I have a new laptop (MSI GE66 raider) and recently installed ubuntu (dual boot with windows 10).

I noticed that my wifi download speed was slower on ubuntu than on windows 10. I tried reinstalling the adapter and so I followed the instructions on this answer: No WiFi Adapter Found with fresh Ubuntu 20.04 install on MSI GE66 Laptop, and other strange behavior

When I rebooted, my wifi settings disappeared and now I have no access to wifi.
