Is my Ethernet port broken?

myminimuffin · Jul 25, 2017

Hey,

How do i determine if my ethernet port is broken?

I cant connect to my router through ethernet cable on my PC.

The router works
Cable works (tested on diff computer)

When i connect the cable to my PC it keeps saying that i have to connect a cable even if its connected. I also cannot seem to find my ethernet network, all i see is a TAP- Windows Adapter v9

Well it seems like you are missing LAN drivers, if you can't find your adapter.

Gingerbread :

When i try to install the Killer Network Driver, it says

"You need to have the right Killer Hardware to install Killer Performance Suite"

What is your motherboard and has the LAN worked at some point?

Yes, worked earlier today, had an accident with the router as it just stopped working, got a brand new one now of the exact same type. So before i aquired a new router i tried to uninstall the Killer Network, but now i cannot install it again

Why did you uninstall it, also did you perhaps disable the device in the Device manager? Also did you try downloading the latest driver from MSI's website and for your appropriate windows version?

Gingerbread :

Uninstalled it due it messing up before.
Did not disable it in device manager
Yes, tried to install the newest one, but then i get the message that i need the appropriate Killer Network hardware if i want to install it, even tho i do have that.

What version of Windows do you have and how many bits?

myminimuffin · Jul 25, 2017

Corwin65 :

Windows 10 64bit

Can you post a screenshot of your device manager Network Adapters tab?

If you put a cable in the LAN slot does it still blink (orange light or any light)?

myminimuffin · Jul 25, 2017

Gingerbread :

No lights whatsoever when i plug it in, also no lights around the slot on my router where it is connected (as it should be)

Hm, check your BIOS and see if the LAN is enabled (my guess is that it would be). If it is enabled, then turn off the PC, unplug it from the PSU (or turn the psu off) and remove the CMOS battery for a few seconds.

Gingerbread :

Did what you said, nothing changed

Gingerbread · Jul 25, 2017

Then it sounds like your LAN is dead, which is really strange judging on how suddenly everything happened.

myminimuffin · Jul 25, 2017

Gingerbread :

I guess it might have something to do with my router dying at the same time as i mentioned?

Oh well, thanks anyways

Gingerbread · Jul 25, 2017

Yeah chances are it burned the onboard LAN. Maybe you should try detecting if there is any electricity at all left in the port.

Another thing that can be checked is if the cable itself is fine. Do you have another cable to test with; or another set of hardware to test the cable? I know it can be rare, but it is possible if the RJ45 connector separated from the wire at all.

go to device manager and click on your Ethernet port driver file, disable it then re enable it. also update driver through the device manager. if this still does not work then most likely you have burnt out your Ethernet card.
