Wireless ac Help please

[smickoi]

Hey guys I just bought an ASUS RT-AC66U router and a ASUS PCE-AC66 wireless card,

Here's my problem, When logging on to the network both the wireless 2.4 and 5ghz are showing but they're both '802.11n',

I'm new to this whole ac thing but should they're be a '802.11ac' signal as well?

Set the router to work in wireless AC mode only, for some weird reason my N machines worked on G before i forced them, this is however a temporary workaround.

Yeah that's what I want to do but there's no option, the only options are auto, n only and legacy, bloody asus

How about the wireless card ?
