I have the same card, and I'm seeing the same problem. Using the current stock Ubuntu kernel, speeds max out at about 20 KB/second, no matter where the traffic is coming from (LAN or Internet.) If I recall correctly, this problem was noticed and fixed quite awhile ago by the bcm43xx team. The current version of the driver (as seen with a 2.6.20.4 vanilla kernel, and appropriate patches from the bcm43xx maintainer's (Larry Finger) site here: ftp://lwfinger.dynalias.org/patches/ ) is very fast- almost up to the speeds exhibited in windows. I believe that patches exist for everything from 2.6.20 through 2.6.21-rc5, and I also think that all of the patches bring the code up to the same level of performance.
I know the devs are flooded with work for Feisty, but this is a huge issue for anyone with a Broadcom card (which is almost everyone with a built-in HP or Apple wireless card) that seems (at least to my untrained eye) to be relatively easy to fix. If at all possible, it would be awesome for feisty to have decent Broadcom support out of the box (ignoring the issues with firmware- perhaps that could be addressed using the restricted drivers manager? I don't know.) -- Broadcom 43XX (4311) does not work? https://launchpad.net/bugs/94972 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
