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.
When I enter the router password, the following message appears: the network password needs to be 40bits or 104bits depending on your configuration.
I tried this and when attempting to connect again, a prompt box appeared asking for a network key (also called a WEP or WPA key).
All 3 of our computers can get into the router (2 wired and 1 wireless).
Even those 2 wired computers that are showing validating identity. My ATT VOIP box, Network printer and my DLINK DNS-323 NAS all work fine.
Your computers still have the old security setting and router name on it.
After checking various forums, advice was to unclick the 'enable IEEE 802.1 authentication box in the router properties.
It finds the router fine but stalls at 'validating identity'.
Do you have the same security setting, router name, and IP address on the router?
The computers have to match the new setting with the router. HOw do I reset the settings of the computers to match the new router? IEEE 802.1X is the standard which defines authentication against a RADIUS server.
