Hi, I'd like to configure my QoS settings properly so that my internet prioritizes League of Legends specifically on my PC, but that there's still some speed left for other users in my network to browse the internet with ease at least.

The situation is simple, my brother needs to be using the internet a lot..socializing or watching videos and whatnot...but even if he is simply browsing the internet, it throttles my MS in the game (league of legends to be exact).

After some research I found out that I need to configure my QoS settings to get that result.

My router as mentioned in the title is ZTE's ZXHN H108NS. I can provide as much information as humanly possible for this to happen. Just say the word. I believe this post will most definitely help a lot other users who want to do the same even for different games, so let's be as thorough as possible. Thank you in advance for your time...

P.S. Here is a screenshot of my router's QoS settings!

You will have to read the manual, i could not find one in english that had any information about he QoS.

It really depends what features it has. Some you can only do the applications other you can put IP addresses into groups. You then put the applications in high medium or low.

Still what does this even mean. How much more does high get than low. And most important it only controls OUTBOUND traffic. A overly simplistic example would be user 1 sends "netflix give me HD movie xxxxxx" then sits and watches the movie for 2 hours download 4m/sec. So for SENDING 35 bytes of data it can eat your connection for 2 hours. How does making the 35 bytes high or low or anything else reduce 4m/sec he is receiving. This is overly...
Not a lot of luck finding the manual for that router.

I suspect since this is not a high end router the answer is you can't do it. The QoS settings on most routers are window dressing that do nothing really.

You really can only control the data you send from your house to the internet....ie UPLOAD. This is seldom the cause of performance issue unless the upload value is extremely low. It is possible to a small extent to influence download rates by restricting upload rates but it only works for certain things.

Really only the ISP can do this. They must somehow know which traffic is important to you and then choose what to drop because it won't fit into the connection coming to your house. Technically it can be done but no ISP will bother to do it other than with large commercial accounts.

There are advanced routers that have the ability to limit incoming rates...ie download rates. This is really a hack that is dependent on a error recovery mechanism built into TCPIP and only works to a point. It takes a completely reverse configuration to what you are thinking to make it work. You do not priorities your game traffic you limit all other traffic. So say you wanted 1m for your game traffic and you had 5m download. You would limit all other traffic to say 3.5m this should leave 1.5m unused for your game.

The problem is that the way this actually works is if other users say send 4m your router actually receives this and discards .5m hoping the application will respond and slow down. Not all do and even if they do they soon try to run faster again. This is also why you pick 1.5m to leave 1m.

I suspect you will have to buy a different router to get these features and you can never be sure bit torrent seems to not care about lose it just keeps trying to get more and more and more.

Superficial or not...I'd like to know how to do it with this router. It is definitely possible...even as a simple low - high prioritize system. Yes, there is no manual I am afraid...but someone with expertise in such configurations should be able to guide us through it, I am sure. By the way, according to my understanding, this configures the connection speed your router will use for each application via the ISP...Is there a way to perhaps configure the general bandwith between two PCs?

This is overly simplistic but it only takes a tiny amount of outbound traffic to sustain a huge amount of inbound.
