my laptop disconnetcs from wifi after about 20 minuites. then i have to restart my laptop and it would connect again. does any

Solution
It may not be the laptop that is the problem. It could be the ISP.

Some devices, when a connection is dropped (internet goes out, even for a moment) they will reconnect right away. Others do not. Sounds like this may be what is going on for you. I would try running a program or two to keep an eye on your internet connection. See if there are any issues. If it shows any, then contact your ISP and have them fix the issue.
