How are you doing such a change?

Well, that was clearly going to happen. > Ideally we should be able to handle all the config changes right? Not sure. How does this config change work? I'd have expected the AP to stop beaconing and kick everyone out if you actually reconfigured it to no longer have VHT since then it can't do VHT rates any more either according to the new config? What exactly are you doing, and how does the AP behave, and what do you expect to happen? 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
