It doesn't matter what other APs do. CAC requires for device to sit silent for specified period of time and listen for anything resembling radar signals. Only after that it can start to transmit. And while occupying DFS frequencies, it has to continue to constantly monitor for anything resembling radar signals. So your neighbours can hapily use DFS frequencies, but your AP still needs to do the initial silence thing. The same silence thing has to happen if AP decides to switch to DFS channel from a different channel. The only way to avoid it would be to add another receiver into radio chip which would be used only for frequency monitoring (CAC, snooping, scanning, etc. You name it).Considering my neighbour's Virgin Media Superhub is sat on the 10 minute CAC frequencyaccept the fact they have to wait for 10 minutes before wifi appears
Your neighbours may use slightly older devices with obsolete firmware which doesn't conform to regulations (no, regulations did not change much in last few years, regulators got stricter at enforcing it so WiFi vendors were forced to take these regulations seriously). Or your neighbour's AP did the 10min silence during small hours when nobody noticed it and now happily sits on DFS channel since it doesn't detect anything resembling radar signals.
But as I said: defaults now avoid using 10 minute CAC frequencies, making most users happier. Which is what counts most of time. If you decide to change settings and you don't like the effect, then you can either try harder (read docs, etc.) or you can reset back to defaults and enjoy the 10min-CAC-less operation.
