System: Balance 30 LTE, firmware 6.3.2s027 Configuration: WAN1 = Satellite, Wan3 = Cellular, with AT&T and Verizon SIM cards
**Carrier connections: **Both are LTE, Verizon pretty good (RSRP at -70), AT&T OK (RSRP at -85) Observation: Autoswitching from one SIM card/carrier to the other (e.g., when changing from the preferred to the non-preferred) takes approx. 150 seconds.
Question: Is the 150 seconds lag (break in connection) normal for such a switch?
The time-out was set to one minute - that minute is not included in the transition time.
The event log (the change being to make SIM B the preferred SIM):
Nov 11 19:32:37 WAN: Cellular connected to AT&T (10.239.119.88)
Nov 11 19:27:30 WAN: Cellular disconnected (No device detected)
Nov 11 19:27:15 WAN: Cellular reaches failback timeout, switching to preferred SIM B
Nov 11 19:26:47 System: Changes applied
Looks like it took some five minutes this time 'round.
Please find my testing below. The only different is the time used to connect to the ISP. My device uses 33 seconds to connect to ISP. However, your device uses 5 minutes 7 seconds. The time used to connect to ISP is depending on the environment.
If you wish to know what is happening within the 5 minutes 7 seconds, please replicate the problem again (I believe the previous log was overwritten since it was happening on 11 Nov). Then download the Diagnostic Report and submit us a ticket.
I am ok with the delay - it is not critical for me. Unless you think there might be something wrong (or something useful to your development team) I’ll eave this one be for now.
