@erik_squires if your power is low so that your neighbors will not see your SSID, then they are not clogging up your radio channels.
Whether the neighbors are causing channel congestion for me has nothing to do with my own router, or even lack of a router. That’s on them and their transmit power and the channel that their router is sitting on. In an ideal situation routers would spread their signals across all available channels, or at least say "oh, look, there's six other SIDs on channel 4, let me use 8 instead." but even today that doesn't happen very well.
Turning my router off, or setting it to 10% or 100% doesn’t change my congestion problem.
