As suggested in this bug: http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=2314 I reverted to the older microcode (iwlwifi-1000-3.ucode) and performance in G mode is quite a bit better, but still not as good as it should be. ** Bug watch added: bugzilla.intellinuxwireless.org/ #2314 htt

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,

I have a Intel Corporation Centrino Wireless-N 1000 (8086:0084) in a Thinkpad x220. In 11.04, I had good performance once I added "options iwlagn 11n_disable=1". With 11.10 i'm using the same configuration. The connection is stable, but the performance is noticeably worse. For example, I'm curr
