This could be a complete red herring, but on the off chance that it's useful info:
I'm seeing this issue on an Ultimate-N 6300 in a two-antenna laptop (with only antenna terminals 1 and 2 connected). This configuration works fine under Windows, but causes high packet loss under Linux Mint 12. Could the issue possibly be caused by only using two antennas on a 3-antenna card? It's tempting to speculate that maybe the Windows drivers correctly detect this configuration, but the Linux drivers attempt to use all three antennas. I wonder if any commercial laptop manufacturers configure three-antenna cards with two antennas? I may try to see if I can install a third antenna in the laptop, either temporarily or permanently and report back. -- 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
