며칠 켜서 상태를 보다 보니 와이파이가 끊어지고 다시 연결이 안되는 문제가 있네요..
원인을 잘 모르겠네요..
cat /var/log/syslog |grep "reason" 로그를 살펴보니 아래와 같이 나오는 데 원인을 잘 모르겠네요..
무선랜 사용을 하면서 365일 켜놓고 사용할 거라 무선 끊어져도 다시 연결만 되면 되는 데 재연결시 오류가 발생하는 것 같습니다.
어떻게 해야할까요?

로그만 봐서는 원인을 찾기가 어렵네요.

WiFi Powersave option을 'disable'로 변경해 보시길 바랍니다.

감사합니다.

절전문제 였으면 좋겠네요..

무선 네트워크가 끊기는 현상이 또 생기네요..
이번엔 오드로이드를 재부팅안하고 USB 동글 WiFi Module 0 만 뺏다 끼우니 되네요..
왜 이럴까요?

Post by **odroid** » Thu Jan 07, 2021 6:07 pm

어느정도의 기간동안 연결이 지속되다가 끊겼는지 알 수 있을까요?

차주에 테스트환경을 만들어서 재현해 보도록 하겠습니다.
Ubuntu Mate Desktop 이미지를 사용하시나요? 아니면 Minimal 이미지를 사용하시나요?

mandooawr · Post by **mandooawr** » Fri Jan 08, 2021 10:09 am

글타래에 있는 1월 4일에 절전모드 설정하고 난 후입니다.
Ubuntu Mate Desktop 이미지 사용중입니다.

Post by **odroid** » Fri Jan 08, 2021 10:58 am

구글링 검색을 좀 해보니 dhcpd 설정에 문제가 있을때 발생하는 것 같습니다.
동일한 이미지를 설치하고 시스템 업데이트 후에 WiFi Module 0를 연결하고 일주일정도 Youtube를 반복재생해 보겠습니다.

Post by **odroid** » Mon Jan 11, 2021 4:24 pm

지난주 금요일 저녁부터 테스트를 시작하였으며, 아직까지는 끊어짐 없이 무선랜으로 유튜브 재생이 되고 있습니다.
이번 주말까지 계속 테스트를 진행해보고, 결과 알려드리겠습니다.

어제 또 연결이 끊겼네요.
어제 자리에 없어 다른 사람이 확인하고 재부팅 했다는 데.. 원인이 무엇일 까요?
로그가 안남아 있어 어제 어떤 오류가 생겼는 지 알수 없네요..

저희 테스트 환경에서는 5일간 끊어짐 현상은 없었습니다.

그런데 네트웍이 끊겼더라도 자동으로 재접속이 잘된다면 큰 문제는 아닐것 같습니다.
무선 공유기나 라우터의 전원을 몇번 끄고 켜기를 반복하면 어떻게 되나요?
공유기가 꺼졌다 켜지면 WiFi 접속이 자동으로 이루어 지나요?

nmtui 로 자동 연결 설정을 해둔 상태고 같은 AP에 물려있는 RPI들은 잘 동작하고 있어서 AP문제는 아닌 것 같구요..
Odroid N2+를 두 대 테스트 운영하고 있는 데, 오늘 다른 한대도 네트워크가 끊겨서 이번엔 WiFi Module 0을 뺏다 꼽으니 자동 연결되네요..
WiFi Module 0를 뽑다 꼽을 때 보니 따뜻+a 느낌이네요.. 따로 온도잴 수 없어서 아쉽네요..

시스템 로그나 커널 메시지에 특별한 단서가 없다면 원인 파악이 어렵겠네요. 저희는 차주 초까지 계속 돌려보겠습니다.

Post by **odroid** » Tue Jan 19, 2021 4:09 pm

260시간을 좀 넘게 테스트하고 있으며, 유뷰브 재생도 정상으로 잘되고 있습니다.
커널 로그에는 칩셋 드라이버 관련 Warning 메시지가 지속적으로 보이고 있습니다만, 무선네트웍이 끊이졌던 흔적은 못찾겠습니다.
따라서 일반적인 상황에서는 끊어짐 현상은 나타나지 않고, 특정 상황에서만 나타나는 것으로 생각되네요.

