Hi, Thanks for your prompt responses.
Another member posted some time back that the 'iw' command can set the bandwidth to be 40 MHz in addition to the default 20. So I guess user-level API support is already built in for this kind of change. Don't we just need to extend it's implementation to accept bandwidths (within the ISM band) of any width? I understand there will also be regulatory concerns, but for my research work at the moment, I was wondering how many software changes (hacks) need to be done in ath5k/9k in order to make this work?
