Cannot Connect to the Internet
1. Check the Signal Strength on the home page. If the signal strength is poor, check your
antenna connections and placement. Try a different antenna if possible.
2. On the “Dial Settings” page, confirm that the autodial is enabled. If it is disabled, enable it
and cycle power.
3. On the “WAN Cellular” page, check that the correct mobile identification number is
displayed. If an incorrect number or no number is displayed, it is an indication that your
carrier contract is not activated, or the device has not been initiated. If you have not
performed an over the air activation (OTASP for Verizon, IOTA for Sprint) perform that now.
4. If you have confirmed all of the above, or the over the air activation fails, contact your
network provider to confirm that your contract is active.
Internet Connection is Slow or Intermittent
Note:
The speed and strength of your Internet connection can be affected by many
things out of the control of the Vanguard 3G radio modem such as your location
and the overall level of network traffic. CalAmp Corp cannot guarantee any
speed or coverage.
1. Check the signal strength on the home page. If it is listed as good or medium, skip to the
next step. You may want to refresh the home page a few times to make sure the signal
strength is consistent. If the signal strength is poor, check you antenna connections or try a
new antenna if possible. If this does not fix the problem, verify network coverage in your
location with your network provider. Check the Service type. If EVDO is listed, skip to the
next step.
2. If 1xRTT is listed, the Vanguard 3G unit has not found an available EVDO network. The
Vanguard 3G unit will provide network access when only a 1xRTT connection is available but
the speed of the network connection will be much slower. Contact your service provider to
confirm EVDO coverage.
3. Check the DHCP lease time. If this is set to a high value (>1000 seconds), skip to the
next step. If the lease time setting is set to 0 or a low value, reset to a higher value. Unless
you have a specific reason for limiting the lease time, this should always be set to the
maximum value.
4. If you have completed all steps above and still have poor network performance, perform a
speed test on the device to confirm the connection speed (example: speakeasy.net). If the
speed test shows acceptable download and upload speeds, the problem is most likely with the
specific Internet site you are trying to connect to and not the Vanguard 3G radio modem.
