Please guys, i have this problem, i set up a point to multi point using RB433 but it works for a few hours and stops until it is rebooted. Also, how can i split the LAN cable to the TWO LAN PORTS ON the RB433?
What does log says after reboot ? Make sure you are using power supply with inaf output power, also install the latest RouterOS on your device:

If the problem repeats, generate supout file after reboot, and send it to support@mikrotik.com
