    Has anyone experienced this problem or know a solution? I have a brand new T61 with the MC5725 Verizon EVDO A card in it. Every time I connect with VZAccess Manager, it connects and works fine for abot 15-35 minutes before it hangs and the connection locks up but the VZAM still says I'm connected. I have to turn the card off and turn it back on about 30 secs to get it to work. I've tried the drivers off Lenovo and Verizon. Neither seem to work. Occasionally I get Error 913 messages. Any ideas?

    Vista Ultimate 32 bit / VZAccess Manager 6.1.7 (1708b) / MC 5725 Driver 2.0.9.0

    Not sure if it's the same problem but this worked for me.

    I'm referring to the WWAN card not the WLAN card.

    Hey barkerwr,

    I have the same laptop as you, however I'm in Canada and I use a carrier called TELUS. I bought my laptop in July and started experiencing the same issues as you about 2 weeks ago along with 'Duplicate IP Address' errors. Today my wireless stopped working all together so I called my carrier and they said there was nothing wrong on their side. They asked me to start an application called 'watcher' which apparently comes with the sierra wireless adapter but I couldn't find it in my laptop so they couldn't troubleshoot anymore.

    I upgraded access connections to version 5 and I actually restored connectivity but I'm still experiencing the 'Duplicate IP Address' or 'IP Address Conflict'.

    I'm still looking for a solution for this ...

    Here is my ADAPTER Info:
    Description: Sierra Wireless 1xEV-DO Network Adapter
    Driver Version: MUX:2.0.16.0
    Hardware Version: MC5725 Rev 2.0
    Firmware Version: P2006000
    PRL Version: 10067
