Hardware Version: V6
Firmware Version: 1.0.4

I just installed an AC1900 (A9).  I've set up both the 2.4GHz and 5.0GHz WiFi via tplinkwifi.net.  However, my laptop will only show the 2.4GHz WiFi connections.  How do I get to the 5GHz?

Your laptop likely does not have the capability of seeing the 5GHz. To verify that, use different wireless devices such as a smart phone to see if they are able to see the 5GHz.

Hmmmm ... my phone does see the 5GHz.  It looks like my Amazon FireStick sees the 5GHz also.  Does that mean that my laptop can not take advantage of that capability (Windows 8.1)?  I didn't realize that.

 

My network adapter is a Qualcomm Atheros AR9485 802.11b/g/n WiFi adaptor.  A bit of internet searching indicates that this card will NOT support 5GHz .... sigh .... If I'd only known to check before.

What I would do is look into getting a USB network adapter that works with 2.4GHz and 5GHz. 

 

One model that should do the trick is the Archer T2U Nano.

 

You would plug that into any of the USB ports on your laptop, and you will then be able to connect to the 5GHz network on the router.
