Disklavier

I'm about 100% positive the answer to my question can be found SOMEWHERE on this 
awesome forum, but hopefully someone can either answer it again or point me to 
where I can find the answer. My DC3M4 PRC 100 is not recognizing the piano. The 
message I get is "PRC - 100 is not connected with Disklavier." When I click on 
the "Disklavier Connect" button, I get the "initializing" dialog box up. It 
searches for the wireless LAN - TEMP, but doesn't find anything. I have not been 
successful in setting up my PRC -100 to the internet, though I have gone through 
the instructions in the manual. I have not gone to the forum to read all of the 
incredible wealth of knowledge there. I have to say, as "techy" as I am in my 
own field (I'm a teacher, grades 9-10), I am overwhelmed by the collective 
knowledge found in this group. Anyway, nothing happens when I try to 
"initialize" the PRC. I used to have to "reconnect" the PRC to the Disklavier 
and all was well. However, at this point, the PRC doesn't seem to have the 
correct interface. When I go to the "Interface updater," there is nothing in the 
"Application" tab. I cannot install anything. Do I need to download something 
from the web and then somehow transfer it to the PRC through a thumb drive? If 
so, where do I find the software? I bet I can do this directly from the PRC, if 
I could only get it to connect to my wireless network! I'm afraid my tech level 
is far too low for this wonderful machine! (I wanted to use it to record some 
excellent music at an event I just had, but couldn't make it work!)

My wireless router is a LYNKSIS WRT150N, if that helps at all. I'm operating 
Windows 7 on my computer. 


Thanks for helping if you can, and for forgiving my lack of knowledge.
