Skype Zoom Video conferencing issues drop outs and freezes part 3

Apologies mods, I've been brandished by another wannabe mod in another thread, so I apparently need to start a new thread, despite this being the same issue as 2 other threads. 

During Skype/Zoom calls with multiple participants, the internet connection intermittely drops out.


As per the other thread, for me, the root of the issue appears to be intermittent high packet loss to the upstream gateway when using any VOIP application with multiple participants - it's easily reproducible. When this happens, it doesn't just affect the Zoom/Skype call, but all internet connectivity.

Here's an example from my router logs this afternoon, whilst on a Zoom call with 10 participants:

Mar 16 13:15:17 dpinger WAN_DHCP Alarm latency 38950us stddev 84800us loss 21%
Mar 16 13:16:28 dpinger WAN_DHCP Clear latency 136162us stddev 185503us loss 10%
Mar 16 13:23:45 dpinger WAN_DHCP Alarm latency 71767us stddev 138229us loss 21%
Mar 16 13:24:54 dpinger WAN_DHCP Clear latency 58380us stddev 111333us loss 10%
Mar 16 13:31:20 dpinger WAN_DHCP Alarm latency 38495us stddev 98512us loss 21%
Mar 16 13:32:20 dpinger WAN_DHCP Clear latency 15658us stddev 33100us loss 10%
Mar 16 13:57:17 dpinger WAN_DHCP Alarm latency 30815us stddev 68079us loss 22%
Mar 16 13:58:55 dpinger WAN_DHCP Clear latency 37071us stddev 96287us loss 8%
Mar 16 14:03:54 dpinger WAN_DHCP Alarm latency 38662us stddev 82056us loss 22%
Mar 16 14:05:28 dpinger WAN_DHCP Clear latency 11147us stddev 17463us loss 6%
Mar 16 14:17:01 dpinger WAN_DHCP Alarm latency 55191us stddev 93754us loss 22%
Mar 16 14:18:14 dpinger WAN_DHCP Clear latency 51586us stddev 123762us loss 7%

Note: "Alarm" is when the router detects an issue with the upstream gateway, "Clear" is when the issue has resolved itself. Internet connectivity in general corresponds with these times. is the Gateway that my SH, in modem mode, has given to my router.

During these outages, pinging the router works fine. Pinging another device on the network is fine. Pinging an external IP doesn't work.

When not using VOIP applications, internet connectivity is fine. It feels like there is some form of QoS in place for VOIP calls, at the network level, which is causing issues.
