Network Connection in Progress. Please try again later. - Dell AIO 966 pinter with wireless adapter

My wireless connection was reset.  SInce then, my printer will not connect.  When I go to the Network setup menu, I get the message in the subject above - "Network Connection in Progress.  Please try again later."  It never goes away.

I cannot figure out how to reset the wireless setting on the printer so that I can join it to the network again.  I have powered it off, uninstalled and reinstalled the wirelesss card.....still nothing.

Any ideas on how I can reest this thing?
