I am faced with this issue. I have a 4meg up/down fibre connection from my ISP, but when I run speedtest or bndwidth test from differnt sites, I get different and lesser bandwidth if I connect thru mikrotik but higher banwidth if I connect thru my laptop.
I am using RB 2011Uias as the router. Below are the snapshots of bandwidth test when connected thru mikrotik and laptop.
your help is needed please.
