    I'm looking for a program that will show me the signal to noise ratio
    of WiFi networks, specifically I am interested in checking background
    noise. Something that is similar to Netstumbler (except it doesnt
    work with my network card), something that is similar to inSSIDer
    (except it doesnt specifically show noise ratio), something similar to
    OmniPeek (except it's expensive).

    Can anyone suggest some good free WiFi tools? (Non-linux)

    Yes... that is exactly the info I need, and I know linux has several
    tools that can do it. But is there seriously not one single freeware
    program for Vista that can show the 'noise level'?

    You need a spectrum analyzer, inSSIDer tries to sell you one each time you
    launch it.
