Configuring Windows XP for a PPPo E connection is as simple as creating a new connection using the New Connection Wizard.Internet service providers that support industry-standard PPPo E server functionality will work with the PPPo E client supplied in Windows XP.
It says something about windows not finding a certificate.The weird part is that I was using WPA TKIP with the passphrase and it was working fine.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.To fix, you go into the properties page of your wireless connection, go to "Wireless Networks" tab and then to Properties of the chosen wireless network you are trying to connect to.
Then go to "authentification" tab and untick the box saying "Enable IEEE802.1x to the availiable network" and that should solve your problem Graham UKRight, Graham's solution worked for me.
I had been able to connect previously, but the connection would always indicate that it was validating.
However, it didnt work, until I disconnected, turned the power off my Wi Fi, unchecked the tab in the authenticate dialog box, clicked ok, then switched the Wi Fi power back on, and reconnected.
I'm currently doing a spare-parts build to put a media computer in the living room, and having a devil of a time getting my Rosewill RNX-6300 wireless card to connect to my network.
I'm trying to set it up using Windows as opposed to the proprietary Rosewill software -- the Rosewill software is a little over my head.
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.