네트웍이 끊겼다는 것을 검출할 수 있다면, 임시 대안으로 USB 허브칩을 리셋 해보는 것은 어떨까요?
데몬이나 크론탭으로 1분에 한번씩 검출하는 백그라운드에서 실행하는 구조로 구현이 가능할것 같습니다.

USB 무선동글을 빼고 다시 연결하면 되는 경우도 있고, 안되는 경우도 있어서 해당 설정은 무리가 있는 것 같습니다.

다음 끊길 때 로그를 전체 캡쳐해서 다시 봐야겠네요..

Post by **odroid** » Wed Jan 20, 2021 12:24 pm

네, 잘 알겠습니다.

별도로 2월 초에 새로운 RTL8821CU 칩셋을 이용한 WiFi Module 5B라는 신규 모델이 입고될 예정입니다.
무상 샘플을 준비해서 보내드릴테니 테스트 부탁드립니다.
입고되면 받으실 곳 주소 요청드리겠습니다.

네. 감사합니다.

Post by **odroid** » Fri Jan 22, 2021 5:35 pm

330시간 정도의 테스트면 충분한것 같습니다.
별 문제가 발견되지않아 테스트 종료하겠습니다.

네.. 알겠습니다..
테스트 해주셔서 감사합니다.

다시 끊김이 발생하네요..

어디를 손봐애 할지 모르겠네요...

Post by **odroid** » Fri Mar 26, 2021 3:43 pm

접속 후 얼마만에 무선랜 연결이 끊어졌나요?
reason 4의 경우 reason=4 "Disassociated due to inactivity"라고 나오네요.
현재 /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf 파일의 wifi.powersave = 2로 설정된 상태는 맞죠?

올려주신 로그로 구글 검색을 해보니, 커널 옵션으로 usbcore.autosuspend=-1를 넣었더니 해결되었다는 글을 찾았습니다.
https://www.linuxquestions.org/question ... page2.html
boot.ini 파일의 bootargs 스트링에 추가해 보시길 바랍니다.
https://github.com/mdrjr/n2_bootini/blo ... ot.ini#L54

심각한 부품 납기 문제로 신규 무선랜 입고가 계속 지연되고 있으며, 4월 말에나 공급이 가능할것 같습니다.

mandooawr · Post by **mandooawr** » Fri Mar 26, 2021 4:48 pm

접속 끈김은 짧게는 10분 길게는 40분 정도인데 연결이 아예 안되는 경우도 있네요..
지금 연결이 안되고 있어서 현장에 다녀와야 겠네요..

올려 주신 자료를 참고해서 테스트 해보겠습니다.

mandooawr · Post by **mandooawr** » Fri Mar 26, 2021 6:22 pm

네. 적용된 상태입니다.
=======================================================================
[connection]
# Values are 0 (use default), 1 (ignore/don't touch), 2 (disable) or 3 (enable).
wifi.powersave = 2
=======================================================================
첫번째 자료는 Grub 부분을 업데이트 하는 것 같은 데 Odroid는 부팅시 다른 방법을 쓰고 있지 않나요?
Grub을 찾아봤는 데 안보이네요.. 이 부분 적용 방법은 다시 찾아봐야 할 것 같네요..
새로 Grub 파일을 만들어도 되나요?
두번째 자료는 이미 적용 중입니다.

Post by **odroid** » Fri Mar 26, 2021 6:46 pm

grub 대신 boot.ini 파일만 수정하면 됩니다.
현재 boot.ini의 kernel boot parameter에 usbcore.autosuspend=-1이 포함되어 있나요?

mandooawr · Post by **mandooawr** » Fri Mar 26, 2021 6:52 pm

boot.ini 파일에 kernel boot parameter 부분이 없습니다.

Post by **odroid** » Fri Mar 26, 2021 6:59 pm

위 댓글에 설명드리대로 bootargs string에 추가하시면 됩니다.
https://github.com/mdrjr/n2_bootini/blo ... ot.ini#L54

잘 추가되었는지 확인하려면 dmesg 앞 부분을 보시면 되고요.

mandooawr · Post by **mandooawr** » Fri Mar 26, 2021 7:38 pm

boot.ini 에 추가하고 Reboot 한 후

cat /sys/module/usbcore/parameters/autosuspend 하니

기존 2에서 -1로 변경이 되네요..

