    Hi there,

    using like +30 WinXP old tablets; they connect via Wireless (WLC) and then authenticate against a IAS Radius.

    Everything works fine but sometimes a random tablet stops working and it fails the auth process all the time. The only way to solve this issue is to connect this tablet via ethernet, let it authenticate, and the connect again to the wireless network.

    Client NIC

    Modelo: Intel (R) Wireless WiFi Link 4965AG
    Versión controlador: 11.5.0.32

    Any idea of what could be happening?

    Thanks a lot!

    Hi Mitheor,

    Thanks for posting here.

    So it seems the wireless authentication will success when using EAP-MSCHAP v2 as the authentication method , so could you general describe the entries (authentication method ..etc)we specified in the wireless profile on these tables and also the policies we defined in IAS?

    Meanwhile, did we also get any error/warring message relate with this authentication issue form client which might include reason code or event ID.

    Hi again and thanks for the answer,

    screenshots of client side config:

    Tablets does not use certificates, the authenticate instead using EAP-MSCHAP v2.

    If you need for me to translate any of those lines just let me know.

    In the tablet there is no error, just trying to connect endlessly.

    I´m checking the windows traces but i´m not seeying nothing useful  :$   Probably my fault because i´m not used to browse this files.

    Hi Mitheor,

    Thanks for update.

    So please first collect these information from both wireless client and IAS/RADIUS server with following the introductions in the article I posted and upload here(SkyDrive maybe and we can post the URL here ). Once we get these data, it should be more easier for us to narrow it down:

    Troubleshooting IEEE 802.11 Wireless Access with Microsoft Windows
    http://technet.microsoft.com/en-us/library/bb457017.aspx

    We had also some potential known issues when we do 802.1x authentication on Windows XP clients which has been fixed by corresponding hotfixes, the detail information could be acquired from the blog post below:

    Possible problems seen after upgrading Windows XP clients to SP3 in an environment that uses wired 802.1x

    Otherwise I think we might get misconfiguration caused that and hope the collected data will help.
