Enabling QoS for an internet game

[drtgj]

My router is ADBB P.DG A4001N. I have found the manual here http://www.manualslib.com/manual/629328/Adb-P-Dg-A4001n.html?page=60#manual , but it seems to have a different interface than the one I have.

The purpose is to have my ping not spike up in-game while I play Dota 2 when somebody loads up a video or downloads a file.

I have three computers always connected to the router, a printer and sometimes a laptop / some smarthphones connect via Wi-Fi. I'd prefer to enable QoS without installing another router OS if it's possible.

I have 4mbps down and 0.56Mbps up, I hear QoS doesn't work too well with such low badwidth, but trying can't hurt can it?

Here's how the menu looks for QoS Queue (which as I understand is the same as prioritizing, isn't it?):

I can't see the option for port and don't know what to put down in the other options as well. Is this menu comprehensible for anyone?

As always, thanks for any help in advance.

There are likely other screens that allow you to select traffic to apply the rules to. Hard to say without lots of reading.

It is likely a waste of time to even mess with it. You can only control data your router sends...ie upload. If your problem is download the ISP has already decided what it wants to throw away and by the time your router see anything the data is gone. Some very advanced QoS configurations can drop even more traffic after you received it in hopes the offending application will see it and slow down.

You router does not appear to be able to even attempt that type of configuration.

Thank you for a thorough answer! In hopes it's still possible and not in the menu, here are the other QoS options https://www.dropbox.com/s/dr8t6lkkwydiwva/QoS%20options.bmp?dl=0 .

Is anything worthy there?

The feature you need to find is one that limits inbound traffic to a hard fixed limit.

What you need to accomplish is say your game needs 2m what you need to do is limit all other users to 2m which will leave 2m unused for you.

It would be nice if you could put rules in that say "all other users" but it is never that simple so you will have to dig to find a way to do it.

Most QoS configurations are designed to match a ip/mac and then give it priority. In this case we want to do the reverse.

All this complexity is because you technically can't do what you want with QoS, only the ISP can because QoS is really done on the sending side. What a configuration like this really is doing is causing a error recovery method in the PC to slow themselves down...hopefully.

Be warned that even if you get this to work you will limit your connection for all the other machine to say 2m even when you game machine is not using the internet. I suspect with such a small connection you are going to get complaints from the other people because you will have in effect completely blocked their ability to stream high def video.

Okay, so I don't think that exists in the options given. Thanks for the help.
