VBox Version: 7.2.16
host OS: Windows 10
VM OS: Arch Linux, KDE plasma (for those interested)

my host is currently connected via ethernet. i figured i could just disable the host’s ethernet network switch and then utilize a USB adapter but it seems my hubris has gotten the better of me and i just do not understand networking that well. either that, or this is a question for the arch forums. but im posting here first, since whenever i look up how to do this, all i can find is how to do the inverse; “disconnect vm while keeping host connected” which is basically self explanatory.
since my VM is linux, i popped open a terminal and used “lsusb” command, and it is seeing the Realtek wifi adapter. the option to connect to wifi is there, i do so, and it just immediately disconnects.

in my mind, there’s no way this isn’t possible at all, but it’s seemingly more convoluted than i’d have otherwise thought.
