다음 구성으로 AP를 설정하려고 합니다.
- Wi-Fi 어댑터: TP-Link AX3000(Intel AX200 기반)
- 운영 체제: Ubuntu Server 20.10(그루비)
- 커널 버전: 5.8.0-44-일반
- 펌웨어: iwlwifi-cc-a0-55.ucode
- AP 서비스:hostapd v2.9(최신 소스 코드의 사용자 정의도 시도)
캐나다와 프랑스에는 거의 동일한 두 가지 설정이 있습니다. 캐나다 하나는 작동하고 다른 하나는 작동하지 않습니다. 소프트웨어 구성 차이를 배제하려고 노력하면서 결국 문제가 규제 영역과 관련이 있다는 의심을 갖게 되었습니다. 다음은 실패한 설정에 대한 세부정보입니다.
이 설정은 프랑스에 있으므로 규제 도메인을 별도로 설정했습니다.
$ sudo iw reg set FR
그것을 확인하면 (초기) 다음을 얻습니다.
$ sudo iw reg set

위의 다음 줄은 나에게 우려를 불러일으킵니다.
wlp3s0: interface state UNINITIALIZED->COUNTRY_UPDATE
Previous country code FR, new country code FR
nl80211: No channel number found for frequency 5905 MHz

올바른 국가 값을 설정하면 규제 정보가 세계 도메인으로 재설정되는 이유는 무엇입니까? nl80211드라이버, hostapd서비스, 하드웨어 등 으로 인해 발생 합니까 ? 이 주제에 대해 나에게 명확성을 제공할 수 있는 아이디어가 있으면 감사하겠습니다.

목록을 확인했는데 Intel® Wi-Fi 6 AX200 160MHz에 다음이 표시되었습니다.
2.4GHz의 AP 모드(iwlmvm 구동 장치)
답변2
놀랍게도 해결책은 패키지를 설치하는 것이었습니다 network-manager. NetworkManager에서 관리할 무선 인터페이스를 설정하지 않고도 추가 구성이 필요하지 않습니다. 다른 시스템(Ubuntu Server 20.04가 설치된 Raspberry Pi CM4 보드)에서도 동일한 동작을 복제했습니다.
Ubuntu Server는 systemd-networkd네트워크 관리를 위한 기본 서비스이고 Ubuntu Desktop은 NetworkManager입니다.
