I am trying to use a TechKey AC1200 USB WiFi device. I have tried it on Windows 10 and OSX 10.15 (it isn't supported on Big Sur) on my 2012 15" MBP, my 2015 15" MBP and my 2010 cMP. It fails to work on any device in the same way. Here are the key elements to this mystery:
~The device LED light is blinking normally.
~The device appears in system profiler. If I unplug it and refresh system profiler, the device is no longer listed. When I plug the device back in and refresh system profiler, the device is again listed.
~I have installed the factory drivers from the factory website.
~In "Network" under "preferences" the device is listed but the status is "cable unplugged".
~The icon in the menu bar lists the device as plugged in or not plugged in when it is actually plugged in or not. At the time of writing this, the icon switches between the Apple WiFi bar icon to a red four bar vertical signal strength icon with a red "X" through it.
~When I click on the device icon and select "join other network", no networks are detected.
~Under Windows 10, the device is detected but is listed as "not connected". When I click on it to connect to a network, the network list pops up and no networks show up.
Any ideas?
