WLAN on the laptop is not?

So…

Already a few months ago it is so that my laptop does not receive Wi-Fi from home, only when I'm down right then the Internet works again, as soon as I go upstairs in my room, it's not working anymore!

Already tried to use my phone as a hotspot, but that was also bad!

Can anyone help me with how I can fix the problem, looked at a lot of tutorials, but it did not help!

The best way to explain idiots, because I have almost no idea about the matter!

Thanks for reading, hope you have an answer in stock.

Ps: It's not on the internet or on the router or anything because no one in my family has the problem, just stop my laptop!

Then I think that your Läppi actually has a problem with the WLAN or the built-in antenna and needs repair.
