So, at 2.45 GHz it works reliably? And not at all for the rest? I'd
triple-check you really are setting the freq on both tx and rx (and not
just changing a variable that isn't propagated to the devices, for
example). There's no frequency-specific code in the OFDM stuff.

And of course make sure there's no interference on those other frequencies.
