    We have 250+ IBM T40 with the IBM PRO/Wireless LAN 2100 3B 802.11b card
    installed. Laptops run WXPSP2.
    Driver is which is the latest we can find.

    We are using Cisco 1200 Aps with PEAP-TLS authentication.

    When the machines startup they connect perfectly initially....but the ping
    times are all over the place to a wired server:

    eg: 113,19,72,28,255,23 ms
    when running a Toshiba satellite 1800 with its 802.11.b card over the same
    setup the pings are uniformly 2ms.

    then...after a *random* time (usually about 5 minutes) we lose the wireless
    connection on the IBM altogether....and authenticationm starts
    again...sometimes it works and sometimes it doesnt.

    We have a couple of T40s with the 802.11a/b/g card installed and they seem
    to be rosk steady on the WLAN, despite having a later driver. So it seems as
    though there is an issue with the
    2100 3B + XPSP2 + PEAP-TLS ????
    Anyone else expereincing similar problems?

    Anyone know of a newer driver or other fixes we can try? We *really* dont
    wan to have to buy 250+ new cards to get these T40s to connect with

    similar problems noticed

    I've noticed similar problems with WLAN in my T40, running Windows XP.
    That's happening with 3 different wlans so the problem should be in the laptop. Driver version is (Intel, 7/13/2006). This is very annoying.
