Guitar Hero Online… Not So Great?

I’ve tried to play Guitar Hero III online. I’ve got a Nintendo Wi-Fi USB adapter and I can connect just fine, but when I go to search for a match, I get the error 86070. The first results of my internet research said that it had something to do with Nintendo’s servers being overloaded and not able to suppourt all the matches going on. Further research, though, showed that it had something to do with a problem on the user’s end. Some problems included firewall errors, firmware problems with the router, or some other kind of thing with the calibration of the network. I turned off the firewall but it didn’t help. I don’t use a router, I use the USB adapter, so I’m not exactly sure what’s going on. Whatever, I guess I can just stick to shredding away and getting better untill better information comes out or I find out a way to fix it myself. Sometime next year, after the christmas craze, I plan on getting a new router. Mabye that will solve it?
