Ubuntu, No Wifi Adapter

I have installed Ubuntu 18.04.3 as a persistent storage, live USB version on an old Seagate external drive. I'm getting a "No Wifi Adapter Found" error in the Wifi settings once I boot into this Ubuntu Drive. My network adapter readout from 'lspci' is 00:14.3 Network controller: Intel Corporation Wireless-AC 9560 [Jefferson Peak] (rev 10) I dowloaded the corresponding linux supported drivers and copied it to /lib/firmware folder. After restarting my computer I still get the same error message. I double checked the /lib/firmware folder for the .ucode file and it was still there. Any help is greatly appreciated.
