I'd like to see what channel (e.g. 1-10, I believe) each SSID in the list is. How can I find that information?

Install inssider from MetaGeek. It is simple to use and gives you information on your and other SSIDs in your area.

inSSIDer is awesome, but I think for more users, something built into the operating system would be better. –  Joel Coehoorn Mar 2 '11 at 18:16
    
@Moab, @Joel Coehoorn What is considered good RSSI? There are a ton of SSIDs in the building I am in and I am trying to a find a spare channel. I currently get RSSI of -18 to -20. Is this good? –  AngryHacker Mar 2 '11 at 19:05
    
@AngyHacker I'm getting 4 out of 5 bars on the Win7 indicator for -60. If you look at the "time graph" window it is colour coded. -20 is well into the green! RSSI is in negative dB's so the lower the number the better the signal. –  BrianA Mar 3 '11 at 13:52
