[SOLVED] Extremely Slow Wireless on Macbook Pro

What Wilco said up above there might have been right all along.
I dumped the output of `lsmod` with both my old and new kernels. With the old kernel, bcma would never load, and internet worked wonderfully.
With the new one, however, bcma is loaded automatically, and if blacklisted, all wireless functionality is lost.

I'll going to give broadcom-wl another go. If it works, we ought to update the Wiki.

Alright, it's all fixed and working. Using broadcom-wl. Wireless speeds are as fast as they've ever been.
Time to go write up how I did it.

fosskers, thanks so much for this. It solved my problem right away.

I'd like to remind anyone trying to follow the steps that you need to have compatible versions of the kernel and headers as the package broadcom-wl requires kernel headers.

If you into trouble in the build step of the broadcom-wl package, you might need to

# pacman -Syu

to update everything.

For the sake of comparison here are speed tests before and after the firmware change from b43 to broadcom-wl:

fosskers, thanks so much. This solved my problem on my Macbook Pro Retina (Mid 2012) with the BCM4331 Network controller.

At work it was so bad I was dropping 50% of the packets.

I'm here to confirm this solution is not too old, even in 2016.

I'm glad the solution still works, but please don't necrobump, charlespwd.
