RE: My wireless card activity could notberecognizedbyNetworkManager

Dan,

My HAL version is 0.5.7-3.

What Can I do to make HAL know my wireless interface? Do you know some
HAL Q&A or related doc?

Appreciate your help!

This is really an issue between the driver and HAL.  If you get it to
show up in HAL, then it will show up in NetworkManager (and then we can
see if your driver does WEXT right :).  In any case, what version of HAL
do you have?  Then we can track down exactly how HAL is looking for
wireless.
