Disklavier

How is your Disklavier connected to the network? Is it through a 
remote Airport Express or hard wired to the Extreme base? If so, is 
the Airport Express "n" compatible, and, if not, did you set up the 
Extreme base station to be "802.11n, b and g compatible?" If using a 
previous Airport Express, did you reconfigure it to extend your new 
network?
