Windows 7: Multiple problems with Ethernet connection

Multiple problems with Ethernet connection

I've been fiddling around with my ethernet for a while and I'm at wit's end...

Starting about a week ago, my ethernet wouldn't be connecting when the computer is booted up. A quick reset or diagnose and it would work again. Now it simply refuses to connect, switching between the "no default gateway" problem to the "connects to router but no internet" problem.

My NIC has had a problem before and it's running on non-default configurations, with all the offloads disabled and Speed & Duplex set to 10Mbps Full Duplex. If Speed & Duplex is set to anything above 10Mbps the NIC would be unable to connect, stating "Network cable unplugged", but continues to try and identify the network every few seconds.

Expanding on the "no default gateway" problem: I've reset the NIC multiple times, sometimes it would set its IP address to one that I've never seen:
169.254.60.153
The usual IP address I have should be:
192.168.1.x
Where x is usually a number between 1 to 10.
Whenever the IP address is set to that, my ethernet would connect to "Unidentified Network" rather than the one I'm supposed to connect to.
I've tried to manually set the IP address, but it doesn't work.

I've tried command prompts like
Code:
ipconfig /flushdns
netsh winsock reset catalog
netsh int ipv4 reset reset.log
I've also tried to roll back the NIC's driver and power cycle the router and modem multiple times.

Can you guys help me pinpoint my problem? Here's the ipconfig /all if you guys need it:

wireless works fine to same router?
169.254.x.y address means: it cannot get an ip address form dhcp server. Link-local address - Wikipedia, the free encyclopedia

Why did you set dns servers manually on ehernet network card?
DNS Servers . . . . . . . . . . . : 8.8.8.8
8.8.4.4

Did you try replacing networkcable? Did you try using another router port?

The DNS servers were manually set because of an earlier problem, when I had the computer just built. If I remember correctly, those servers have something to do with Google, and I just kept it because it worked. :/

Can't find another network cable in my home; I want to try everything I can do before I have to cough out some for replacement parts, plus I don't have total control over the setup in my home.

Will try a different port, though I don't remember which port was mine...

Edit: Tried to switch the router port once, and reset the NIC so that it gets a gateway (It's almost like rolling dice). Connects, but no internet. I'm going to try the third port.

what you can try:
  1. Detach network cable form the faulty machine
  2. attach it to another machine
  3. test it

Connected the cable from the wall socket to a laptop. The connection seems to be fine. Ran a speed test and a ping test to make sure.

Does that mean my NIC is faulty?

It means:
  • the laptop is connecting wirelessly(?) Are you sure you didn't connect wireless?!!!
  • Faulty NIC
  • Faulty driver
  • Faulty network settings

I made sure to disable the wireless adapter on the laptop before I connected. The taskbar icon indicated that connection was made through ethernet.

As for the device manager screenshot - is that what you want? (attachment)
