WPA with 802.1x boot time issue, machine authentication

Discussion in 'Wireless Networking' started by Berhard Wagner, Aug 13, 2004.

  1. Hi folks, following problem:

    Config: Intel 2200BG Chipset in Acer Notebooks (WPA w. 802.1x PEAP), Netgear
    FWG114P WPA Access Point, W2K3 Server with IAS

    I am attempting to implement 802.1x on wireless using PEAP. The problem that
    I am seeing is that machine authentication is very slow to be performed by
    Windows XP clients. The machine authentication does not even start until at
    least 30 seconds after the Windows login GINA is displayed. This is
    frustrating as the machine will not be provided an IP on the network until
    machine authentication passes. If the machine is not on the network with the
    user attempts to login then the login will be local, no DC will be
    contacted, and any login script that this user has will not run, also no
    Group Policies as Computer Software Installations...

    User Authentication works perfectly, but after logon. When I log off, then
    computer authentication works also. After Standby or Hibernate it also takes
    up to 3 Minutes for the 2200BG to rescan the wireless connection and
    reauthenticate.

    Hotfix (KB826942) is installed, also the Group Policy Setting "Always wait
    for the network at computer startup", also the Wireless Settings on 2200BG
    "authenticate as computer".

    BTW, WPA-PSK works perfectly, but that's not what I want...

    Please help, thanks

    Bernhard

  2. Have you disabled broadcast ssid on the access points? I have seen slow
    connection time with 2200bg cards when it has to look for the ssid. Does
    this same issue happen with different wireless client hardware?

    Have you managed to solve the slow login problem?

    I am having the same issue where the latency in receiving a DHC
    address causes the problem of no login script and therefore no share
    drive access.

    I am using XP, Cisco PCMCIA, Cisco Aironet 1230 A/B, W2000 IAS, W200
    AD.

    Any help is greatly appreciated.
