Internet become slow when uploading via FTP to Outside network

RouterOS General
1

I am using RouterBOARD 3011UiAS with 2 ADSL broadband connections (both are from same company).

Problem: Our internet become slow whenever someone is uploading file to outside network via FTP. This is happening from last 10 days. I haven’t change anything in Mikrotik Router. I have logged complaint to ISP and he has visited my place and said that there are some problem in your Router configuration.

Hi,

And welcome to the forum.

First Question.

Is there load-balancing between the 2 dsl connections?

Second Question.

What is the upload speed of the 2 adsl connections and does the ftp upload speed comes close to that?

There is no load balancing…One is 8mbps and second is 40mbps

Put a queue on the ADSL interfaces that limits the upload speed to slightly less than the actual speed
you are getting on the connections (do a speedtest first).
When you want to get really savvy use one of the scripts that creates a queue tree for different
priorities derived from DSCP, you can find them on this forum. But a single queue with upload
limit should already help a lot!

I am not much familiar with scripts!!!

Then do not use them!
Just make a single queue for each interface.
