[CentOS] Dual Band Wireless

Hi,

Because of heavy interference in the 2.5GHz range in my neighbourhood, I 
want to switch to wireless dual band (5GHZ) and wireless ac.

Do you have any suggestions for USB wireless adapters for CentOS 6.5 
that work with dual band and ac?

Also, if you have any suggestions on wireless routers for these bands I 
would like to hear about them.

Thank you,

Joe
