The long and short of it is NO it doesn’t. That doesn’t mean you have to stick with 2.4GHz for your entire network though. Just buy another cheap router and set it to 2.4GHz and hard-wire to your main router which you can set to 5GHz.

Add your systems / laptops whatever with a preferred wireless network to your 5GHz SSID and should that not be ‘visible’ add to your list the 2.4GHz SSID – DONE

This means that all your computers / consoles that can use 5GHz will use it, and for those that can’t will connect to your other router on 2.4GHz.

Simples. 🙂
