Problem connecting to home wireless network

[Siq Mawsh]

I have troubleshooted properly. My PC just connected wirelessly to my router with authentication WPA-PSK, and encryption AES. I used the exact same settings on my TP to connect and I still get the "unavailable" after I try to connect(and I'm still getting the extra 3 asterisk's for the network key when I go back into the network's settings after removing and entering in info for a new network). I even tried reserving an IP for my TP on my router with it's MAC address, and still nothing. It's a problem with the security because I connected when it was an open network. Afar from that I don't know what to do.
