I am new to Ubuntu. I finally decided to dual boot (I need windows for ONE program: ArcGIS). Everything was going fine until I took my laptop to class and realized my battery power was draining like crazy (1.5 hours remaining at the start of a 3 hour lecture).
Due to this predicament, I decided to try out tlp. I followed a guide online on how to install tlp through the terminal and my Wifi stopped working.
How can I fix it?
