불안정한 Wi-Fi 카드로 인해 전체 컴퓨터가 충돌합니다.

저는 오래된 MacBook에서 Debian 9를 실행하고 있습니다. Linux에서는 Wi-Fi 카드의 연결이 비교적 자주 끊어지기 때문에 Wi-Fi 카드에 하드웨어 문제가 있는 것으로 의심됩니다. macOS에서는 연결 속도가 매우 느리고 속도도 느립니다.

그럼에도 불구하고 대부분의 경우 잘 작동합니다. 나는 가끔씩 연결이 끊어지는 것을 개의치 않습니다. 한 가지 이유 때문이 아닙니다. 때때로 (데비안에서는) 연결이 끊어지면 전체 컴퓨터가 멈춥니다. 포인터를 움직일 수 없고 키보드가 작동하지 않으며 화면에서 아무것도 움직이지 않습니다.

항상 이런 일이 발생합니다. 먼저 웹 페이지를 열 수 없다는 것을 알았습니다. 몇 초 후 네트워크 관리자는 WiFi에 연결되어 있지 않다고 보고했습니다. 몇 초 후에 전체 정지가 발생합니다.

내 설치에 대한 세부 정보:

• 모든 최신 업데이트가 포함된 Debian 9
• 커널 4.9.0-6-amd64
• WiFi 드라이버용 Firmware-b43-installer 패키지
• 무선 네트워크 카드:Broadcom Limited BCM4322 802.11a/b/g/n Wireless LAN Controller (rev 01)

불안정한 WiFi 카드로 인해 전체 컴퓨터가 충돌하는 것을 방지하는 방법은 무엇입니까?

컴퓨터를 다시 시작할 때 마지막 줄이 첫 번째 항목이라고 생각합니다.
