Can you SSH to your computer, and show me the contents of /etc/netplan/? Look for your wlan0 config file, looks like the installer script potentially changed that file. Unfortunately I do not have a system with both wired and wireless so can't test this.
SSH to your machine, and run this command:
sudo cat /etc/netplan/*
