ParticipantI Use Zeroshell since version 1.3. now I have a 3.9.1
As a backup I have always used a 3G T100 modem with LAN output and
I recently added a 4G USB modem (Qualcomm 4G LTE Modem) to replace the T100 (3G).
The problem now is that at 02:00 it disconnects from the network and reconnects at 07:00
The time zone doesn’t matter.
There is a keep alive script that ping 3 different IPs every hour and active failover.
Nothing to do, every day at 02:00 to disconnect and at 07:00 to reconnect.
I have not found options for energy saving, neither in Zeroshell nor on the Modem.
The provider says the problem is not on their part (obvious),
and the line: <Terminating on signal 15> makes me think of Zeroshell,
but no reboot occurs at 02:00 (no notification from monitor)
I am perplexed about what happens at minute 00:02:35,
it seems that it reconnects, but no data is passing through …
In fact at 00:07:18 it says received 0 bytes
Thanks for any ideas or advice!
The Log of a typical day follows:Uso Zeroshell fino dalla versione 1.3. ora ho un 3.9.1
Come backup ho sempre usato un modem 3G T100 con uscita LAN e
recentemente ho aggiunto un modem USB 4G (Qualcomm 4G LTE Modem) in sostituzione del T100 (3G).
Il problema ora è che alle 02:00 si disconnette dalla rete e si riconnette alle 07:00
Non importa il fuso orario.
C’è uno script keep alive che fa un ping su 3 IP diversi ogni ora e il failover attivo.
Niente, ogni giorno alle 02:00 disconnettersi e alle 07:00 riconnettersi.
Non ho trovato opzioni per il risparmio energetico, né in Zeroshell né sul Modem.
Il provider dice che il problema non è da parte loro (ovvio),
e la linea <Terminating on signal 15> mi fa pensare a Zeroshell.
ma non avviene nessun reboot (signal 15) alle 02:00 (nessuna notifica dal monitor)
Sono perplesso su quanto avviene al minuto 00:02:35,
pare che si riconnetta, ma non transitano dati…
Infatti alle 00:07:18 dice received 0 bytes
Grazie per ogni idea o consiglio.
