ioctl_giwscan. 5(5) BSS returned, data->length = 677 Apr 30 12:43:36 pixie kernel: [ 670.016588] ==>rt_ioctl_siwfreq::SIOCSIWFREQ[cmd=0x8b04] (Channel=1) Apr 30 12:43:41 pixie kernel: [ 675.341534] ===>rt_ioctl_giwscan. 6(6) BSS returned, data->length = 853 Apr 30 12:43:41 pixie kernel: [ 675.342073] ==>rt_ioctl_siwfreq::SIOCSIWFREQ[cmd=0x8b04] (Channel=1) lad...@pixie:~$ uname -a Linux pixie 2.6.34-020634rc4-generic #020634rc4 SMP Mon Apr 19 09:38:39 UTC 2010 i686 GNU/Linux lad...@pixie:~$ iwlist wlan0 scan wlan0 Scan completed : Cell 01 - Address: 00:1D:7E:C6:9C:24 Protocol:802.11g ESSID:"WRT-AS24" Mode:Managed Channel:1 -- rt2860 cardbus can't connect: Association request to the driver failed https://bugs.launchpad.net/bugs/564629 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
