Hi All,

I saw a few threads about reduced performance in b43 in the 2.6.24 /
2.6.25_rcXX kernels, but couldn't manage to fix the problem myself:

On my system, using ndiswrapper and the windows drivers gives me about
1.5 times the performance of the in kernel b43 drivers.

Here are my system specs:

    Broadcom Corporation BCM4312 802.11a/b/g [14e4:4312] (rev 02)
    Linux 2.6.25 (gentoo-sources-2.6.25-r1).
    b43 wireless driver with firmware 410.2160 (2007-05-26 15:32:10)

I measured the performance by running "ttcp" between my Laptop and my
router. Using b43 on my Laptop gives about 2MB/s reported, and using
ndiswrapper gives me about 3MB/s under exactly the same situations.

Any ideas about what's going on? (I would be happy to provide you with
any further specs on my computer).

Thanks,

GI
