I've been having a problem where restarting the userspace handling for my wifi would make it stop working entirely. I eventually tracked this down to the conflation of txpower.disable and rf_kill; if I make siwtxpower not change radio_enabled, it all works as expected. I think there are two issues: # iwconfig iface txpower off # echo 0 > /sys/class/net/iface/device/rf_kill # iwconfig iface <anything> Causes the radio to go back to being disabled, to the confusion of userspace (or at least, me), since it's not expected that changing other settings will kill the radio again. Also, I think I was having a problem with: # iwconfig iface txpower off # iwconfig iface txpower auto because it tries using REPLY_TX_POWER_TABLE_CMD before it unkills the radio, but the part that's supposed to respond to that command is shut off when the radio is killed. And it seems to fail, therefore, and then not actually unkill the radio. Is "txpower off" (or !radio_enabled) supposed to disable the radio completely (such that the driver can't turn on the chipset temporarily to configure it or get its configuration), or is it just supposed to be a power saving measure, and not affect the availability of other operations? -Daniel *This .sig left intentionally blank* -- 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
