sierra wirelss and Dlink

yes but the dlink is wireless and so is the laptop, ive tried everything to set it up, running windows 7, its all go the windows says its connected but its not, dlink are giving up and told me to take it back to the store, second time I tried this model, I thinking there is something preventing my laptop to connect to the usb when its in the dlink router, no worries when its plugged into the laptop via the usb port , any thoughts?
 


Yes, my first post. The ROUTER would have to be able to connect to the modem. There ARE some routers that have support for USB cellular modems -- Asus is pretty good. But unless the router has the support for the modem, plugging it into the USB port on the router does nothing.
