D-Link DCS-930L :: How To Do Wireless Setup

I had to get a new router from verizon cause the old one died. so i reset the camera and wipe all the dlink software and settings. I then start fresh. i get all the way to choosing wireless and input the password. It states that there is a problem saving your settings. I tells me nothing more. I spent 4 hours on the phone with tech support and i can get it working through wired but I can't put it in my childs room wired. it worked perfectly before the router switch. funny thing is that its the same brand and model router.
