Can't see other peoples video in meeting - extreme packet loss on Receive Video statistics

[MLH]

Hello

I have been using Zoom successfully for the last 18 months at home.

2 days ago I started having the problem where all other people are a black screen.  I can see myself but can't see others (when their video is turned on).

This is the same problem across different devices (mac, android, PC)

Same problem with different meetings in different parts of the country

This is the same problem is wired or wireless.

Same problem if I log in using different accounts.

The statistics page shows severe packet loss on the Video -> Receive side (like 80% to 99%). See screenshot

All my other programs such as Netflix function fine

Speed tests are fine.

Of note however is: the problem goes away when I don't go through my router at home. I tested tethering to my mobile phone hotspot and the problem is resolved (albeit a very slow connection given the nature of my mobile reception).

I have updated the firmware in my router and tested with my ISP to check if there is problem with my actual internet connection. All ok from what they can see.

Would value anyone's feedback and potential workarounds.

Regards

Hello @RN thank you for the follow up. I managed to fix it yesterday by updating the firmware on my modem which was about 3 years old. It does not however explain why the error occurred seemingly spontaneously as I have been using the same modem for the last 3 years and zoom was working well until last week.
