A7000 WiFi USB Adapter Firmware Upgrade and Genie

I'm trying to use the Genie to check and possibly upgrade the firmware on my AC1900/A7000 WiFi USB Adapter. I have the latest version of the genie, and when I hit "check for update" it gets to 20% every time and just stops. I've let it set for an hour, and it never moves. It always stalls at 20%, have uninstalled and reinstalled several times, and issue keeps happening. I believe I have firmware in need of upgrade, but don't know how else to do it. Tech support didn't seem to understand the issue or wasn't too interested in it, so I have no alternative. Has anyone else experienced this, and how did you fix it?
