    [Microsoft Lync Server 2013] White Paper: Delivering Lync 2013 Real-Time Communications over Wi-Fi

    As unified communications consultant, one of the most important things to evaluate during a project is the network, offering real-time features with delay, jitter or packet loss directly impact user experience.

    Microsoft released an interesting white paper about it's solution over Wireless environment, he is now available from the Microsoft Download Center.

    Description:

    Microsoft Lync 2013 communications software on multiple platforms and device types is now validated with voice and video (real-time media) workloads over wireless local area networks (Wi-Fi networks). The guidance and documentation provided here also applies to Lync 2010 deployments and earlier releases. However, full Wi-Fi support will be available only with a Lync 2013 client. Changes in the Lync media stack available with Lync 2013 will improve overall performance on high-loss, high-jitter wired or wireless networks. To optimize the wireless infrastructure, in particular for real-time media traffic, this guide provides details regarding Wi-Fi (WLAN) technology, configuration settings, and optimization. In addition, this guide provides deployment recommendations and evaluates typical enterprise, public hotspot, and home Wi-Fi deployments for real-time bidirectional media quality.

    [Cisco] Windows 8 clients can't associate to Cisco Unified Wireless

    Actuellement, si votre contrôleur Cisco WLC est dans une version inférieur à 7.0.235.3, les utilisateurs ayant un os windows 8

    c'est un probleme faisant l'objet d'un kb microsoft: http://support.microsoft.com/kb/2749073 :

    Les clients Windows 8 n'est peut-être pas en mesure de se connecter à des infrastructures sans fil existantes à l'aide de certains routeurs Cisco, contrairement aux ordinateurs Windows 7 et XP.

    Cause

    Windows 8 peut rencontrer un problème lorsque vous essayez de vous connecter au réseau sans fil de Cisco Unified. Si le client est à l'aide de gestion des clés WPA ou WPA2 avec chiffrement AES, la connexion peut échouer. Avec « débogage client » en vigueur sur le contrôleur de réseau local sans fil, un message semblable au suivant apparaît :

     *dot1xMsgTask: Jun 12 20:23:37.471: 00:11:22:33:44:55 Retransmit failure for
    EAPOL-Key M1 to mobile 00:11:22:33:44:55, retransmit count 5, mscb deauth count 0

    La résolution est simple, il suffit de mettre à jour le firmware du contrôleur WLC: https://supportforums.cisco.com/docs/DOC-27213

    Windows 8 clients can't associate to Cisco Unified Wireless

    The problem - Windows 8 clients can't associate to CUWN

    Windows 8 wireless clients can encounter a problem when trying to associate to the Cisco Unified Wireless Network.  If the client is using WPA or WPA2 key management with AES encryption, then the pairwise key exchange may fail.  With "debug client" in effect on the Wireless LAN Controller, a message similar to the following is seen:

    *dot1xMsgTask: Jun 12 20:23:37.471: 00:11:22:33:44:55 Retransmit failure for
    EAPOL-Key M1 to mobile 00:11:22:33:44:55, retransmit count 5, mscb deauth count 0
     
    This is the Cisco bug CSCua29504.  This problem is also documented as Microsoft Support Article ID 2749073.

    The solution: upgrade WLC software

    This bug is fixed in the following releases of WLC software, which are available to download from Cisco.com now:

    7.3.101.0
    7.2.111.3
    7.0.235.3
