I am using the HL7618RD 4G modem and connect to the network via a PPP connection.
i rely on lcp-echo-failures to detect a connection has terminated
I am testing the cellular link by disconnecting the antenna.
Once the antenna is disconnected, pppd should observe lcp-echo-failures and send a notice of ‘No response to n echo-requests’,
However, sometimes we do not receive a notice (from the PPPD deamon) for the echo failures even till 15 minutes after we disconnect the antenna.
Has anyone experienced this or can recommend a solution ???
