I really could do with a device to scan the WiFi RF spectrum in an area as I suspect it has major interference.
There are devices commercially available that produce graphs - examples below:
Problem is those graphs were generated by Wi-Spy and accompanying Chanalyzer Pro software which costs $999.
I'm only going to use it once and am fairly broke so that just isn't an option.
Does anyone know of ways to do this on the cheap?
