Off grid firmware update

if I’m using my ac300 to power my internet link, can I update the firmware? the machine will power off, so I’ll lose the internet connection during the update. is this a go or no go? thanks

Every interesting question, I downloaded the firmware update to my phone and used bluetooth to upload it to the AC200Max. So I never used the internet with the AC200Max.

I see it as a “go” because the update has to be fully loaded first. So when tbe AC300 applies the update and shuts down , it does not need to access the Internet again.

I see there might be some issues with the firmware update, so, since everything on mine works just fine right now, I’ll just leave it alone… : )

Where do you get the firmware?
