Hey guys. So, I have a new iMac and a new MacBook Pro both of which support 802.11ac. Naturally, I'd like to take advantage of this so I bought a new AirPort Time Capsule to go along with them. I've noticed a couple times now that the iMac and the MBP seem to be secretly defaulting back to wireless-N on the 2.4 GHz band. Is there any way to force them to stay on wireless-AC on 5 Ghz? One thought is that my XBOX 360 uses wireless-N only and so maybe all the other clients are defaulting to N? Is there any way to make my new Time Capsule for AC clients only and use my old Time Capsule for all other clients only? Thanks!
