Changing from 2.4G to 5G wireless network


I have a Linux box networked wireless to my LAN. As seen below, it is using 2.4G. I will be getting a new router (http://www.asus.com/us/Networking/RTAC68U/), and I have heard rumors that it might have issues on 2.4G, but works great on 5G. Am I able to configure the Linux machine to use 5G? Thanks

Code:
[Michael@devserver ~][Michael@devserver ~]$ iwconfig

Probably not - not all 802.11n devices can communicate on the 5GHz band. The channel list above tells us that this wireless chipset won't do 5GHZ, sorry.

The router should do both 2.4 and 5. I have a Netgear that does both, automatically. Some of my devices can't do 5, but connect fine to the 2.4 network.

Thanks gents (or ladies if I presumed wrong).

Router will do both, but not sure of the recipients.

If on the off chance 2.4 is sketchy, and the Linux machine can't handle, I assume I can fall back to a cheap Wi-Fi to CAT-5 device.

I have the AC68 - it's a great unit, with no issues on 2.4 or 5 GHz. The 5 GHz works great on my Thinkpad laptop running openSUSE 13.1, but its wifi adapter is 5 GHz capable. Honestly though I usually stick to 2.4 GHz so I can move about the house without the speed plummeting.

Thanks suicidaleggroll, Just unwrapped it and fired it up, and seems like a great router. Maybe a silly question, but do/can clients automatically switch between the two?

If you give both networks the EXACT same SSID and the EXACT same key, then yes your systems will be able to seamlessly switch between the two. As far as I know there's no way to control which one a device connects to though, it will probably just connect to the strongest signal, whichever that might be. For that reason I gave my 2.4G and 5G signals different SSIDs, so I know and can control which one my device is using.

On the same note, this is also a good way to expand your wifi coverage. Set up multiple Wireless Access Points around the house, all on the same network with the same DHCP server (so the rest are just functioning in Access Point mode), all with the exact same SSID and key, and your devices will jump between them as necessary. In addition my AC68, I also have an N16 on the other corner of the house broadcasting a 2.4 GHz signal with the same SSID and key as the 2.4 GHz broadcast on my AC68, so it covers the entire house.
