Sorry -- there's just really nothing in that bug report that supports this. If you can, please test with a different card or whatnot, but there's still no reason to believe a success might then be because it's the different card. Didn't you mention you sometimes successfully connect?
Stating the description: "when I can connect, the connection is flawless. But very often I cannot. The connection is generally worse in crowded areas, or areas with many access points." With the additional information that it's usually worse in crowded areas or when there are many access points (many access points is generally indicative that the area may be crowded to a point that multiple APs are required to support all the clients), it's further evidence that this is just contention on the AP side. There are however known problems with N on this kind of card, so I guess it's technically possible you'd be seeing a different side-effect of the performance issues with N -- but you also mentioned this was different from the other performance-related bug reports. Finally, this being the only network where you reportedly encounter this particular issue, there is again then no evidence to suggest it's not environment-related. I'm willing to consider this might be a bug in NM, but those would normally affect all wireless networks indiscriminately considering NM only asks the kernel via wpasupplicant to establish connections and does minimal house-keeping for the connection. Everything else is done by the kernel. I'll reset this to Incomplete. Please see if you can provide further information that would point this clearly in the direction of a software bug. ** Changed in: network-manager (Ubuntu) Status: Invalid => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/924082 Title: Intel Centrino 6300 Cannot connect direct probe timed out To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/924082/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
