In Linux there's iwconfig, iwlist, etc.
In Windows, is there anyway to get more advanced view of the properties/statistics of the wifi signals I see? Something other than the couple of bars and the standard IP settings? Ideally I'd like some information to help troubleshoot connectivity problems-- IE what channel my neighbor's wifi is on, what the SNR of my wifi is, etc.
If no such thing exists is there software available that would give me that information?
