X200 WWAN (f3507g) compatibility issue with Juniper Network

[mc2sgp]

I have just recently received my X200 with the build-in WWAN which is a Ericsson f3507g card and found that it causes my Juniper VPN software unable to load, and I have also noticed other applications like Outlook is rather slow. When I "Disabled" the WWAN card in "Device Manager"->"Network Adapters", all apps work perfectly. I am using 32-bit Vista Business.



Can someone test and see if you have the same problem as mine? I am wondering if this is a driver issue of the f3507g WWAN card.
