Internet For Entire Home Goes Out When I Plug Ethernet In
Nighthawk AX4500.
Topic, when I plug the Ethernet cable into the router for my PC, my entire internet including wifi goes out. Internet went out at 3 PM yesterday, it is 5:43 PM and I have had wifi for an hour uninterrupted without Ethernet plugged in. Friend who was a ISP service tech helped me get it to this point but we have no idea why the Ethernet cable makes it all go out.

First step is to try a different Ethernet cable.
Is the PC connected only to the router with a cable? (no simultaneous connection to anything else, even over WiFi?)
Are there any Ethernet switches involved?
- No switches involved, I do use two cables and a splitter. Will try using different cables as my next step if it doesn't work tonight when I plug in again. That didn't come to the top of my mind just because if it's causing the entire internet including wifi to go out I thought it IP or router itself related.

In the days before gigabit Ethernet, it was common to use two pairs of a cable for one Ethernet connection and the other two pairs for a separate Ethernet connection. Gigabit Ethernet requires all four pairs, so this technique no longer works.
