I have encountered strange problem. I got few MikroTiks in my LAN. The main router connected to the Internet is hEX (10.10.10.1). It has to bridges configured because of the CAPs reasons. Anyway, there are two other MikroTiks connected to it: RB2011UAS-2HnD (10.10.10.3) and RB951G-2Hnd (10.10.10.4).
Now, when I run broadband test between 10.10.10.3 and 10.10.10.4 it shows almost 1000 Mbps/1000 Mbps, but when I run the same test between 10.10.10.1 and one of these two other devices (10.10.10.3 or 10.10.10.4) it doesn't show more than 500 Mbps/500 Mbps. What might be the problem?
