Re: DFS and radar
If DD-WRT is not doing the correct thing here, feel free to open a bug with them about it although would be curious is if the hardware is capeable of DFS but if it's not, it's probably better to disallow the channels completely. I imagine the problem is also in the other direction. If you are using these bands around a radar system, I'm guessing the frequency will be close to unusable for data transfers.
