Are you sure? Supporting 802.11ac in 2012 is pretty amazing considering that the standard was finalized in late 2013.

Oh, you're right. I was quite sure but it's indeed 802.11n. Maybe I thought it was an upgrade from the other systems (laptop and phone) I had at the time because it was the first with 5 GHz, seeing new WiFi networks that no other of my devices could see, and conflated that with the new standard. That's still faster than the internet connection I have and host my website on today, but not by as much
