Multiple problems with Ethernet connection

I'm on Ubuntu Live right now. Is there a way to configure NIC settings? It was trying to connect, but fails and says that network cable is unplugged, then tries again in a few seconds. I turned off auto-connect and used the wireless instead. It's similar to what I have when I try anything above 10Mbps Full Duplex in Windows.

On a side note, trying to get onto Seven Forums with Firefox on Ubuntu is at least 3 times slower. Youtube and reddit are fine though.

The problem is that I can't connect through Ethernet on Ubuntu. It keeps on telling me that it's disconnected, but it continues to attempt connecting. The only way I bypassed this problem in Windows was to set Speed & Duplex to 10Mbps Full Duplex, which apparently I can't do in Ubuntu Live.
Either way, I had the eth0's IPv4 settings screenshotted, and did the ifconfig anyway without a successful connection. I did both of these before I activated Wi-fi in Ubuntu.

I previously connected to another computer (a laptop) to test the Ethernet cable as you told me (I disabled the wireless beforehand). It worked fine, and I could browse websites with little trouble. If needed, I'll do it again and post screenshots, along with a ping test from command prompt.

Looking for an NIC in my local computer store now...

Hi, I'm back!

Bought a NIC for $15 CAD, works like a charm. Here's ipconfig from Window Command Prompt:

I'll do it again in Ubuntu if needed.
