데비안 Jessie에서 Wi-Fi가 작동하지 않습니다

Acer E5 575G 노트북의 WiFi 드라이버에 문제가 있습니다.
드라이버를 수동으로 설치하려고 시도했으며 git에서 드라이버를 수동으로 설치하려고 apt install firmware-realtek시도했지만 apt install firmware-atheros
성공하지 못했습니다.

명확히 말하면 이더넷 어댑터는 작동하지만 WiFi는 작동하지 않습니다. 또 다른 점은 내 WiFi가 항상 Fedora와 Ubuntu에서 기본적으로 작동한다는 것입니다.

데비안에서 어떻게 고칠 수 있는지 아시나요?

감사해요.
