Dlink router broadcasting "no internet acces"

[ARMANI NEIL]

hey Shane I just set up my new DIR-601 router and stopped receiving internet that i received prior to the security configuration. everything seems to be fine on the router as the lights come on the they normally did. I pick up the wi-fi signal from it with excellent status but can't as it say no internet access on my pc.
I disconnected it and set it up again yet no change. what can do i do in the meantime?

thanks

Does the internet work when you use a network cable instead of wireless?
