Hello.

My internet was working flawlessly after formatting my PC and installing a clean Win7.
After I ran some Windows Updates on the machine, I'm having network issues.
I managed to figure out, that it may have something to do with the duplex, which I know basically nothing about how works.

When using "Auto Negotiation", I get "no connection" error.

I searched and searched the web and came around an article saying to change the "Speed & Duplex" to "100 Mbps Full Duplex"...
This worked... Or so I thought.
For some reason it only allows about 1-2 Mbps download and 13 Mbps upload (tested with speedtest.net). Keep in mind that my connection is 90/90 Mbps and running above 100 Mbps up and down on my main PC.
Funny thing is... When I change the "100 Mbps Full Duplex" to "100 Mbps Half Duplex" I suddently run about 13 Mbps download... Still not what it should run.

We have 5 PCs in our home. 3 connected through cable, of which one has the issues.
The other 2 are laptops are connected wirelessly.

I have tried the following:
Deleted the driver/card and restarted the PC to install the drivers again.
I've changed the Duplex (kind of worked...).
Tested the cable on my main PC - It worked!

I know the PC is quite old, but it's not that old, that Auto Negotiation shouldn't work (as of what I can read, old PCs doesn't work properly with that?).

I should add, that I have forced an IP to the PC (as I need access to it from outside my home. Currently running MySQL and PLEX).
But even with auto IP it's not working.

Can anyone assist in this matter?

Thank you, very much in advance!

sounds like a cable issue. full duplex allows transmission and reception at the same time. half duplex means it only send or receives data, disables the ability to do both at the same time. by running half duplex sounds like your eliminating some cable interference.

because I believe that videos can help you more check for this the following shows how to run a ping test to check for packet loss. if you get a lot of timeouts it most likely a cable issue as your wireless is fine.

As I mentioned in my OP, I have tested the cable in my main PC and there's no issues.
I've also tested with 2 other cables on the PC which has the issues... Nothing worked.

It is not a cable issue. It occured after an update to the system.
I'll try and install Win10 and see if that fixes the issue.

EDIT:
I noticed that when I go into Network & Sharing center and open the connection it says: Speed - 4.2 Gpbs (on the Auto negotiation setting).
I guess this is where the error is, as it should say 1 Gbps at most (I think the network card only allows for 100 Mbps though).

A bunch of Windows updates. I don't know which nor how many updates there was applied.
