내 운영 체제는 Archlinux이고 온보드 Wi-Fi 칩 MediaTek MT7921은 Wi-Fi-6 칩입니다. ~에 따르면이 위키MT7921은 Linux에서 80MHz 핫스팟 생성을 지원합니다.

그렇다면 NetworkManager 구성에 40MHz/80MHz 대역폭을 적용하는 방법은 무엇입니까? 구성 옵션을 찾을 수 없습니다.공식 문서.
그런데, NetworkManager가 이 작업을 수행할 수 없는 경우 Linux에 지정된 대역폭으로 핫스팟을 생성할 수 있는 다른 간단한 도구가 있습니까?

답변1
예상대로 진행되고 있는 것 같습니다. 채널 165는 다음과 같이 20MHz 채널입니다. https://en.wikipedia.org/wiki/List_of_WLAN_channels#5_GHz_(802.11a/h/n/ac/ax). 찾고 있는 채널은 Wikipedia의 40MHz 및 80MHz 열 아래에 나열되어 있습니다.
귀하의 도움말에는 iw 출력이 포함되어 있으므로 정보가 있습니다. 주파수 아래에서 Band2를 확인하세요. [대괄호 안] 채널은 모두 20MHz 채널입니다. 실제로 옵션이 거의 없습니다. :-(
즉, 하드웨어는 20MHz 이상을 지원하지 않습니다.
