Hello. I have Mikrotik 951G router with latest Router OS 6.2 installed. I’ve connected Megafon M100-1 modem to it, made setup as you can see in attached images and setup NAT as action masquerade. Everything is OK, but modem hangs up when I try to download large files on high speed or test my connection speed at speedtest.net.
In addition. I tried to limit speed in queues. Speed was low but on maximum speed modem status was “terminated… hunged up”

Many attempts to fix it and no results. I’ll try to buy USB cable with external power. It’s the last possibility.
USB Hub with external power solved the problem.
