I can't get my Mac Pro, iPad or Toshiba Win7 laptop to connect

I can’t get my Mac Pro, iPad or Toshiba Win7 laptop to connect to anything but the guest account. I’m not a networking guy so any help would be appreciated. I set up the 2.4 & 5 gig networks to WPA2 Personal with the same password for now. They see the networks but won’t connect. With the ipad I get a message that says the passwords don’t match. With the Mac Pro laptop I get a message saying that the router needs a WPA password. I’m lost.

Hi, try using another password and security protocol.

yeah the firmware seems still buggy. Have you tried upgrading to the latest firmware, making a backup of your router settings in the admin area, reset to factory settings and finally reloading your saved config file?
