[arch-general] Poor performance wifi BCM4331 - MacBookPro

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??
