Thanks Ryan. I was actually expecting 2 FAIL and 4 PASS (and 1/6 PASS obviously), so it's good to know that it's the other way around. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/b

@christopherarges Cool, thanks! @all Can whoever had this issue with 3.0.0-15.24 please use this and check which of the 11n_disable=1,2,4,6 options helps? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https:

Yes I think it would be more interesting to test this on the 3.0.13 (or so) that others are using already, we just recently had some bugfixes in 3.2-rc that wouldn't have propagated up yet. The interesting thing would be having 3.0.x broken, fixed with 11n_disable=1 and then figuring out if it's a

@Chris, thanks! Is that really 3.2-rcX as the version indicates? @Ryan, did it work before with 11n_disable=1? I think we had some *new* issues with some other 11n APs newly introduced in 3.2-rc that we're just fixing now... -- You received this bug notification because you are a member of Deskt

I have just attached a kernel patch, I'd appreciate if somebody could try it out. This patch was prepared against 3.2-rc kernel, and parts of it (the changes in the iwl-mac80211.c file) will not directly apply to older kernels as we moved some code around. Those parts should apply to iwl- agn.c in

This bug is insane. I tried to make some sense of all the comments, and there are *at least* three unrelated problems ... Problem #1: "my skype connection is randomly interrupted and using wicd fixes it" This is likely caused by background scanning not going as smoothly as you think -- I believe
