Regarding your question, downgrading to an earlier firmware version would reset the device to default settings and erase all current configurations. If you’re managing the unit remotely, this would result in a loss of connection, so it’s important to consider whether this outcome is acceptable in your situation.
Additionally, it’s worth noting that a similar issue was reported in an earlier firmware version here: RUTM51 modem disconnects several times a day, so downgrading most likely won’t resolve it. For now, I’d recommend holding off on that step. As soon as we have a temporary fix or recommendation from our R&D team, I’ll reach out to you directly via email.
Thank you again for your patience and cooperation, we’ll stay in touch with any updates.
Best regards,
