Tell us about the computers and the router.

What computers do you and your son have, laptops with wireless options, PC with cable connecting to the router? Is the router a wireless capable router?

With wireless laptops what we normally say is, connect the laptop to the wireless router by cable first to set up the connection with the router. Then access the router's Setup page in a browser using the router's manual to follow instructions, then setup the wireless access from there.
