Have ubuntu 19.10 on a system with an onboard 100mbps wireless adapter. Recently upgraded my broadband service to gigabit fiber. I bought a usb wifi adapter to take advantage of higher speeds. I have not been able to install the new wifi adapter. I've tried several times using instructions I found related to the realtek driver on the new device without success. I can get around in terminal and follow instructions, but I'm otherwise a linux neophyte and must be missing some fundamental knowledge. I'm stumped and need help.
