My laptop has wireless card Intel Centrino Advanced-N 6230 and I had a similar problem on some access points: connection could be established and worked but bitrate would be 1Mb with intermittent packet delays up to 1000ms which made SSH sessions almost unusable.
I tried to build the latest kernel but it did not help much. However downloading the latest firmware from the official website helped greatly - now uplink speed is reasonably high and stable and packet lag is much lower. http://intellinuxwireless.org/?n=Downloads -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/979371 Title: iwlwifi WPA/WPA2 connection slow to establish on Ubuntu 12.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/979371/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
