Does router OS throttle WAN speed ?

Hi
I worked somewhat with mikrotik products many years ago, and recently dusted off my RB1200 unit. I have upgraded to ver 6.37.1 (stable).

Everything is working as it should, but my download speed seems to cap at about 2.5-2.8 MB/s mark, With my previous router I easily had 4-4.5 MB/s.

I have disable UPnP and NAT-PMP, and done a manual portforward (both tcp and udp), which also seems to be working fine. All except for the lack of speed…

Any ideas ?

  1. post your config
  2. how are you testing this speed? have you tried other methods?

Since this device can easily handle Gigabit WAN speeds, there must be an answer in 1. or 2.

Hi, and thanks for yor response. Please be patient, as I am somewhat rusty with both winbox and CLI.

  1. The speed is coming from utorrent (only legal files, of course :slight_smile: ) Also all other utorrent settings are the same as with the other router.
    I have now also tested the speed via speedtest.net, and got the following results: Ping 16ms - download 40.83 Mbps - upload 40.60 Mbps (these values correspond with my Internet service subscription)
