Hi. So I've been an IT tech for 3 years but I'm currently experiencing something that I've never seen before.
Here's a diagram of my setup at home: View: https://imgur.com/pddDYBg
Here's a 3min video that I recorded of the problem:

My ISP's 'dish' (NanoBeam 5AC Gen2) is on my roof and a LAN cable runs from there into the ISP's microfilter, and then a short LAN goes from there into my router. My router serves as the DHCP but it does so automatically (meaning I could factory reset my router, and I'd still have internet as the ISP's 'dish' (NanoBeam 5AC Gen2) actually does all the difficult stuff.. anyways, I then have a LAN cable running from my router into my PC, and another LAN cable running into another router in another part of my home, and THAT router has multiple mobile devices connected to it as well as a wired connection to my Xbox. All wifi connected devices on both routers have no problem at all.
So, here's the problem that literally started today (It had been running 100% fine this way for over 4months, with both routers having multiple devices connected to them and not having any problems of conflicts). My PC now gets disconnected as soon as I try to connect to my router with a LAN cable, yet the other router still works fine... BUT, if I plug the other router's LAN cable out then my PC's connection works 100% again. And then as soon as I plug the LAN cable to the other router in again, then my PC gets disconnected and the other router works again.
So it's like the other router's LAN cable is getting priority, and my PC's LAN cable immediately gets kicked when I plug the other one in. I have tried multiple LAN cables into all devices, with multiple different ports on the router, and even plugged my laptop in with my PC's LAN cable, yet the same thing happens to my laptop then... no connection on the laptop, until I unplug the LAN cable that goes to my other router. I have also changed the static IP of my PC to 192.168.0.200 and 192.168.0.210 and 192.168.0.150 just to make sure it's not conflicting with anything.
So... I've confirmed that it's NOT a faulty LAN cable, and it's NOT a fault port on my router. What could the cause of this be?
