tenho um problema com meu WIFI
funciona bem após reiniciar por 8 a 10 minutos, mas depois começa a reconectar, perde a conexão e assim por diante
esse problema começou após a atualização do kernel no meu antigo Ubuntu 22.04.5 LTS e descobri que meu WIFI funcionava de forma estável apenas no kernel 5.15.0-76-generic, então o usei
quando atualizei para o Ubuntu 24.04.1 LTS, esperava que isso resolvesse meu problema, mas mesmo a última atualização do kernel 6.8.0-48-generic não ajudou
Eu tentei copiar a pasta do driver do kernel 5.15.0-76-generic para o novo kernel (ChatGPT ajudou), então tentei surfacego-wifi - sem resultado
agora tenho duas opções
- trabalhar com cabo ethernet
- mudar para o sistema operacional/kernel antigo
mas eu gosto do novo Ubuntu 24, então por favor me ajude a consertar esse problema
aqui estão alguns detalhes
meus parâmetros de sistema:
- ASUS N551JW
- CPU Intel® Core™ i7-4720HQ @ 2,60 GHz × 8
- NVIDIA GeForce GTX 960M/PCIe/SSE2
- RAM 16Gb
