Reboot the modem, wait 2 minutes, reboot the R3, wait 2 minutes and see if you have internet then. How are you determining the router is restarting itself?

Do you have it connected to a power extender or direct to an outlet? If an extender please try direct to an outlet. Otherwise do you have another power adapter you could try with?
