[Solved] Linux Mint 20 Wifi Disconnects

[GamerTechUniverse]

When I use my Linux Mint system, a few minutes later, it disconnects from the internet and can't connect. I tried typing the command

Code: Select all

sudo service network-manager

, but that doesn't work for me. If you want to see my system specifications, here it is:

So far, the wifi hasn't disconnected, I will let everyone know if that changes. So thank you, for now.

Well I was very wrong, it disconnected, and I couldn't connect back to the wifi, so I had to restart the computer, let me know if there is any commands that will fix this.
