Ever since I updated to latest security update I couldn't use the wireless compat modules from http://wireless.kernel.org/. So, with the regular modules, If I watch a video from an NFS mount on my network, I'll loose the wireless connection. I have to disable and then re-enable wireless to gain a working connection again just to loose it in a minute or two. Same happens with the linux-backports-modules-compat- wireless-2.6.36-maverick-generic.
As a workaround I add "radeon.modeset=0" the the kernel I'm loading on grub. That makes the connection pretty dam stable, so far no wireless connection lost, event watching that video from the NFS mount. $ lspci -vnn | grep -A 1 Wireless 05:00.0 Network controller [0280]: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection [8086:4222] (rev 02) Subsystem: Intel Corporation PRO/Wireless 3945ABG Network Connection [8086:1001] Flags: bus master, fast devsel, latency 0, IRQ 45 $ uname -a Linux lgl 2.6.35-27-generic-pae #48-Ubuntu SMP Tue Feb 22 21:46:58 UTC 2011 i686 GNU/Linux -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/621265 Title: Slow Wireless Connection in Intel 3945abg -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
