Funny thing, I noticed that if I type in any random numbers/letters for other secured networks in the area, the same thing occurs. Well, she only has a laptop and likes to movie around.
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.
If that does not help, then consider uninstalling the Wi Fi netcard.
(Note: you may need to restart the computer.) If it is WPA encryption, make sure you are using the TKIP type and it is set correctly in both the router and the new machine’s connection.
I've just installed Windows XP SP2 on my HP Compaq 6710s. Wireless connection gets detected but does not connects. When Laptop is started it says "Windows was unable to find a certificate ........." something like that.
Now click on the Wireless Networks tab and select the network in the list at the bottom.
Click on Properties once you select the wireless network that is having problems.
Also, make sure that you are using WPA(2) Personal (PSK) for both the Comcast gateway, and for the Wi Fi client that you are setting up; don't try to use "WPA-Enterprise" or "802.1X" security because that almost certainly will require resources that you don't have (resources such as a security certificate for that connection).
I can't provide you with a screen shot of how to do this because I don't have access to the Comcast gateway that you are using, or to a setup screen for your unnamed Wi Fi client. She still has the original box that the computer came in along with a bunch of discs, including the Driver Recovery CD.
To verify that the server certificate presented to your computer is still valid, select the Validate server certificate check box, specify whether to connect only if the server resides within a particular domain, and then specify the trusted root certification authority.
To use a different user name when the user name in the smart card or certificate is not the same as the user name in the domain to which you are logging on, select the Use a different user name for the connection check box.
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.
