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!
Hello both of my windows XP machines are reporting "Windows in Unable to find a certificate to Log you On".
I thought that at first, perhaps, a virus and/or malware somehow got by and changed/altered the wireless settings, though the antivirus software and Malwarebytes software is up-to-date and is showing no problems. One of these may be doing strange things with the connection. If that does not work it could be a newtork card driver issue. However, before you do that I would advise you to make sure that you have the driver disc for that netcard (or for the notebook if it is an internal Wi Fi netcard), because Windows will often not have built-in drivers for any given netcard.
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.
Also, since I was able to connect from my laptop with no problem, it led me to believe it was something wrong with my desktop.
The question is, How to solve "The certificate is not valid and cannot be used to verify the identity of this website" error? Here are the details: I have a signed applet that has been working fine, until I updated Java to 8u25 (1.8.0_25-b18). I've checked the java console when this happens, and this warning message is displayed right after these lines: security: Obtain certificate collection in SSL Root CA certificate store security: Invalid certificate from HTTPS server network: Cache entry not found [url: https://sub.domain.net:9876, version: null] The application is downloaded from a different domain, say "https://app.domain.net/.....", so no jars are downloaded from "https://sub.domain.net:9876", but the applet connects to "https://sub.domain.net:9876" to send/receive data.
Now, the application shows an alert message "Do you want to continue? The applet is signed correctly, and so far, it meets all the security requirements according to Java.
I have a HP Mini 110-1000, in connecting to the router by its HP Wirless Assistant, it has a message saying, "Windows was unable to find a certificate to log you on to the network . On the other hand, the wireless network connection keep showing 'validating identity '.
Can you please tell me how I can solve this problem?
