VM3 WWAN Connection Manager
Access the VM3 Connection Manager from the icon in the system tray. Double tap the
Connection Manager icon (or right-click the icon and select Configuration Panel). The
Connection Manager icon looks like this:
Use the VM3 Connection Manager to:
• Configure WWAN connections
• Configure hyper-roaming between WWAN carriers or between WWAN and WLAN..
• The Connection Manager roams from WLAN to WWAN when the WLAN signal is weak
enough to allow the roaming. Due to the fact that WWAN signals are present in most
areas, it is unlikely the Connection Manager will roam back to a WLAN connection
automatically. User intervention may be required to switch back to WLAN.
• Roaming to or between WWAN carriers is different than roaming between WLAN
access points. In order for WWAN to roam, the Connection Manager must first
disconnect from the old WWAN carrier then establish a connection to the new WWAN
carrier.
• When hyper-roaming (either between WWAN carriers or between WLAN/WWAN) the
network connection is temporarily lost during the switching process. When switching
to or between WWAN carriers, the connection manager must load carrier firmware
and this can take several minutes.
• If there is a connection issue, the first step in troubleshooting is to verify the APN on
the
Connection Type tab.
