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 On Jul 7, 2017, at 2:34 PM, Maykel Franco via arch-general wrote:

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??
