Not sure what you're asking ... restart_hw() should reconfigure everything just like you said, but maybe your driver is not cleaning up properly before the restart so something in there fails? restart_hw() expects to only do start/add_interface etc, not remove_interface/stop etc. 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
