Sound gets muted



I'm taking an online course through Zoom, and every few minutes the audio disappears for a few seconds. Shortly later I get a "Your internet connection is unstable" message on the screen.

It happens through both Ethernet cable connection and WLAN. I have a 500MB connection, tested by ping -t for 6 hours with 0% loss. My cable infrastructure provider also made a remote connection checkup and said no problem was observed.

Yesterday I took the lesson through the WLAN of a restaurant I was at, and all went smoothly, which proves that the problem is in my house connection.

Does anyone know what the origin of such a problem could be?

Hey @zikzuk, have you done a speed test, have other applications open using high amounts of bandwidth, or possibly limiting the number of devices connected pulling bandwidth from your internet?


The bandwidth used by Zoom will be optimized for the best experience based on the participants’ network. It will automatically adjust for 3G, WiFi, or Wired environments. If you go to you can check out our requirements for the best Meeting experience (which you meet). You can also check out our troubleshooting steps when using WiFI here
