Well, if the number of different channels is 1, why would you expect to be able to start an AP on a different channel than the STA is currently using? Hostapd should know (needs to, I think) what channel is actually being used, so you should start it on the right channel I think? I don't know why association requests would fail. johannes -- 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
