I have the same problem for more than one year. Sometime I even felt a little disappointed about Linux (This not only happened under Ubuntu, It happened under some other distributions too, for example, Arch), especially when I was having a meeting and wanting to show something to the professor over ssh: the network just dropped out every minutes or just can not connect.
Back to about two years ago, I used Ubuntu 10.04, there is no this problem. I switched to then newer 11.04 because of a problem with the display card driver, then this problem started to occur. I goggled and tried every workaround I found (I even bought a new network card), no one can completely solve the problem. I can connect to my home network without a problem, but when came to the campus network, many problems happened: I can connect to it in my office with several dropouts a day. I can not connect to it or the network dropped out every minutes when I was in a professors office, which is in the same building but on a different floor, and can not connect to it in the library in the same building . I kept installing new versions of Ubuntu and upgraded to new kernels, but the problem is still here. >From the output of dmesg, I noticed that there were usually two cases: 1. authentication timed out. 2. deauthenticated from the network quickly after a successful connection by local choice with reason number either 2 or 3. I don't think this is overcrowd related, because Windows works, iOS works, and even wicd works(not perfectly). And this also happens on another Ubuntu laptop of one of my office mates. -- 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: NM fails to connect to campus Wi-Fi network; wicd succeeds -- Centrino Ultimate-N 6300 iwlwifi To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/924082/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
