Realtek Ethernet Controller Driver Slow Internet

I've been working on this issue for about the past 8 hours. I booted up my pc and there's a pc monitor with a cable and a red X icon where the wifi symbol should be. I've literally tried everything!
I reset my pc, took out the cable for 10 minutes, took out my ram for 10 minutes, reset my cmos, flashed my bios, and updated my driver.
I used my other working pc to download the realtek drivers and transferred the files via USB and tried to install them, and I'd get an error saying: 'The Realtek Network Controller was not found. If Deep Sleep Mode is enabled Please Plug the Cable'. I did everything in this video :::: [video='https://www.youtube.com/watch?v=EGJKKb0_Gpk&index=1&list=LL-hhtOrH-nxIaCPribRiaKg'][/video]
but that didn't work either. In the video, if you skip to 1:04 where he's viewing the device manager, you see that he has a tab that says Other devices, and then right under that it says Ethernet controller. I have the same exact thing, but it doesn't say Ethernet controller, it says unknown device. This makes no sense.
I try to connect a wifi adapter, but the pc doesn't recognize it. I connected my Ethernet cable, and still no luck. My motherboard is the Asus rampage V extreme.
I've looked on threads throughout here, but nothing works. Please, I really need help. Thanks in advanced

  1. Asus laptop with a Realtek PCIe GBE Family Controller wired network adapter using Windows 7. It takes 2 hours to copy a 3 gig file over the LAN. Why is my Realtek NIC slow? It is not the cables. I have downloaded the latest driver. Here are the control panel advanced settings, the settings are default.

Realtek ethernet controller driver slow internet service

Asus laptop with a Realtek PCIe GBE Family Controller wired network adapter using Windows 7. It takes 2 hours to copy a 3 gig file over the LAN. (Using the wireless connection is faster at 25 min). I get the same result if I boot to Ubuntu so it is not the OS. Other computers using Windows XP the copy finishes in minutes. It is not the cables. I have downloaded the latest driver.

Here are the control panel advanced settings, the settings are default.

I got access to a network with a win 2003 server and was able to copy files at high speeds with my laptop - so the problem is NOT with my network card at all.

The computer I was trying to copy to on my network is running Windows XP. Other computers on my network running Windows XP can copy OK to each other.

So the new question is: Is there some problem with Windows 7 or Ubuntu copying to Windows XP that would slow down the process drastically?

Slow

I have disconnected the router from the internet, then disabled firewall and ms security essentials on the XP machine. After that, copy speed was restored.However, after I turned firewall & mse back on & connected to internet it is still working ok. So, problem is fixed but not sure why...
