I don't use Wireless N at all because of other nodes on my network are not N capable. So I've kept my entire network G for the time being. So even without using N I had this issue.
Since reporting the bug, I have freshly installed 11.10 64-bit, with the updated options for the iwlagn drivers in options.conf. "options iwlagn 11n_disable=1" ** Tags added: oneiric ** Description changed: While upgrading 2 separate laptops from Ubuntu 11.04 to 11.10, one being a Dell E1505 with an Intel 4965 card, the other being a Dell 1545 with a WiFi Link 5100 card, both suffer from nearly null wireless speeds. Both computers will connect to the network just fine, however, wireless speeds are terrible. Connecting directly to router via Cat5E cable and disabling wireless results in normal speeds. Both machines had kernels upgraded to latest mainstream kernels, and problem persisted. I had to revert both machines back to 11.04. --- Architecture: amd64 DistroRelease: Ubuntu 11.04 InstallationMedia: Ubuntu 11.04 "Natty Narwhal" - Release amd64 (20110427.1) Package: linux (not installed) ProcEnviron: LANGUAGE=en_US:en LANG=en_US.UTF-8 SHELL=/bin/bash Tags: natty Uname: Linux 3.0.6-030006-generic x86_64 UnreportableReason: The running kernel is not an Ubuntu kernel UpgradeStatus: Upgraded to natty on 2011-09-02 (43 days ago) UserGroups: adm admin cdrom dialout lpadmin plugdev sambashare vboxusers + --- + ApportVersion: 1.23-0ubuntu3 + Architecture: amd64 + DistroRelease: Ubuntu 11.10 + InstallationMedia: Ubuntu 11.10 "Oneiric Ocelot" - Release amd64 (20111012) + Package: linux (not installed) + ProcEnviron: + PATH=(custom, no user) + LANG=en_US.UTF-8 + SHELL=/bin/bash + Tags: oneiric + Uname: Linux 3.0.6-030006-generic x86_64 + UnreportableReason: The running kernel is not an Ubuntu kernel + UpgradeStatus: No upgrade log present (probably fresh install) + UserGroups: adm admin cdrom dialout lpadmin plugdev sambashare -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/874777 Title: Intel WiFi Cards with slow connection speeds To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/874777/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
