MSNdis_StatusMediaDisconnect "event" occuring. why? what is this?

[George S. Lockwood]

Please see inline...

Did you happen to see my other email re: switch connections and the three
use cases?

I did follow your advice and remove the disconnect calls (I thought
disconnect would end the  connection to a network so you could then connect
to another).  And I was able to  the reconnect to the same network (same id
& password).  I have not tried reconnect (with different id & password)
though...I'll do that in the office tomorrow.

I haven't been able to connect to on ap, then connect to another yet....but
please read the uses cases and s'il vous plait, advise me of the correct
command sequence.

inline below...

thanks so much,

george

Don't know why it would...a very stable AP and network.

Certainly, ap_scan=2 as this is a hidden when I saw it this morning.

Of coures.  Am really asking: are there timeout controls (use of those
period variables perhaps) that could be tuned to look ~frequently at the
state of the connection and cause a reaction: reconnect attempt immediately?

I can try...the log gets very large...perhaps I can cut and paste the
console text a number of times and combine in a useful and helpful manner
for you.  Of course I could send you the config file.

But that will be in 8hrs as it is night here and I'm not in the office.

would love to see your use case recommendationed command sequences.  Perhaps
I could write up your answer with my use cases in such a way as you could
use in the user documentation.  Be glad to help you.
