      I have an HP Compaq nx7400 notebook and a wifi router (ADSL 5102G) and they just refuse to work together. I did the above change through the command prompt, but still doesn’t work! Used to run XP Pro on the same notebook and my wireless connection worked sweet… none of that now. It’s a bugger since I now have to work via a cable.
      Has anyone come across a resolute solution for something of this sorts?
      Thanks

      @Waldo. I’m headed out with the family today but I found a couple good guides you can try. If you still can’t get it working let me know.
