ADSL router with cellular backup

Controlling the conformance of the connection
After installing and setting up the router, control the conformance of the connection:
Reception level
The reception level must be better than -90 dBm (two flashes of the reception level led indicator).
See the table below.
PING error rate
Each PING request must receive an answer.
Network response delay to a PING request
The response delay must be better than 500 ms.
If the delay is longer than one second, it means the network is overloaded or that the signal level is weak.
If the connection is not conform, change the position of the antenna or select an alternative service like
UMTS instead of LTE for instance.
