Wireless internet connection problems validating identity

Check Specify Authentication mode and choose User Authentication.
As opposed to deletion and reinstalling, via the device manager, I figured I'd give it a try, updating the Broadcom 802.11b/g WLAN. After typing in the Network Key that is on the ARRIS modem, lo & behold, I got an [endless] Acquiring network address. This will get your mom on the interent and you can piddle around with the wifi access at some later time. Then find the network name, click on it, then click "Properties"Go to the second tab "Authentication"Unclick the box "Enable 802.1x authentication for this network"That should fix your problem You asked "why wireless"?
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.
What's really strange, now I noticed, that this problem is occurring with any Network in range on the list. Without actually looking at the system, it is hard to tell exactly the problem but here are 2 general things to explore: Did you by chance install any of the Comcast utilities on her machine?
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.
She's always used wireless from the get-go, and in her particular situation/setup, where the cable goes to her entertainment center, it would be impractical to run an extension coax cable as well an an extension AC cord over to the modem.
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.
