I’m facing a very weird bug that prevents me from using internet from my box.
When I connect to the network, first I have internet but after ~7 seconds, I’m loosing the connection and I cannot ping 8.8.8.8 anymore (the next ping line just never shows up)
Also, sometime I can connect to my box for hours until it stop working.
If I disconnect and the reconnect to the same wifi, then I have internet for ~7 seconds and then it disappear again.
If I connect to my phone wifi, everything is fine and I can use internet without limits.
If I connect my phone to the box wifi, everything is also fine.
If I had some video/audio streaming from Google Meet running when internet stop working then the streaming is not closed.
I installed the linux61 kernel but I still have the same problem.
I noticed something really weird, I was in a video call and the internet stopped working (no more ping, cannot open any web page) but the video/audio flux were still streaming and I could finish my meeting.
I really have no idea what can cause this but it feels like a firewal rule active only on new connection.
Hi @Aschen
The output of the Network Manager says you are connected at the time you run the command, I wonder whether you could post the output of the same command when you lose the connection.
Please consider to also put the output of another terminal command:
The wifi connection is never lost, it’s only the underlaying access to internet that is lost.
Here is a video so you can have a better understanding: webm[DOT]red/view/Zm0q.webm
Aschen is my wifi, I’m connected to it when the video starts
Then I connect to Fibertel, the wifi of the box
The ping goes and then stops
I deco/reco
The ping goes and then stops
The command journalctl -p 3 -xb | grep NetworkManager does not give any output.
@jmagder I made a video as well with sudo dmesg -H -w webm[DOT]red/Jwap
The output is here:
As I said, I have the same problem with a cable connection (RJ45) and one I lost internet during a meeting and the audio/video streams did not stop.
Unfortunately I don’t know the network stack enough to diagnose the problem so if anyone can helps me with some commands that I could run before and after I loose the internet connection it would be great.
Some news here, I was able (I think) to identify what cause the issue.
When I start the Docker service, few time after I’m experiencing the problems listed above but when I use my computer without starting Docker then I never loose my internet connection.
It’s really hard for me to work without Docker but even harder to work without internet. Is there any way I could troubleshoot what is happening here and eventually fix it?
Without joking, it was one of my Docker network that was messing with my routing table I think because I deleted all the Docker network and everything is fine. (docker network prune)
