Need a software utility to display wireless networks, channels, etc.?

I am looking for a utility that I can install on any one of my wireless networked computers that will scan the airwaves and show all wireless networks, their signal strength, their channels, the utility will scan all channels to find the clearest ones, it can check the throughput of each channel, etc.?

I'm having problems in my house with interference and I can't seem to figure out what channel to use or my wireless router for the least interference. I have cordless phones, 2.4ghz wireless keyboards and mice, tons of electronics, microwave, etc.

Thanks

While there are others, this one is a simple straight forward way to see what's nearby. Download NetStumbler 0.4.0 Build 554 - Detect Wireless Local Area Networks (WLANs) using 802.11b, 802.11a and 802.11g - Softpedia It won't show throughput, but will show you what else is nearby, it's channels, encryption, etc. I'm not sure what OS's it's compatible with, but it works well on windows xp. I doesn't play well with all adapters, but give it a try...you're out nothing.

no. they use the WiFi radio, which demodulates WiFi signals. To see other users of the 2.4 gHz spectrum you would need a spectrum analyzer:

inSSIDer works on XP or Vista, VistStumbler and Xirrus work on Vista:

inSSIDer: inSSIDer | MetaGeek

VistStumbler: Vistumbler.net - Home

Xirrus gadget: Xirrus: Switching Without Wires - Press Release

Thanks for the vistastumbler link, Mark.. Been looking for something like it. Netsurveyor and inSSIDer weren't doing what I wnted.
