i have an issue with my WIFI

it works fine after reboot for 8-10 minutes but then it starts to reconnect, loses connection and so on

this issue started after kernel update on my old Ubuntu 22.04.5 LTS and i found my WIFI working stable only on kernel 5.15.0-76-generic so i used it

when i upgraded to Ubuntu 24.04.1 LTS i hoped it will fix my issue, but even the last kernel 6.8.0-48-generic update did not help

i tried to copy driver folder from kernel 5.15.0-76-generic to the new kernel (ChatGPT helped), then i tried surfacego-wifi - no result

now i have two options

  1. work on ethernet cable
  2. switch to old OS/kernel

but i like new Ubuntu 24 so please help me to fix this issue

here are some details

my system parameters:

  • ASUS N551JW
  • Intel® Core™ i7-4720HQ CPU @ 2.60GHz × 8
  • NVIDIA GeForce GTX 960M/PCIe/SSE2
  • RAM 16Gb
