I'm hopeful that the driver was simply updated between April and June and that now BCM4360-based wifi adapters can run at 802.11ac speeds, but as it's closed source, I can't check the commits, and have not been able to find any discussion more recent than what I linked above.

Unfortunately, he doesn't detail what changes he made. On the other hand, this user (in a post from June) states that he managed to get ac speeds in Arch simply by changing his router settings. I have found user reports here and here from April 2014 stating that the driver runs BCM4360 based adapters in 802.11a/b/g mode and doesn't allow 802.11n and 802.11ac connections to be made. What I'm interested in learning is how a wireless adapter based on the BCM4360 will perform using the broadcom-wl driver-I don't want to buy a wifi adapter that won't work at its full capacity, after all. This leaves me with the proprietary broadcom-wl driver, which is listed as supporting the BCM4360.

Did you install the correct kernel headers with the dkms driver version If you must have a real time kernel, then I would use the newest RT kernel. chartrekhan: Ive tried installing broadcom-wl, broadcom-wl DKMS version, but those didnt work. The Broadcom BCM4360 chip is not supported by the b43 driver, and I believe it also isn't supported by the brcmsmac driver, since it isn't listed here. Broadcom bcm4360 - Wireless card not working. It is worth noting that every available 802.11ac compatible PCIe based wireless adapter seemingly uses this chip (I've heard of people having success with 802.11ac speeds using Qualcomm Atheros based wifi adapters and the ath10k driver, but there are no Atheros-based PCIe wireless adapters on the market, as far as I can tell).

The best candidate I've come across is the Asus PCE-AC68, and PCIe based adapter that uses Broadcom's BCM4360 chip, the same wifi chip used in the Late 2013 retina Macbook Pro. I recently got an Asus RT66U router, so I'm looking for a wireless adapter that supports the 802.11ac standard. I'm currently in need of a wireless adapter for my desktop computer.
