I don't know what "the default" is. If you do ifconfig wi0 txkey - or ifconfig wi0 txkey undef then it resets the tx key state to be undefined; as it is when a device first comes up. In this state there is no default tx key to apply to outbound frames. Note that this is a change in behaviour from before my changes to support WPA. I found that having the default tx key set by default is error prone. Unfortunately I missed adding this to UPDATING and have yet to update the various manual pages because some of this code is still a bit fluid. I will add it to my TODO list. > > One thing I find odd is that the wepkey isn't automatically set as the Tx > key as well.

Having implicit side effects for operations like setting a key can be a pain. ifconfig has the netbsd nwkey shorthand that you may find useful. > > Either way, I've added this to my list of things to look at.
