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.
Thanks When you install the new DIR-655 router, you didn't copy the security setting from the old router.
Your computers still have the old security setting and router name on it.
EAP type was Smart Card or other certificate and Authenticate as computer when computer information is available was checked.
But since it will do no harm to my network or computer I will just leave them disabled for the time being.
I never mess with those settings, obviously I know nothing about the networking LOL.
My laptop the Authentication tab wasnt even there for me to mess with.
That is the reason all the sudden "validating identity" show up on the computers.
Just copy the DIR-655 router name, security password..to the computers wireless adapter should fix the in to the router with the computer that can, you know 192.168.0.1, go to advanced/network filter, check that MAC filtering is disabled, the go to WIFI protected setup, check that it is disabled, usually the DIR-655 has at least one of them enabled by default Ummm, my wireless laptop never had problem with validating identity only 2 wired computers are should validating identity.
Just those 2 wired computers are displaying validating identity, otherwise all of my networking work perfectly.
