Using Profiler on the WLanPi

I added a garage and family room onto my house so I need to increase the wireless coverage in a few spots. I also have idiot neighbors who like to use non standard channels in 2.4, and even one neighbor who uses a 40 mhz wide channel in 2.4. Thanks neighbor. Anyway in the 5 ghz spectrum Uni I, Uni II and Uni III are quite crowded as well. I don't live close to any airports so I'm going to use DFS channels where I can. The easiest way I've found to see if your clients can use DFS is to whip out the WLanPi and use profiler.
