Sadly I have a high speed connection now, however the EV-DO usb modem I got isn't supported by regular wireless routers so Id need to shell out 400 bucks for an EV-DO router to share the connection to my Nintendo and thats just not happening anytime...ever.
sigh...
I have no idea if the usb dongle thing would work.
I already tried a LAN-USB cable and it doesn't work because you need a router for it, even though I can share the connection over ethernet to another computer. I was assuming I could connect my nintendo directly into my computer via the LAN cable adapter but that doesn't work, so Im skeptical that the USB dongle would either.
