Download Known issue when using Novatel Wireless V620, V640 USB720

Known issue when using Novatel Wireless V620, V640 USB720 under NDIS
(Network Driver Interface Specification) mode with the Microsoft Windows
VistaTM operating system
On the new Windows VistaTM OS, there is an issue with the connection stability when using the
NDIS mode on the Novatel Wireless V620, V640 and the USB720. In order to maintain the 3G
connection, the NetBios and IPv6 services for the connection must be turned off for the network
connection. These settings are not needed for using these device and turning them off for them
has no adverse effect.
The V620, V640 and USB720 cards run by default in PPP (Point-to-Point Protocol) mode using
the DUN (Dial-Up-Networking) interface. The user can optionally choose to use the device in
NDIS mode instead. For more information on NDIS mode, please go to
