Eudemon 200E-X1AGW-W failover failed

Publication Date:  2014-11-09 Views:  326 Downloads:  0
Issue Description
When we setup the router for our client who we want the router to have 3g failover but the failover is not working correctly,
Often I will find that the 3g is not connected or has been on for only a few minutes at a time. The online mode is set to “always online”
As a failover I find that this is not reliable.
Alarm Information
none

    Current register operators:65501  3G
    Quality of signal:-103 dBm


Root Cause
Quality of 3G signalis only only  -103dbm. The larger the absolute value of quality of signal, the weaker the signal. If the absolute value is larger than 90, the signal is considered weak. If the signal is weak, adjust the direction of the 3G antennas or the location of the device for stronger signal.
try and display cell regis find the signal again
Solution
after changing the position and displayed that command:

<HATZOLAH>display cellular registration
10:46:35  2014/10/22
    Current register operators:65501  3G
Quality of signal:-85dBm

failover working fine and 3g card giving internet access successfully
Suggestions
he larger the absolute value of quality of signal, the weaker the signal. If the absolute value is larger than 90, the signal is considered weak. If the signal is weak, adjust the direction of the 3G antennas or the location of the device for stronger signal.
