This sounds more like a host issue to me.  I actually saw this the other
day when I tried to connect to a "new" board.  My host system insisted
on trying to look up some addresses associated with the connection and
I had to wait for the DNS timeouts (about the 20+ seconds you are 
talking about).

I'd say to make sure that the board (network) name is well known to your
host and see if it helps.
