    I'm having problems with Cisco's beta VPN client ( and bringing my
    laptop back from sleep or hibernate. It enters sleep fine, but after
    resuming my connection (in this case, wireless) is permanently dead. In
    addition, IE no longer starts, the control panel opens but is empty and I
    can't get to any meaningful network settings.
    If I disable the adapter before sleeping, things behave a little better
    until I reenable it. Then the same as above happens. In addition, disabling
    and renenabling after sleeping eventually results in a BSOD with
    This only occurs with Cisco VPN client installed. I don't actually have
    to be VPN'ed into anything, just having it installed (and therefore adding
    the VPN device) is sufficient. If I uninstall it, sleep/hibernate work as
    expected and my wireless card behaves properly on a resume (even switching to
    a new network if I've changed locations). Has anyone else seen this? Any
    known work arounds? -- Dan

    Thank you so much for posting this. I was having this problem and it was
    driving me crazy! Any time Vista came back from sleep or hibernate, the
    wireless connection would be totally unrecoverable, IE7 would no longer
    start, the control panel would open but be empty and network settings were
    mostly unavailable. I found that the LAN connection would still work if
    connected with a Cat V cable.

    In addition, shut down would also freeze intermittently requiring the
    awkward Windows did not shut down properly restart - Starting normally always

    I didn't even guess that the Cisco VPN client ( was the problem.
    I was thinking it was the wireless driver - though I have the most current
    driver. I am so lucky that I found your post. Uninstalling the Cisco VPN
    client did fix the problem. Reinstalling it confirms the problem.

    I found the following solution: I removed Cisco VPN client and
    installed Cisco VPN client So far, no problems.

    If anyone needs help finding the VPN client I am using, reply to this post.

    Here are a few key words that may help others who search the newsgroups to
    find this solution: Cisco VPN client, Vista freeze, shut down, sleep,
    hibernate, wireless fails, control panel freezes, NIC
