Indoor Cam wont connect

Just picked up a 1080p plug in indoor cam to try to catch some garage theives. What a disappointment, I've been trying to get it to connect to wifi all afternoon and it fails every time. Too far from the router? Nope, even with them sitting right next to each other it doesnt work. It keeps telling me to check my password. I know I am entering it correctly. Troubleshooting is as useless as this camera. I'm ready to return it I'm so pissed off. Hopefully someone can help me figure this out.
