TP-Link AC1200 QoS Help

[Zeezo]

I'm trying to set up QoS on my TP-Link AC1200 router, however, the router seems to only allow me to enable QoS if I disable NAT Boost. Disabling NAT Boost dropped my 1Gb connection down to a 100-150Mb connection. I tried my best to educate myself about the subject and stumbled upon OpenWrt/LEDE which should handle it for you. I didn't go through with OpenWrt though, because I had version 1 of the router, instead of the supported version 2. I'm hoping more knowledgeable people than I am can help me with this, because right now I'm pretty positive that this is a hardware limitation and I need to get a new router or a switch, but I am probably doing something wrong.

If you have a 1g connection do you really need qos? What do you want to do with qos?

 

QOS can be pretty heavy on a router, so you need something with a reasonble cpu to do qos at 1g, id personally leave it off here.

I saw QoS was a solution to bufferbloat following guides from openwrt/fast/dslreports. I play a lot of competitive first person shooters and I get a lot of hiccups in my connection because I'm often downloading something on my laptop (I'm guessing). My internet speed is more than capable of handling the bandwith and my laptop can only download up to 250 Mb/s because its receiver is pretty crappy so my PC should at least get the rest of my bandwith. The quality of my line is A+ but my bufferbloat hovers between B and A, which degrades from my gaming experience. I also noticed that when I do a speed test, my router CPU usage skyrockets to 85%+ which I don't think is ideal, it means it's barely capable of handling the speed from my understanding? I'm doing my best to make my connection as reliable as possible to be honest, and I'm guessing QoS is the first step

Im assuming if you plug your desktop into your modem directly you don't have issues in games?

 

What is your upload speed?

 

When you turn on qos, does the problem go away?

 

You should still have enough speed for  qos not to matter here though, unless its the upload that is causing the issue.

I just tried plugging my PC into my modem directly but when I do that, the router doesn't get internet and no amount of device restarts is fixing it so I might have to call my ISP tomorrow about it and see if I can only use one line on my modem. I also don't have the username and password for my modem to tinker with it.

 

My upload speed is 50-70 Mb/s and that has the most bufferbloat

 

When I turn on QoS, a new problem is created by dropping my internet speed to a max of 150 Mb/s instead of 1 Gb/s, since I MUST disable NAT Boosting.

The router hitting 85% CPU is not necessarily a problem, as how often is it going to be maxed while you're gaming?

Bufferbloat is also not necessarily an issue, if you're not maxing out your upload while gaming.

You have to remember, the speed tests which test buffer bloat DELIBERATELY max out your upload, in order to test for it.  So its a worst-case scenario, not a typical one.

Well you have to figure out if its a modem or gateway (Modem/Router combo). Yes some modems will have mutiple Etherent ports, as some Docsis 3.1 modems use those to help you acheive faster than 1 Gbps. Because they basically said fuck using 10 Gbps interfaces on consumer gear.

I found one How are they used? My guess is that you use link aggregation

any ideas?

 

Edit: I did some research and for now each port acts as a different wan connection. The ISP has two allow the second one.
