[Solved] Can't Change Security Settings on WNDR3700

Hello, 

I am trying to add a password to my WiFi security on my WNDR3700, but for some reason, I cannot. When I login to my router and attempt to change it, the setting won't even move. It's just stuck on "none" and won't move to any other type of security. I've tried resetting and unplugging and all the usual stuff but nothing seems to work. Any help would be greatly appreciated. Thanks!
