When using Merlin X950D 3G on the Rogers network in Ontario Canada with Windows 7 64-bit the computer freezes. It worked with no problems in Vista 64-bit. It does not always freeze right away but eventually it does freeze. When using the laptop without the 3G adapter connected to WiFi instead the computer runs fine and does not freeze after hours of use.
When installing Windows 7 I did a clean full install and not the upgrade option.
