What is validating identity on wireless network
One way to restore networking, especially wireless, is to go into control panel, system and delete the network card. Since you mentioned that this notebook had previously been setup for multiple wireless profiles, my suggestion would be to delete all existing wireless profiles and see if that allows you to then create a new profile for the Comcast gateway.
I can't provide a screen shot to illustrate how to do that because I don't know if you are using the built-in Windows Wireless Zero Config, or a vendor specific utility for your unnamed Wi Fi card.
I am using a enhanced-G USB wireless adapter to connect to a desktop computer.
Whenever I try to do that it shows me some message which says "Validating Identity".
Here’s how to connect to your wireless router if you are getting this message.At the top of the screen, where it says, Choose a wireless network, I get an [endless] Validating identity.As of recently, she was able to use this computer to connect to a neighbor's/friend's secured wireless netowork and another neighbor's/friend's unsecured wireless network.If the box was checked, then that was why you were getting the “unable to find a certificate to log you on to the network” message because Windows is looking for one, but your wireless router is not setup for certificate security. Once I unchecked that box and tried to reconnect to the wireless network, everything worked fine! Hi all, I just signed up (for my elderly mom) with Comcast for their hi-speed Internet service (performance level).
