Suddenly having extremely slow wifi on Ubuntu 18.04

Hi guys I recently set up kubuntu on a relatively modern pc and for the first day the internet (WIFI) speeds were fine. The next day however, I am getting speeds of under 1 mbps, whereas usually I get around 100 mbps. I checked from a different machine and verified that I was actually getting around 100 mbps and it was only an issue with this computer. Here is some additional info
