I am trying to dual-home my RPi 5. I purchased a dual-band wifi 5 usb adapter that turned out to be an: Realtek RTL88x2Bu. I can't seem to connect and stay connected to my 2nd network. I have tried two different network and same result. I am just using the desktop wifi icon to select the card and then the SSID.
The logical name/interface name of the Realtek usb wifi card is: wlx90de80ca358a. Note, the correct drive is listed in the lshw command: driver=rtw_8822bu. Note, also that system-connections have been created for both the 'ez share' and 'gr.1.11803' networks...but, no IP address is attached. Both these networks use DHCP. What's happening/not happening? Will I be able to get this USB nic to work?
