Why does my WiFi adapter show up as a USB device when I plug it in?

Is the adapter actually a USB WiFi adapter? If it's labeled as such but appears differently, it may just need some tweaks in the settings or drivers. Sometimes, USB devices can show different functionalities based on how they’re recognized by the OS. Double-check the manufacturer’s guidance or forums for any model-specific issues.

It's possible that your system isn’t recognizing it correctly. First, make sure you’ve installed the right drivers for your specific operating system. Also, check if your distro's kernel includes support for the Archer TX20U. If you're on Linux, it might help to run a kernel update or check your network settings to see if the adapter is being blocked or not configured properly. Let me know how it goes!
