[Bug 836250] Re: [Oneiric] [Regression] Intel Corporation Centrino Ultimate-N 6300 poor networking, packet loss and very slow Lenovo X201 and T500 laptops
I went back and did some testing on 3.2.0-30-generic and 3.4.0-030400-generic from the mainline PPA (both AMD64) and my results are the same as I mentioned in #158. With the Linksys e3000, I get very good performance and with the Buffalo WZR-HP-G300NH router, I get unusable performance. Both routers were operating in mixed bgn with mixed WPA/WPA2. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/836250 Title: [Oneiric] [Regression] Intel Corporation Centrino Ultimate-N 6300 poor networking, packet loss and very slow Lenovo X201 and T500 laptops To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/836250/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

The variability of this problem is wicked.On a whim, I swapped out my Atheros AR9132-based AP for a Broadcom based Linksys E3000 and my N performance is much better now.

With the router operating in N mode the connection is stable and performance is very good. When I switch the router to B/G/Mixed (no N), the connection is stable but the performance is bad as noted in #54/55. I tried with 2 different routers (Atheros and Broadcom based) with the same results. So my experience is as follows. Sometime after 2.6.38-11 and before 3.0.0-12, G performance took a turn for the worse and is almost unusable even with 3.1.0.

Moritz, are you still using 11n_disable=1 with WICD? I suspect there might be two problems here. The first problem being N not working correctly. You can find the 11n_disable=1 trick documented for numerous distros. Based on my testing with Fedora 16 beta and the mainline 3.1 kernel in 11.10, this seems to be fixed in a later version of 3.x. The second problem is bad performance with G which doesn't seem to be happening with other distros and might be related to NetworkManager. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/836250 Title: [Oneiric] Intel Corporation Centrino Ultimate-N 6300 poor networking, packet loss and very slow Lenovo X201 and T500 laptops To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/836250/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
