have you tried a wired setup from the router, some routers need to be set up this way before setting up wireless.
you need to follow the below instuctions first this should give you a basic setup:
turn off everything i.e modem router and computer
then connect the computer to the router (via a wired connection)
turn on the modem and wait for the steady light to stop flashing
then turn on the router when thats ready turn on the computer.
that should give you a basic setup via the router, then you need to go into the router settings and set up dynamic ip and the security settings.
you should then be able to connect via wireless on your laptop with your username and password you set in the security settings on the router
