Hi SNB Gurus!
I have a strange (at least for me) problem with Zoom video calls and my home Asus router(s). I have 2 routers AX88U and GT-AX11000 Pro, both running the newest Merlin firmware. I'm not using them simultaneously, but I have tested this behaviour on both routers. My ISP nominal speeds are 700/50, in reality, I'm getting over 800 download and 45 upload speeds.
I have two Macbook Pros, one is M1 Pro 2021, the other is M2 Max 2023. They sit next to each other and don't have any anti-virus or anti-malware software that could block the network. Both are connected to the same home 5GHz wifi, with signal strength ~-40dBm.
When I join the same Zoom call from both laptops, the M1 machine sends video in very poor quality (320x180, 3-4fps), but the M2 machine sends HD quality with 30fps. When switch the M1 to my mobile phone wifi (5G) the quality improves and when the M1 laptop is used at my work, the sent video quality is HD.
Now, this is a bizarre observation: I can fix the M1 video by 1) installing and enabling the Cake QoS on the router AND 2) adding the predefined Zoom iptables rule with UDP port rang 8801:8810 in the Cake QoS settings tab. Just enabling Cake QoS without the iptables rule doesn't help at all.
What is this rule in the iptables doing in reality and would it be possible to enable it without the QoS? I don't think I need QoS with my Internet speeds.
Thanks!
Tom
