Cisco VPN Client Problems

    We are using the Sony Ericcsson wireless cards and Cisco VPN Client
    version 4.x to a Cisco 1721 router running IOS 12.2. The problem that
    is occuring is users with the wireless lose VPN connection frequently
    after connecting.

    I understand with wireless cards there is some amount of packet loss.
    However we upgraded the VPN to Cisco from PPTP recently and before the
    change we never had issues with clients losing VPN connection.

    This doesn't occur when using the VPN over a broadband(DSL) or dialup
    connection, so it would appear there is something going on the
    wireless end that is "breaking" the VPN connection.

    Does anyone else use the same configuration (Cisco VPN over wireless)
    and have these issues? Are there any settings to try?

    You use an AP which is in turn connected to the Router ?

    What about the SA liefetimes ? Maybe set too low
    because of the higher throughput.

    No we use a GPRS Internet service on the cards from AT&T Wireless. So
    the connections come through the Internet.
