how to use wireless dongle

I have two Thinkpads: W10 and Ubuntu 18.04.
The W10 uses a Edimax EW-7811UTC AC wireless dongle.
I downloaded and installed the driver for this device on 18.04
but ... how do I select the hardware to use? It shows up as
connected but when I click on wireless - there is not a way to
switch to either the device or use a different frequency.
