I'm looking to get a new computer for someone and am trying to understand 802.11ac. It only runs on 5GHz according to everything I've seen, so my question is, can it connect to an older router that only works on 2.4GHz (like a Linksys Wireless-G router)? Can the 802.11ac PC use 2.4GHz to connect, say at a slower speed like N? Or would the 802.11ac client be incompatible with a router that only works on 2.4GHz?
If this is a dumb question I apologize, but I can't find a straightforward answer anywhere. Thanks.
