On my machine, I seem to have temporarily stopped this problem, although by the lack of activity on this thread it may be that in more recent kernels the problem is already fixed.
lspci shows my wireless card as 03:00.0 Network controller: Intel Corporation Centrino Ultimate-N 6300 (rev 35) I am running Fedora 15 with kernel 2.6.43.8-1. First I downloaded the most recent firmware (9.221.4 ) for the wireless card from here: http://intellinuxwireless.org/?n=downloads&f=ucodes_6000 I unziped and untared the file and put the ucode in /lib/firmware. Then unload the kernel module rmmod iwlwifi and reinsert the module with bt_coex_active=0. modprobe iwlwifi bt_coex_active=0 For me, this lets me connect reliably(well, all morning) to a WPA2 network, which I couldn't do before. It connects at good wireless N bitrates, and seems stable. However, there are still large numbers of Tx excessive retries. Hope this works for someone else. -- 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
