[SOLVED] When I plug my pc to the router everything connected with ethernet cables stops working only wifi stays one ???

[kristof55pl]

Hello
As the title says all of a sudden recently my internet stopped working after some troubleshooting I found that when my pc is connected to the router the internet stops working for all devices connected by ethernet including my pc
when I unplug it Internet comes back the only thing that works when my pc is connected is the WIFI
I ve bought a new ethernet cable same thing happens and I've got a new router still the issue persists can someone please help me I dont know what to do I am starting to think that this issue comes from my pc
I spoke with my ISP and they are just useless no one know's I have an engineer scheduled for saturday but I feel like this is something that can be fixed

malware scan the system?

 

[kristof55pl]

On it I ve done a quick scan that didnt do anything but I am doing a full offline scan right will update you in a short while wether that fixed the problem

 

[kristof55pl]

nope its still not working
I ve also done a system restore to a date that I know everything was fine still broken :L

 

[rgd1101]

what the pc hardware spec? could be failing and causing issue

 

[kristof55pl]

What part motherboard ???
Windows 10
Evga 1080ti
I7 7700k

2 ssd's
Mobo asus prime z270-p

On your PC ensure that only the wired (Ethernet) network adapter is enabled when using wired connectivity. WIFI network adapter should be disabled.

Next, check the IP addresses: especially the router (lkely to be something like 192.168.1.1) and the IP address of your PC.

Make and model router?

Run "ipconfig /all" (without quotes) via the Command Pprompt.

Also run"arp -a" via the Command Prompt.

Post the results of both runs.

Could be an IP address conflict.

Boot up a linux live cd/usb and see if the same thing happens under that live os. If so, potential hardware issue or a configuration in the router.

Could be an IP address conflict.

This was my initial thought as well. But it also could be some sort of hardware issue, hence I think a live cd test would validate both scenarios.

Or even cloned MAC address collision !!!

Thank you all for these fast replies but I spent more time troubleshooting and turns out my on board ethernet port is faulty
I moved my computer downstairs to try the other ethernet cable that works and the same thing is happening
I decided to buy an PCIE network card my should work fine on that right ?

 

[rgd1101]

if it is the port on the motherboard, yes a pcie network card should fix that.

It's not necessarily bad. It would just be windows.

Boot up a linux live cd/usb and test it there. I'm almost willing to bet that it will work fine there. And if it does--windows issue.

If it does the same thing, then yes, hardware issue, and a simple pcie nic should fix the issue. You can even get a usb 3.0 external one if you want.
