Comment 1 for bug 297422

I have a Dell Studio Hybrid with the same BCM4328 and suffered similar issues with the wl driver. The killer for me was that wireless would simply drop out for minutes at a time, then come back.

I grabbed the latest Broadcom driver (5.10.27.14) and dropped it into linux-restricted-modules-2.6.27-11 and rebuilt. It appears that this driver does not cause the drop outs any more. It still seems to miss some beats when streaming at high bitrates, but nowhere near as bad as it used to be.
