Any Open Source Spectrum Analyzers or Wi-Fi Quality Analyzers w/ 802.11n?

[grittyminder]

Does anybody know of any open source (and free) wireless spectrum analyzers, wifi quality analyzers, etc. that are enabled for 802.11n? Anything that runs on top of Windows or Linux is fine, but I would kinda prefer Windows... the reason being because my my wireless USB adapter doesn't seem to work with Linux (I/O Data Airport WN-GDN).

Alternatively, (haha, I feel like such a cheapskate) if you know of any for-money wireless spectrum analyzers that you can download for and try out for free on a trial basis I would certainly be interested...

Then there's Airmagnet, but its far far far from being cheap/free, or yellow jacket which is a hardware solution over a software solution.

Wi-Spy looks good (I had run accross it before while searching). However, they only sell the device in North America/Europe. I don't live in any of those locations. Besides, doesn't Wi-Spy cost money? Did I miss a downloadable free version somewhere?

At a glance EAKUI seems to be for only Mac OS, or did I miss something?

I've discovered Netstumbler and am playing around with that. Are there any other options out there?

Depending on what your needs are, I used Wavemon under Linux back in the day to help analyze certain wireless data. I'm not sure if it will work for what you need but thought I'd throw it out there.

wavemon is a ncurses-based monitor for wireless devices. It allows you to watch the signal and noise levels, packet statistics, device configuration, and network parameters of your wireless network hardware.

Also ...

Kismet and Wellenreiter are probably better than Netstumbler. Both were developed for Linux but I know Kismet has a Windows port at the very least.

You'll have to check and see if your adapter is supported. I use to run Kismet, as it can also find non-broadcasting signals. Netstumbler (as far as I know) only shows APs that are broadcasting their ESSID.
