Big Sur and Monterey require different kexts for your WiFi. There is a different kext for all the most recent macOS releases, going back to High Sierra for Airportitlwm.kext.
You will need to change your Nvidia graphics card for an AMD card if you upgrade from High Sierra, as HS was the last version of macOS to support the Nvidia Web drivers. Your GTX 1080 Ti will not work with full acceleration in Mojave or newer versions of macOS.
So you may want to think about changing your graphics card before you upgrade macOS.
