WPA 신청자가 호텔 WiFi에서 NIC를 끊거나 연결을 끊습니다.

긴 이야기 짧게

USB Wi-Fi 동글을 사용할 때 Raspberry Pi 3에서 WPA 신청자가 간헐적으로 실패합니다. 호텔의 액세스 포인트를 "재연결"하거나 변경할 때 이렇게 하는 것 같습니다.

WPA GUI 상태: "wpa_gui가 wpa_supplicant에서 상태를 가져오지 못했습니다." 및 무선 연결 아이콘이 연결된 "wave"에서 "무선 인터페이스를 찾을 수 없음" 상태의 두 모니터로 변경됩니다.

무선 카드 연결이 끊어지는 것을 어떻게 막나요?

내가 시도한 구성/사항:

  • USB WiFi 동글을 전원이 공급되는 외부 USB 허브(USB 3.0, 4Amp 전원 공급 장치)에 별도로 연결하세요.
  • /etc/network/interfaces"무선 전원 끄기"라는 용어를 사용하여 wlan1(동글) 파일의 "전원 관리"를 "끄기"로 전환하고 네트워크 서비스를 다시 시작합니다.
  • /etc/default/crda변수 "REGDOMAIN"을 공백 값에서 "US"로 변경하도록 파일을 수정합니다 .
  • 액세스 포인트를 가리키는 이득 값이 10dbi인 방향성 평면 패널 안테나를 사용하십시오.

Pi 및 동글에 대한 정보:

  • Raspbian Jessie 커널 버전 4.1 실행(2016년 3월 18일 출시)
  • uname -a"Linux raspberrypi 4.1.19-v7+"를 의미합니다. #858 SMP Tue Mar 15 15:56:00
  • lsusbRT5730 무선 칩셋을 나타냅니다. 이 카드는 Raspbian에서 기본적으로 지원되어야 합니다.
  • 동글은 현재 2dbi 이득 무지향성 안테나와 함께 제공됩니다.

이 문제에 대한 추가 정보:

  • 무선 카드는 여러 액세스 포인트와 다른 많은 사용자가 있는 호텔 WiFi 네트워크에 연결됩니다.
  • 내 주변에는 최소 18개의 서로 다른 액세스 포인트가 있고 가장 강한 방송은 약 -47db입니다. 신호 강도는 문제가 아닌 것 같지만 간섭이 발생할 수 있습니다.
  • 이 문제는 장치가 동일한 네트워크(동일한 ESS의 다른 AP)에 있는 다른 액세스 포인트로 재인증하거나 (아마도) 변경될 때 발생하는 것으로 보입니다.
  • 문제가 발생한 후에도 ifconfig에는 여전히 wlan1(문제 카드)이 표시되지만 IP 주소가 할당되지 않았습니다.
  • 문제가 발생한 후에도 iwconfig는 여전히 wlan1을 표시하고 액세스 포인트에 연결되지 않았다고 말합니다.
  • 이 문제는 USB Wi-Fi 동글을 파이 또는 USB 허브에 다시 연결하면 일시적으로 해결될 수 있습니다.
  • 파이는 개인적인 사용을 위한 액세스 포인트로 내부 카드를 실행하고 있습니다.
  • wlan1(동글)의 트래픽은 NAT를 통과한 후 wlan0(AP)에 브리지됩니다.
  • Raspberry Pi의 AP 네트워크 카드는 802.11g 모드에서 약 -27dbi로 브로드캐스트합니다(2.4GHz로 가정).
  • pi는 Epiphany 브라우저를 통해 호텔 네트워크의 종속 포털 인증을 처리합니다.
  • 허브와 USB WiFi 동글은 파이에서 약 1피트 떨어져 있습니다.
  • 연결은 30초 동안 유지될 때도 있고, 4시간 동안 유지될 때도 있습니다. 큰 차이.

연결이 끊어졌을 때 시스템 로그(죄송합니다. 내용이 좀 깁니다. Markdown에는 숨기기/숨기기 해제 기능이 없습니다.)

해결책

wlan1 카드를 설치 network-manager하고 network-manager-gnome연결했습니다 /etc/network/interfaces. 카드는 20시간 이상 안정적으로 연결되었지만 라즈베리 파이를 끄면 연결이 끊어졌습니다. WPA Gui는 "wpa_supplicant에서 상태를 가져올 수 없습니다"라고 말하지만 카드는 여전히 작동합니다.

nm-applet권한 문제가 있는 것 같습니다 . 그런 다음 무선 네트워크에 sudo pkill nm-applet연결 해야 합니다 . 이러한 오류를 수정해야 합니다.sudo nm-appletnetwork-manager-gnome

답변1

/etc/modprobe.d/rt2800usb.conf다음 줄을 사용하여 새 파일을 만듭니다.

options rt2800usb nohwcrypt=1

재시작

또는 기본 드라이버를 블랙리스트에 추가하고 해당 nl80211드라이버를 사용하여 다음을 통해 연결합니다 wpa_supplicant.

nano /etc/modprobe.d/blacklist.conf

다음 줄을 추가합니다.

blacklist rt2800usb
blacklist rt2x00lib
blacklist rt2x00usb

명령줄을 통해 연결:

wpa_supplicant -Dnl80211 -iwlan0 -c/etc/wpa_supplicant.conf

GUI가 필요한 경우 WICD를 설치하고 인터페이스를 선택한 다음 환경 설정으로 이동하여nl80211
