For people seeing better behavior after changing to WPA-PSK. I was having the same problem in my system in the wating room of my son's therapyst (which we visit twice a week). The router is configured to use WEP and the connection would drop almost immediately. For obvious reasons I can not change the router configuration (even though I should take the time to explain to them how insecure is WEP).
I found out searching for possile solutions on the net that adding the option "ipv6.disable=1" to my boot line works. Give it a try. -- 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
