Packet loss situation

Hi, sometimes we get complaints from the customers that packet loss is happening.
In that situation, what is the exact problem ?

Or is there a way to check it on microtik web interface ?
And how to fix such situations ?

You should know where it is happening first. Expecting you do not have only one device in the path between the endpoints…

yes lets say customer #12 has just complained.
So how do we go about checking it ?

Traceroute first to see where the loss happens.

Sorry, Im new to Microtik, so I dont have that much idea and Im very much green to networking too.

So, let me know, how do I track trace this thing.

Are you waiting for me to make a google search for you?

I you need to GIVE support to your customers, you should better start to learn TCP/IP and networking fundamentals (this is not mikrotik specific). On this forum users can give hints to work with mikrotik stuff better, but you cannot pretend a base tcp/networking course :smiley:

By the way .. Traceroute is a diagnostic tool for tcp (see wik https://en.m.wikipedia.org/wiki/Traceroute). In mikrotik world this tool is obviously present and you find it in tools menu.

I just went to the tools > traceroute

Entered my website’s IP address and tested.
I got this.

How good or bad it is ?

Are you sure you have selected the right ip for link test?

I am getting this:

I tried entering my website URL to TRACEROUTE to , but it says invalid.

So, I went to who.is and copied the IP address of the name server and entered that.

Isn’t that the correct method ?

How do I trace route a website url, from Microtik tool then ?

Easily:

[user@router] > tool traceroute www.google.com

I guess this you are doing it on Microtik terminal, not at the Tools - Traceroute

It’s the same. You can use a hostname for the address, but not an url.
Traceroute is a tool to check connectivity and path to an ip/hostname, not a web service.

Okay I just did it.
See attached.
So, its good or bad ?

0% loss is good of course. But you have sent only 1 packet. Leave it running for a couple of minutes.

Its not running after that.
Do I need to add something more to the command to keep it tracing until I quit ?

You can use ‘count’ or ‘duration’ parameter

/tool traceroute 1.1.1.1 count=60

Did it, it stops, doesnt go till 60 counts.

See .

It stops if you press Q or Ctrl+C.
Try also the tool from winbox. Just type the hostname in the first field. There it doesn’t need additional parameters and runs until you press Stop.

Only if Microtik made the winbox for Mac :laughing: :laughing:
