I can only got rid of it by going to authentication tab and un-checked the Enable IEEE 802.1x thingy.But since it will do no harm to my network or computer I will just leave them disabled for the time being. After checking various forums, advice was to unclick the 'enable IEEE 802.1 authentication box in the router properties.
Im not sure that is the Advanced tab you are talking about.
Reset or change the security settings on the two wired computers. For right now I just disabled (unchecked) "Enable IEEE 802.1x Authentication for this network" on both wired computers. But now by doing so, would it do any harm to my network? If you have a home network, it's unlikely that you have a RADIUS server - so that's OK.
Note: IEEE 802.1X security is the highest of those available. Because the key is not shared - it's issued by the server, and is unique to your machine. While both WPA2 and WPA security are excellent, their weakness is that the key is shared between all systems on the network.
So if you have access (could be physical access, including say a stolen laptop) you will be able to find the key which will allow any system access to the network... However Im still confused of why all of the sudden validating identity shows up right after I replaced the router from DI-624 to DIR-655. All I did was released the IP before I shut down DI-624 and plug the DIR-655 in powered DIR-655 up and off I go.
So I guess I will leave the IEEE 802.1x Authentication disabled then.
