Disklavier

Ok I must say I am not too techie.  But I have your setup on my Disklavier 850 on a C3 (I think) acoustic piano.  MAC is using Snow Leopard.  First of all, I DON'T think I used an EXTEND Network concept at all. I have ONLY one Network:  (2Wire)   I used a JOIN EXISTING NETWORK concept.  Hardware-wise I have an ATT 2Wire  MODEM / ROUTER which serves as the wireless network.
Then I have a Mac computer wirelessly connected to this Network.  I bought the Airport Express and set it up through the Mac Computer to JOIN the network.  (Apple is very helpful here)  Then, put Velcro on the Airport Express, hid it under the piano and connected the Ethernet cable from the DK 850 to the Airport Express.  Then the DK 850 found the Network and Voila I can run the piano with the iPhone app and have the DK Radio feature and my Mac sees the DK 850's files.  I also connect iPhone to it with iReal b app  via RCA plug to iPhone.  Very cool play along app.

Here is what the Express reads:
Under Summary:  
Status: Normal   Mode: Join a wireless    Network Name: 2WIRE 034   Network Wireless Security: WEP 40 bit   Channel: 1   Connect Using: Wireless Network 
IP Address    192.168.1.68    

Under Wireless:    The box Allow Ethernet Clients     --> is checked.

I don't see any of that DHCP stuff at all.  And I think it is because I am using only ONE Network.
