I Just upgraded 3 of my RUT950 to 5.03.3 firmware and sms utilities command started not working. I inspected the logs, interestingly device shows "reboot: sms received from number" but router is not rebooting, but breaks internet connection and stays as it is. i'm receiving the reboot status sms after 03:00 timed auto reboot. Status command works fine but reboot command is not working. i have 3 remote locations and sms reboot is very important to me, because almost everyday device needs to be rebooted even device reboot itself at 03:00 in the midnight.
all of my 3 devices stopped responging after upgrading to 5.03.3 firmware so i think it is a firmware issue.
ps: bootloader is 3.0.1
