Internet on the laptop does not work? - 1

I have a problem with my laptop… My laptop generally has a very bad connection… It doesn't matter whether I connect it via LAN or WLAN… It can't be the LAN cable because I have the same on my PS4 and it it works fine… So I guess it's the laptop. What can I do?

Reset the network settings.
if necessary, get closer to the WLAN, so that at least the signal strength is not a sideline when you restart.

Anything else happened?
automatic Windows, driver updates?
