A.2 Failed GPRS Connection
If the GPRS connection in the device is failed, the light-up order of the LEDs and time
interval between each state is very critical information to check the cause. There are
two possible scenarios for failed GPRS connection.
1. If you meet the following scenario, the possible cause is the ping action can not
reach to target. We suggest that you can check the content in Ping Target field
of GPRS/3G configuration page. We suggest you can change the content to
public server, such as www.google.com.
2. If you meet the following scenario, the possible cause is authentication failure.
We suggest you can check the Authorisation, Username, Password, PIN Num-
ber, APN and Phone Number in the GPRS/3G configuration page again. If you
are sure those fields you key-in are right, please contact your ISP provider to
solve it.
