I am running latest Kong on my R7000 and my network consists of the following devices:
Quote:
Xbox 360
Xbox One
HTPC running 24/7 (local backups, torrent,...)
Laptop (Gaming + Working.. needs good ping)
4x Smartphones (Note 4, Galaxy A5, Nexus 6, Nexus 6P)
Printer (connected via WiFi)
3TB HDD via USB to R7000 as NAS
If I understood correctly then QoS gives priority to the device/service that I select. But that wouldn't be really relevant to me:
Quote:
I will only game on on device at a time (e.g. only Laptop or only Xbox).
My HTPC is automatically in "stand by" when I run games on any device (I made myself a little program for that).
The smartphones aren't that much of an impact for the rest of the network?
So what would I gain from QoS ?
All I could do it tell the router to slow down someones Smartphone-Youtube while my Laptop is running and using the whole bandwith?

What you gain even if using one device at a time, is consistency regarding latency.
Even if one device is using all the bandwidth, there will be a bottleneck of throughput somewhere in between the line from your ISP to you and since your ISP's routing equipment serves more devices at one time than your own network would, their network interfaces need time to manage all that traffic for customers. It is getting better with newer standards like DOCSIS 3.1 (if you have cable), but its still more than you could have if you traffic shaped your line yourself.
The traffic shaping portion of QoS essentially allows you to move this bottleneck to your router from your ISP's router, where it can control the flow of data by preventing elongated stalling of network packets in its network interface's/port's buffers.
This is why you set 80-95% of your download/speed when QoS is disabled, when you enable QoS. You'll lose a little off the max of your throughput from your ISP, but if you were to download a game and play an online game at the same time, the download wouldn't cause you to saturate your connection's throughput from your ISP and you wouldn't experience any latency spikes when online gaming (consistency). _________________ LATEST DD-WRT FW IS LOCATED HERE: https://dd-wrt.com/support/other-downloads/?path=betas%2F

Interesting
Are there any guides on how to create the "perfect QoS rules" for my network?
I guess they will depend on my devices and needs or is there one "simple" QoS-Template that works best for all?
I set it up on my R7000 a few days ago; so far so good. You can prioritize/deprioritize by IP, MAC address, interface or service name which gives you a lot of flexibility. There is no "one size fits all" setup as everyone's network is different. For example, I prioritized gaming, media players, video services and web browsing while deprioritizing download services like icloud/itunes, steam and bittorrent.
Here is a good post about it that I found helpful.

Here's my experience with Dynamic QoS.. it made the one computer in my house that needed bandwidth work great.. and it killed every other device in my house that tried to get any bandwidth for anything.
I turned it off and there was peace in the valley..
Even if you only use one device at a time, it is good to at least to enable for the traffic shaping portion since you could be doing something thats latency sensitive and downloading something at the same time (even on one device ).
Ye I just finished setting it up...although I am not sure if all the options from that thread/guide are still up tp date?
I am talking about HTB with FQ_codel ?
I have set the speed to 90% of my max up/down.
I have only set to use mac priority:
Premium: xbox, laptop-lan
Express: laptop-wlan, smartphones, htpc
Standart: Printer
Should I set any other priorities?
I agree with QoS causing morw CPU load, but I think the R7000 has the power to handle it?

Anyone ?
Use this test here to see if your bufferbloat value is good. If 'A' or better, you are set for the bandwidth limiting part of your QoS functionality.
Only way to test priorities (and like I said, if only one device is being used at a time, you won't benefit from this part of QoS much) is use two devices of different priority level at once and try to saturate your connection. _________________ LATEST DD-WRT FW IS LOCATED HERE: https://dd-wrt.com/support/other-downloads/?path=betas%2F

Piggyback post, is there a way to have multiple ports in a rule? Not a range, but two seperate ports (like 53 & 80 for example's sake).
Doesn't seem to be possible in GUI or CMD.
In short, no. The router treats each rule with a range of ports, whether that rule's port range is made up of one port or 1000 ports.
Make separate rules and just name them rule1 (port 53) and rule2 (port 80).
Oh I know I can do that. But I have ports far apart that I'd like to cluster into one rule rather than 8 or so individual rules.
So another example, something like 22, 80, 1683, 55342, and a few more all in one rule.
Apologies if I didn't make it clear enough.
Then what you are asking is simply a UI cleanup.
Not currently possible and most stock firmware even shows it this way. Suspect its due to the way the Linux network stack works. It can't process 'this port and this port and this port' when looking at a rule so to speak.
