Asus PCE-68 Wireless-AC Extremely Slow

Hi,
I'm attempting to get my Asus PCE-AC68 PCI-E wireless card going under Arch. Currently running kernel 3.14.2 with the broadcom-wl-dkms package installed from AUR. The card uses the Broadcom BCM4360 chipset, which I understand is only supported by the wl driver. The card is detected, and I'm able to connect to my router, but the link speed stays around 27Mbps according to the network manager applet. Additionally, I'm seeing:

 ERROR @wl_inform_single_bss : cfg80211_inform_bss_frame error 

from dmesg. I saw another thread that had the same error, but with no resolution. I'm happy to post any additional information to troubleshoot the issue. The card works at full speed under Windows 8.1.

EDIT: I suppose I should add that I have another wireless card in there as well. This is a 2009 8-core Mac Pro with the Apple Airport card that came with the computer, it's a BCM4321 card. Removing it seems to have no effect.

Re: Asus PCE-68 Wireless-AC Extremely Slow

Looks like I answered my own question.

I came across this thread here for a macbook air (which has the same BCM4360 wireless chipset) which puts the issue to rest. The current broadcom driver isn't capable of full AC speeds, and is in fact limited to G only. So the maximum speed is 54Mbps. Very disappointed by this, but at least we now know why it's so slow.
