Hello @sitloongs,
Thanks for getting back to us and supplying the link to the update process.
So I can see we need to update the firmware in this unit.
We selected “Update All” for this MAX Transit DUO

and waited a bit over 10 minutes to see if it would work and selected “Check again”, hmm looks like it did not work.
So we then did the two modems individually.
Modem
#2 first
Followed by modem
#1
What we also found is that the Status does not update, you need to manually select “Check again” to see the status, if you attempt to check during the update, we found we got this message

returning you back to

Once completed we had this
From our experience and based on the logs each modem realistically takes about eleven minutes to update and return to service. Also we needed to do a soft reboot after the upgrades as the modems would not accept configuration change requests (such as being asked to do 3G only when previous set to LTE only).
We hope this information is of benefit to other looking at the same process.
Out of interest, where does the update firmware come from, is it already on the device within the currently loaded Peplink Firmware or does it need to sourced it from the web each time?
I’ve got to ask, though why is the modem firmware update not done as part of the rest of the system update? In a multi modem device (eg. BR2, HD2, HD4, EPX) could these be updated in sequence as part of the upgrade process (one modem at a time) so to minimise link down time, and where the modem is being used for standby or backup, could it not be automatically schedule to update while the rest of the system runs on the other WAN connections?
I’m sure many people here would appreciate some education on why this is done this way. Our team have plenty of experience from the past with other vendors and chip sets, though it would be good to have Peplink’s official reasons.
Appreciate your assistance,
Marcus
