It has been some time since I posted here, but I finally took the time to update to 12.04. I did a clean install and had the same slow Wi-Fi problem out of the box. So I can confirm that Bug #621265 affects Ubuntu 12.04 Precise Pangolin too. I then did the same change documented previously of removing NetworkManager and installing Wicd. All is working once again. All that said, this appears to not be a GNU/Linux, driver, or Ubuntu issue rather a Network Manager package issue since the bug is so easily fixed by merely replacing that package with a comparable one.
Here are the steps I performed: NOTE: Plug in a wired ethernet connection while completing these steps or reverse the order of the next two steps if one is not available. $ sudo apt-get remove network-manager $ sudo apt-get install wicd NOTE: To get the SysTray Icon to show up, you have to follow the tip from here: http://ubuntuforums.org/showthread.php?t=1762663 $ gsettings set com.canonical.Unity.Panel systray-whitelist "['all']" NOTE: Or for a more involved, probably more correct, way to get the SysTray Icon to show up, follow the steps here: https://bugs.launchpad.net/wicd/+bug/761326/comments/2 Reboot and log back in. You will have to reenter all of your saved network credientials, so it is a good idea to swap managers as soon as the need is identified. Just for the record, here is my upgraded system specs: $ lsb_release -rd Description: Ubuntu 12.04 LTS Release: 12.04 $ uname -a Linux bill-laptop 3.2.0-25-generic-pae #40-Ubuntu SMP Wed May 23 22:11:24 UTC 2012 i686 i686 i386 GNU/Linux $ lspci -vnn | grep -A 1 Wireless 06:00.0 Network controller [0280]: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection [8086:4222] (rev 02) Subsystem: Intel Corporation PRO/Wireless 3945ABG Network Connection [8086:1000] Flags: bus master, fast devsel, latency 0, IRQ 45 -- 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 To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/621265/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
