I'll let you know what happens. In the ath5k case as well, I'm willing to bet it has something to do with dual band operation. IIRC at least some instances of this in the past were due to getting the rate after the band was changed, e.g. due to scanning, and the peer of course didn't support any rates on that band. -- Bob Copeland %% www.bobcopeland.com -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
