Unidentified Network, No Internet Access ... Again ! (On Eth Cable)

You know I checked my cables...

My "fast" cable, the one that was connected originally on the Windows machine, is a Cat5, while the other one .. the "slow" one, the one that was connected originally on the Linux Machine, is a Cat5e !!

I read on the article that you've sent me :

"If Cat 6 rated patch cables, jacks and connectors are not used with Cat 6 wiring; overall performance is degraded to that of the cable or connector."

Is that true for Cat5 cables as well? .. because that would explain why the Cat5 is connecting at 1Gbps, and the Cat5e is not.

btw...

I have connected my Windows Machine directly with the router.
Linux could not connect.

Now I am running the Startup Repair for Windows.
I asked for a System Restore.. who knows..
We'll see if it comes up with smt..

Ok I think that it is definite now...
It must be hardware...

I can't think of anything else.

I have connected the router directly to the computer.
Neither Linux nor Windows can connect.

I asked Startup Repair to do a System Restore, but nothing changed.

Can you think of anything else?!

Now... given that the network card is on my motherboard and that my motherboard is this :
ASRock > 939N68PV-GLAN

what would you suggest I do?
Buy a network card?
Do you have any links of compatible, reliable and affordable network cards?

Ok this is getting a bit AGGRAVATING !!

I found an old PCI TP-Link TF-3239DL Network Adapter.
I installed it.
Disabled the old Network connection, and the Network Adapter is working fine.

I have connected the Windows machine directly to the Router and I am using the "Linux" Ethernet cable Cat5e.

I get the same error !!! and to top it off, Ubuntu can't connect either !!!

ARRRRRGGGGGHHH !!!!!!!!!

Ideas?!!

I got a break !! But I have no idea how and why !!

I connect the Windows PC with the Switch !!

Then I just set the IP address, and although it accepts it, I don't see the address on the LAN addresses on the Router report.
I get what you see in the photos.
It does connect, but the connection is crappy! Extremely slow and full of errors as you can see in the ping results...

Hello Total

I changed it.. but I don't see different results.
I pinged 8.8.8.8 with 100% packet loss.

But out of curiosity, why I shouldn't use 192.168.1.1 as my primary DNS? When I set it to automatic this is what it does by default...

Yes I see what you mean.
Well they work ok. No problems at all..

Here's my connection information from my Linux machine, from where I am communicating..
