Wifi has a very short range

[JensGustav49]

Hello, my WLAN Access point seems to fine. Other Device have good connectivity at a distance 4 time the distance of the Notebook in troubles. Bluetooth seems to be with poor performance as well. My feeling is it is a HW problem. Centrino Cipecard or Antenna. The NB ist updated at a regulare. Any Experience is very Wellcome.

I ran the utility but couldn't see any change on Network related driver files. And it did not solve the problem.
The big question is, does it make sense to replace the centrino Advanced N-6235 and or the antenna?
The wlan worked earlier perfekt, but I had to disable and enable the Centrino device from time to time to make it run at all.

And yes I will buy an actual Product soon since the Notebook cannot run Windows 11 for some Reason.

I hope the number above is that which identifies the NB correcly
