Intermittent ethernet disconnects

[xnoobftw]

Hi recently my PC has been experiencing intermittent disconnects.

It usually happens in the middle of the night and for about 2-3 seconds before coming back on.

 

What I've done

1) Bought a new ethernet PCIe card and used it (seems to decrease occurrence by ~70%)

2) Reinstalled drivers for both PCIe ethernet card (realtek) and onboard motherboard ethernet drivers

3) Cleaned ethernet cable on both ends with the router's port and my PC's ethenet port with alcohol wipes

4) WIFI was still working when my PC disconnected during that 2-3seconds.

 

I know the cable could the obvious problem but i really wanna exhaust all other options before replacing the cable (it's well trunked and a pain to replace).

Any suggestions?

Possible cable is the issue. Possible bad wifi router/switch. Ports can go bad.

This means it is not from you,

This standard hours should be from the ISP...

issue is my wifi works perfectly when my PC disconnects. Most likely a cable issue? But it's not like it's regularly disconnect (there isnt a pattern). 

I've also swapped the ports my cable connects to on the router

Issue could be cable or the swithc in the back of the router. The ports can go bad and wifi still work fine.

I though it was regularly disconnect ....

it usually does it in the middle of the night but throughout the day it's fine and wifi's working fine during disconnect as well. (it could happen in the middle of the day but that's like once every 3 days).

Try a cable first

I would plug another computer in and see if it happens to both computers.

If not, you should reinstall windows.

If it does, replace the router.

would it be safe to assume that the cable is okay? Because these steps would assume so

Unless you moved something at the time it disconnected, the cable is most likely not the problem.

Thank you!! I'll give it a shot
