Activation Troubleshooting

When the modem is connected to the cellular network, its WAN LED will stay on and will flash to indicate activity,
BlueVue Device Manager's Modem Diagnostic screen will display a WAN IP. If the modem is not connected, the WAN
light will be off, and the displayed WAN IP will be "N/A". This appendix covers issues with connecting to the network. If
your modem is connected to the network but you cannot browse the internet, refer to 12.3 Troubleshooting.
Each of the following conditions must be met before a modem can connect to the cellular network:
1) The modem must be within coverage, and have an acceptable RF signal strength
2) The modem must be activated for use on the cellular network (CDMA) or have a valid SIM card (EDGE and HSPA)
3) The modem must be configured to connect to the cellular network
4) If the cellular carrier requires a user name and password, the modem's connection parameters (WAN Settings)
must be configured
12.2.1 Verifying the signal strength
The modem's SIGNAL LED should always be flashing or solid ON when it has a strong enough signal to detect a cellular
network. Additionally, the signal strength is displayed in the information box in the top right of the BlueVue Device
Manager window. The minimum required for communication is 1 signal strength bar; however, a signal this weak is not
likely to provide a stable connection.
If the SIGNAL LED stays OFF, or if the signal strength is lower than -98 dBm (such as -105 dBm), there may be an issue
with the antenna or the modem may be in a low coverage area.
12.2.2 Confirming the success of activation (CDMA only)
Once a modem has been activated, BlueVue Device Manager will display its phone number in the WAN (Modem WAN
Settings) screen (some GSM carriers chooses to have the modem phone number hidden. In this case, the phone # may
appear as blank).
For CDMA modems, if the phone number is blank, or does not correspond to the account's phone number, then
activation has not been performed. Follow the instructions written in the Quick Start Guide that shipped with the
modem to perform activation. The latest Quick Start Guide is also available for download at