감사합니다.

원격으로 접속해서 사용하다가 잠깐 다른 일을 하고 보니 그림과 같이 에러 메시지가 발생하면서 접속이 안됩니다.

Odroid로 가서 확인해 보면 로그인 창이 보입니다.
로그인 후 그림[1]과 같이 에러 메이시가 나오고 먹통입니다.

혹시나 해서 WiFi USB Dongle을 뺏다가 꼽으면 네트워크 연결이 되었다는 메시지는 나오지만 화면(그림[1])은 까만 상태 그대로 입니다.

원격으로 접속하면 접속도 안되고 해서 전원을 뺏다 꼽으면 부팅이 됩니다.

무엇을 확인해 봐야할까요?

mandooawr · Post by **mandooawr** » Fri Apr 02, 2021 9:15 am

3월 31일 테스트를 위해 WiFi Module 0 에서 WiFi Module 5A로 교체 후 아직까지 끊김 문제는 없네요..
WiFi Module 0 문제일 까요?
며칠 더 테스트 해보고 포스팅하겠습니다....

mandooawr · Post by **mandooawr** » Thu Apr 08, 2021 11:46 am

1. could not acquire name on session bus 문제는 xdrp 세팅 문제 인것 같네요..
https://www.simonemallia.net/2020/06/18 ... s-in-xrdp/ 참고해서 변경하니 하루 종일 튕김없이 잘 됩니다.
2. 어제 부터 WiFi Module 5A에서 WiFi Module 0 교체로 원상보구 후 테스트하고 있습니다. 끊김 없이 돌아가네요..

Post by **odroid** » Thu Apr 08, 2021 4:00 pm

원격 데스크탑 xrdp 설정과 무선랜 접속 안정성과 관련이 있나 보네요. 좋은 정보 공유 감사드립니다.
잘 해결되길 기대해 봅니다.

mandooawr · Post by **mandooawr** » Thu Apr 08, 2021 4:45 pm

WiFi Module 5B는 언제 입고되나요?
빨리 테스트 해보고 싶네요..

Post by **odroid** » Thu Apr 08, 2021 6:01 pm

4월 25~30일 사이로 예정되어 있습니다만, 차주 후반에야 좀 더 확실한 일정을 알 수 있습니다.

mandooawr · Post by **mandooawr** » Mon Apr 12, 2021 1:55 pm

또 같은 오류가 발생하네요..
금요일 부터 WiFi Module 0에서 WiFi Module 5A 교체로 원상보구 후 테스트하고 있습니다. 끊김 없이 돌아가네요..

mandooawr · Post by **mandooawr** » Mon Apr 12, 2021 6:26 pm

WiFi Module 0 단종 되었나요?
https://www.hardkernel.com/ko/product-c ... nectivity/ 에 안보이네요..

Post by **odroid** » Tue Apr 13, 2021 8:49 am

죄송합니다만 지속적으로 해당 칩셋을 구입할 수 없어서 단종되었습니다.
WiFi Module 5B (RTL8821CU 칩셋)만 공급할 계획이며, 금주 목요일이나 금요일에 정확한 판매 시기를 알려드릴 수 있습니다.

WiFi Module 5B도 KC 인증 문제로 국내 판매가 곤란하게 되었습니다. 정말 죄송합니다.

대신 국내에서 구입이 가능한 아래 2종의 제품을 ODROID-N2/C4 최신 이미지에서 정상 동작함을 확인하였습니다.
NEXT-501AC (RTL8811CU 칩셋 2.4Ghz/5Ghz 지원) : 다나와 기준 약 9000원
NEXT-531WBT (RTL8821CU 칩셋 2.4Ghz/5Ghz 지원, 블루투스 지원) : 다나와 기준 약 14000원

참고로 NEXT-531WBT는 저희가 준비하던 WiFi Module 5B에 들어간 칩셋과 동일합니다.
