Ethernet port on mobo works occasionally, and both ethernet ports on pcie network card just give a green light

[exowo]

Hi,

I've tried for the better part of the previous week carrying over into this week to fix my ethernet port issues.
My ethernet port on my mobo works occasionally, it used to be for a good 2 years that I had to restart my pc when I didn't get a internet connection to fix this problem. 
For example: No internet? , restart pc = internet.

This week the occasional working ethernet port problem has started occuring. Most of the time it just doesn't work, so Im using ethernet usb tethering with my android phone to get a wifi connection.

I've tried all the steps given online that I could find but nothing fixed it. When I thought that I fixed Im thinking that my ethernet port just felt like working, this was when I disabled power saving in device manager (which was somehow on in my desktop).

I've now purchased a new pcie network card which does light up orange when starting my pc, shortly after switching to a steady green which stays that way. Giving the following notification when a cable is plugged in: 

I've tried using a bootable kali linux usb stick to see if this was windows related but no luck in there either. D;

Have you restarted your modem and/or router?

 

What about testing with a completely different ethernet cable?

Tried 2 different ethernet cables and reset the router which didn't help. ;c
Disabled & enabled ethernet adapters.
Uninstalled & installed ethernet adapters.
Updated ethernet drivers.
Disabled green energy / battery saving for ethernet.
Disabled fast boot.
Disabled intel LAN in bios so it would only see the 2 new pcie card ethernet adapters.
Did a lot of commands in command prompt of which I can remember ipconfig / release & renew

which also didn't work ._.

when booting from an ubuntu live cd, does the same problem happen?

 

if yes - its a hardware issue sadly :( have you inspected the port on the mobo, and inside the actual port too? could you send some pics, close ups maybe?

 

if no - try backing up and reinstalling windows (clean install)

 

also im not sure from your post if the pcie ethernet card works or not - or does that have the same issue? if it works id just use that.

also have you tried disabling all non essential network adapters via 'network connections'? sometimes but rarely it can be as simple as that

 

does plugging the same cable into another device cause the same issue? this is important - because if it still doesn't work, then its either a cable issue or a router issue.

 

have you checked your ipv4 settings and made sure its not using a static ip address it shouldn't? is your router still working as it should for other pc's?

update:
solved the issue.
-my mobo ethernet port is a potato.
-the pcie network card I received is dead

A friend of mine had a server grade pcie network card laying around and offered it to me for 35 euro.
Solved all my issues.

I like to believe Im a pretty techy person, however I was used to having a ethernet connection which sometimes works when turned and when it doesn't, I'll just restart my pc and its fixed. Its been like this for a couple of years. ...

When my ethernet port was "functional", the highest I ever saw was 70 Mps. Now I can reach 250 Mps.

I've also disabled my mobo ethernet port in the bios settings, since its a potato anyway.
