PC internet problems?

I sometimes have to go to a team meeting in Discord because my friend runs an MCPE server with over 100 people, but it has been happening for a long time now that after 5 minutes or so my PC disconnects from the Wi-Fi for 2 seconds and then connects again. I've endured it for a long time now but it's getting really annoying. I've also been banned from a couple of servers because I'm just trading in the middle of trading or simply disconnecting mini-games, but I can't help it. I have an Acer laptop (Windows 10). But I know that the problem is not the WLAN, but the PC because my other devices don't have such a problem and my parents' other laptops don't have this problem either.

If you see the cause with the PC, which probably has a WLAN problem, then set up a LAN connection WITH THE PC!

E.g. Herewith:

Do you get z. B. Also at Media / Saturn stores, but certainly also alternative products.

My parents already bought a repeater, it worked for 3 months, it still works, but my pc doesn't work
