I have an internet connection that provides me with wired speeds of Download: 45 Mbps, Upload:60 Mbps.
But when I use a ADSL Wi-Fi Router, I get speed of Download: 20 Mbps, and Upload: 45 Mbps at the same location. Ping of 34 ms.
And yet I am not able to video call properly on Google Meet and Webex. My video is never visible to the person of the other side. With zoom, I face this problems sometimes but most of the times my video is visible.
This has never been a problem with 3G and 4G internet connections that offer me an even lesser bandwidth and yet my video is always crystal clear to the person on the other side.
