This led me to NixOS/nixpkgs#271020 (comment).

And adding hardware.enableRedistributableFirmware = true; to my configuration.nix file fixed the issue 🎉

Thanks again!

Do you see anything related to wifi when looking at one of these?

journalctl -b | grep wlp3s0
journalctl -u NetworkManager
journalctl -u wpa_supplicant

dmesg | grep wlp3s0
dmesg | grep wifi

lsmod (look for WiFi modules loaded)

Also, did you take a look at this and ensure it's represented in your config?
