When the cable was out once at a friends I set up my cssu n900 to be the internet connection. But it was easy since they had macs, I just used the usb setting in QT mobile hotspot, that shows up on the mac as ethernet and then have the mac be the wireless router. Done

It actually worked very well.

I have not tried this with windows or Linux, so I can't help you with that. But plugging it into the router could be the easiest bet since the software and setup may already be there. For example tomato has it as a check box under usb devices, you just have to turn usb on.

Good luck.
