How do I open a ticket with Mikrotik? Has anyone had any success with the DHCP-Client Issue? I am no longer able to pull an IP address from my ISP on the WAN Interface.

Thank you so much for this! I have 940mbps/35mbps cable using a RB4011 router. When applying the optimized QOS, I see better results at dslreport's bufferbloat test, but my overall throughput is much lower, around 500mbps. Is there a way to have QOS and still have close to line speeds with this mode...
