Question Dropouts on network when someone uses WI-FI calling over network - Asus rog rapture gt-ax11000

[Megamattzero]

My router is: asus rog rapture gt-ax11000
My ISP: Spectrum 400mb/s
My basic config: Gaming with Open NAT top of priority - Streaming Devices - VoIP last on priority chain.
Devices connected to network: 14+

So long story short my network experiencing dropouts every time someone uses wifi calling over their phone. This person's phone has no actual cellular service so he has to connect to my Wi-Fi to make calls and receive calls until he pays his bill.

My conclusion it was him because My PC is connected via ethernet and he was sitting next to me when he received a call. Suddenly my PC got no network access. I checked around the house to all other devices. All other devices couldn't connect either.

What strange phenomenon am i experiencing?

Thanks!!

In a way ethernet should have priority over wifi. Since it has more total bandwidth it has the ability to consume all the internet bandwidth easier. The wifi signal does not directly have impact on the ethernet.

Voip uses almost no bandwidth and really neither does your game. Your router likely has no concept of VoIP to it the traffic look the same as say game traffic. It does not favor 1 type of traffic over the other.

In any case there is no way a VoIP call can eat 400mbps. The only thing I can think of is the device is some how in conflict with the router IP address. That is unlikely but it is the only thing that makes sense.

Even if you wanted to you can not use the QoS settings in your router. The router uses a NAT accelerator to get 400mbps if you use features like QoS it turns that off and the cpu will bottleneck your speed under 300mbps or so.

@bill001g , remember Spectrum is VERY assymetric. My 400Mb service only has a 20Mb uplink. VOIP shouldn't tax a 20Mb flow, but the OPs "400Mb" is less relevant for this discussion.
