Question

Hello. I have checked we questions in the forum, but there were no solution to this problem. Has anyone found the solution?

RUT240 has 4G modem connection only, both ports are switchd as LAN interface. Modem disconnects from mobile network sometimes every hour. Sometimes it stops working very often and comes backonly after electricity was turned off and turned on again. 

Log shows that port states switch UP and DOWN constantly:
