Thanks - I will try the parameters you are using for the ar5416 and see if that reduces the number of false detect pulses. > I also have a tool in tools/tools/ath/athradar/ which lets you view > and set the radar parameters. You should tinker with that whilst doing > some traffic. OK I will experiment with different values and see if that helps too. Thanks Brett =20
