using kernel 3.0 finally provides a useable system: Lucid 10.04.3 with kernel 3.0.0-8 with the internal WLAN-G adapter uses again driver ath5k and gives the same decent performance as with the other kernels.
However, with both WLAN-N sticks the driver is now carl9170, both sticks connect to the router with 300MBits/s, and both perform on the copy with 50-55MBits/s. The transfers have occasionnal drops down to zero rate, but recover. So far no lost connections. Looks like the carl9170 driver is much improved over the ar9170usb driver. Would backporting the driver to the old kernels be an acceptable solution? Note: The Fritz-stick has the annoying habit of first mounting as a 'self-install' device. Before the WLAN device can be used, I have to manually unmount the stick. Then it connects by itself. Can this be prevented? The TP-stick does no such nasty stuff, it comes up directly as a WLAN-N device. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/730229 Title: Very poor performance of wlan-N adapter under kernel 2.6.38 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/730229/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
