Bradley thanks for all. I install the broadcom-wl-dkms and later, pacman -Syu and add dkms module in the kernel. Now the wifi is more efficient, speed and stability. Thanks for all. T 2017-07-07 23:29 GMT+02:00 Bradley Klee via arch-general <arch-general@archlinux.org>:

Hi Maykel,

Don't confuse me for an expert, but I have been dealing with Broadcom issue on a recycled dell laptop.

According to the wiki, Broadcom devices have been historically difficult for Linux developers to work with. Replacement hardware could be a better option, but in the meantime wireless seems to work in my case using the "dkms" package.

If Installing this you should read the following:

https://wiki.archlinux.org/index.php/Dynamic_Kernel_Module_Support

Adding a dkms package will change your update procedure, sometimes making additional work for pacman.

In case you didn't find the MacBook-specific wiki page, which also mentions Broadcom issues, try looking around here:

https://wiki.archlinux.org/index.php/MacBookPro11,x https://wiki.archlinux.org/index.php/MacBookPro7,1

Also, this topic is on numerous BBS threads, so you may want to try a google search, such as: "broadcom macbook 4331 site:bbs.archlinux.org" .

Hope this helps,

Brad

Hi, I have install archlinux in my MacBookPro with this wifi hardware:

Broadcom Limited BCM4331 802.11a/b/g/n

In the wiki arch:

https://wiki.archlinux.org/index.php/broadcom_wireless

BCM4331 noticed to have problems with b43-firmware-classic. Use b43-firmware for this card instead.

I probed with b43-firmware-classic community and b43-firmware yaourt and both poor performance... 900k bandwith and microcuts.

I will try broadcom-wl because I see in this link:

https://www.reddit.com/r/archlinux/comments/5qlyfm/cant_get_wifi_with_broadc...

Too I see broadcom-wl-dkms but I have the default kernel no dkms.

Somebody with the same problem??
