Jim,
It's not completely clear what configuration the tech left you with, but perhaps it is because the configuration sounds so bizarre. From what you're saying it sounds like your wireless router is connected by Ethernet cable to your PC (which is very normal). And it also sounds like the tech tried to use a wireless connection of some sort using a USB connected to your PC that apparently would communicate with the piano and then (through the PC) with the wireless router.
First, I think you realize that what you need for an Internet connection to the piano is something connected to the Ethernet port on the piano. While your DC2M4 has an 802.11/b wireless network of its own from the factory, it is used to wirelessly connect the small PRC-100 with the piano. In the simplest scenario, you could simply disconnect all of the crap the tech had you buy (assuming your wireless router is still working), and run a long Ethernet cable between the Ethernet port on your piano and one of the Ethernet ports on your wireless router. That would work fine and allow you to connect to the Internet through your wireless router, except that it would not be "wireless" because of the Ethernet cable between the piano and the wireless router. To eliminate that Ethernet cable, you can buy a "game adapter" which has an Ethernet input and which has a wireless 802.11 "output" that will connect up with your wireless router. I used a
Linksys WRT54G game adapter, which cost me about $90. In looking for a link for you, it seems that that product may have been eliminated. If you need some help, let me know and I'll try to find an alternate. In any event, you need a wireless transmitter on your piano (in addition to the 802.11 wireless transmitter that is used to connect your PRC-100 to the piano) to connect with the Internet. You will end up with two wireless networks emanating from your piano, which I think is pretty cool.
By the way, all is not lost with the wireless USB adapter the clueless tech had you buy. You can use it (if needed) to have your PC wirelessly connect with your wireless router, rather than having an Ethernet cable running between your wireless router and your PC (which is the configuration I believe your are describing).
When I first had my DC3M4, I had lots of issues, so I think I know how it's done. My own issues stemmed from using a Linksys "wireless bridge" that the dealer loaned to me since he couldn't get it to work and which I eventually concluded simply did not work (I think it was effed from the get-go). The tipoff to me should have been that it came with a device driver CD that was included with the "bridge", which I obviously couldn't install on my Disklavier. After talking with Yamaha customer service, they overnighted to me a working game adapter which worked instantly (and a copy of which I immediatly purchased). In any event, get yourself some kind of a game adapter, and let me know if you need some more help.

Can anyone assist in setting up a wireless network. I purchased a new DC2M4 and the technician who installed did not really know how. He had me purchase a wireless G USB adaptor to communicate with my router and set up the USB on my primary PC where the router connect to. I don't see how that makes sense and it certainly doesn't work to plug the USB adaptor into the disklavier. I'm afraid I have the wrong hardware. Thanks!
