For the laptop all I did was typed in the SSID name and entered the WPA2 password in Broadcom utility and off I go.
For those 2 desktops after I replaced the DI-624 to DIR-655 and that is when all of this Validating Identity started.
Everything came pre-loaded on the laptop so Im not sure why the Authentication tab wasnt there.
Or perhaps it was a wireless laptop and there is no need for that tab.
As you can tell I dont know much about networking : PDuring time that I had DI-624 router.
