Re: [Signals] SB6121 new firmware messed up my upstream! Another possibility is that a system issue is occurring and as a conseqhence of it, the modem lost sync, rebooted and updated it's firmware. Possibly the firmware update is not related at all to the issue. Call for service.
You're right that's a possibility. It was around 3am when this happened it could be that work was being done and something might have effected the signal levels.
Is it at all possible that my unpowering the modem during its first attempt to update the firmware screwed something up? Even if it managed to update on its second attempt?
Maybe, but it should recover after a "Reset to defaults" IF left to do it.
I really doubt the firmware update changed the power level, but the powerlevel could mess up the update, and the way the modem calculates the correct power level MIGHT have bee adjusted, but I didn't see that happen here.
im having the same issue
