Router Reset Loop From One PC Only

[ChaoticChaosx]

I have on PC (that when turned on) would knock out the internet & the router would reset and keeping resetting itself trying to get it connection back,

 

2 other PCs never had an issue since the build. Also the router is from spectrum cable company if that matters.

 

Things I've done to fix this:

Factory reset router

Replaced Router (8 Times)

Replaced Ethernet Cables

Properly Re-grounded Power cables throughout the house (The Ethernet cables to the router were getting feedback and vice-versa)

Tried turning it on by itself with no other PC on.

 

The PC causing the issue Specifications:

CPU: AMD Ryzen 5 1600x

GPU: MSI Quick Silver NVIDIA GeForce GTX 1070
RAM/Memory: Corsair Vengeance 2x8GB 16GB DDR4 3000Mhz Dual Channel

Motherboard: Gigabtye Ultra Durable AX370 Gaming

PSU: EVGA Supernova 650w G3 80+ Gold

 

This has been a issue for over a year or more.

 

What could this be? Any help appreciated.

Do you have a spare NIC lying around that you can use to test instead of the built-in one? What about using a completely different ethernet/new cable?

 

Your onboard Realtek ethernet adapter seems dangerous!

No spare NIC all just built in. Yes all brand new Ethernet cables. Twice I've done this. Local area connection is my VPN and all PCs are using the Realtek.

What do you mean by dangerous?

 

Didn't reply quick earlier, cause it happened...

It can take down the entire network just by being connected to it.

 

Try another NIC.

NIC = network interface card

 

See this Intel model.

So instead of motherboard use this?

What you’ve described sounds like you have a defective onboard ethernet controller. Using a different one might solve the problem.

 

You don’t necessarily have to get the one in the link. Basically, any PCIe gigabit ethernet adapter should be acceptable provided you have the extra PCIe slot to accommodate it (usually at x1).

I do just making sure I everything right before hand. I'm to familiar with anything networking. More software and hardware. Matter of fact saying defective Ethernet controller sounds like the real answer after all this time. Thanks for all your help. I'll try this and edit this post or solved if it is the issue I'm having.
