I have this strange issue where my LAN connection speed is very slow compared to WiFi speed.
My ISP plan is 400Mbps with Spectrum (via coax).
Coax internet is going to Cable Modem and then Ethernet cable to Wireless Router via WAN port (all provided and setup by Spectrum)
At home, I have pre-wired Ethernet across the rooms connected to a 100/10Mbps Switch. That home Switch is connected via Ethernet to the Wireless Router so Internet can be provided to the other rooms.
See picture below which will illustrate the network setup.
In all Internet speed testing, I am using Speedtest.net app via iPhone or Windows 10 and all with same setting and same target server.
Internet speed test results:

Internet speed test results:
- iPhone --> WiFi --> Wireless Router --> Ethernet --> Modem --> Coax --> Internet = ~370Mbps (which is great).
- PC --> Ethernet --> Wireless Router --> Ethernet --> Modem --> Coax --> Internet = 120Mbps (which is fine but still slow compared to WiFi connected and I don't know!).
- PC --> Ethernet --> Home Switch --> Ethernet --> Wireless Router --> Ethernet --> Modem --> Coax --> Internet = 20Mbps (which is very slow and I don't know why!!!).
