Why doesn't my network card work properly in Windows 7?

I have a HP dv9000 laptop and the motherboard has a realteck network card that doesn't work properly in Windows 7 64 bit.It won't connect to the switch I recently purchased( the card flashing lights and the light on the switch are both off and it says the cable is unplugged).When I connect it directly to the internet it works but extremely slow( 60 kB/s).I tried the default driver in Windows 7 64 bit and an older version from the internet.I also installed Vista 32 bit and tried two drivers in that OS as well.I tried with other computers ( the same switch and cable) and it works.The wierd thing is that with Ubuntu the problem is non existing.What could it be?

  1. Download & install latest network driver from the HP website: http://www8.hp.com/uk/en/support.html

    If computer is not a UK model, change to the appropriate country first (bottom-left of page).
  2. they don't list any driver for lan, only for wireless.
  3. Try downloading directly from Realtek: http://www.realtek.com.tw/downloads/

  4. I already installed the driver from Realtek official website.What's interesting is that I managed to get it working for a short time(a couple of minutes) by messing around with the driver settings.I disabled wake on lan setting and WOL and I changed some of the numbers.If only I knew what all those settings mean.Is there documentation on the internet to learn more?I already tried to google but I was unsuccessful.
