I am just being pedantic but you said
"Just tried to set router exclusively to WPA2 with AES (no combinations) and had to connect withwire because all my computers refused to connect wirelessly."

Can you clarify that you DID NOT set it to WPA2 with AES but in fact you set it to
1.Security mode---> WPA/WPA2-Personal(PSK)
2.Authentication---> WPA2-PSK
3.Encryption Technique--->AES

I occasionally get confused between WPA2 and WPA2-PSK and just like to keep things clear in my mind.
