The wireless modem may be the trouble in your laptop. Plug a USB cable directly from the router and see if your laptop recognizes the network. If it does, the problem is, most likely, your modem or modem software. If you narrow it down to the modem, google driver updates for your modem and see if that solves it. If new drivers doesn't fix it, you'll probably need to replace your wireless modem or get an external wireless modem.
