Why do i get higher upload speed test results in the router speedtest itself with flexqos disabled? The download speed is always the same

Because stock Adaptive QoS does not limit uploads from the router itself (i.e. where the speedtest runs from). FlexQoS puts such traffic from the router in File Downloads by default, so it is limited by your QoS upload bandwidth value.

I had a quick question. why is it recomended to move Learn-from-Home to the bottom if customizing the order of the catagores but not if you choose a preset one? i usually customize but i wanted to keep things simple

You can't customize the priorities of the preset options. So how could I recommend to move Learn-From-Home in that case?

The rest of the explanation for moving Learn-From-Home was fully discussed recently in this thread.

Here it goes. Same IP, same exit port, different internal port. Different classifications - HTTP and Speedtest.net. Signatures?

I believe this has been covered in the past.

It's not recommended to use the presets because none of the preset options put the L-f-H at the bottom. So it's best to use the customize option instead.

so should i just always have learn from home at the bottom and dont make any iptable entries that point to it and just ignore it?

You should leave it at the bottom (or at least beneath both Streaming and Web Surfing; doesn't have to be at the very bottom as long as those two are higher priority). You can still use iptables rules if you want to put something else in Learn-From-Home since it will be otherwise unused.

ok cool. thanks man. sorry for all the questions its just these threads are so long its hard to sift through everything

What variant of Tomato are people generally referring to when they say “Tomato” in 2021? I ask because I want to see what their QoS code looks like to support domains. Shibby, Fresh, Advanced, blah blah blah. Maybe they’re all the same. I haven’t used Tomato since the Linksys WRT54G.

As I mentioned a couple posts above, if I add any domain name/ipset based features to FlexQoS, traffic that gets modified by such an iptables rule won’t show up in the correct priority class in the list of Tracked Connections. That tends to freak people out when they think the traffic should show up in one class (e.g. Gaming) but it shows up in another (e.g. Web Surfing).

did you ever get around to playing around with this? if i could also add domain names it would be the best of both worlds. i think now with fc and runner disabled the buffer bloat is pretty much the same as with cake (make +2 ot 3ms but thats it) but it seems snappier for my network usage then cake... or if its not super complicated just tell me how to do it i know the ins and outs of linux and stuff , no windows in this house!

Seems to be some sort of weird bug with QoS and Steam. For some reason, even when functioning well under cap it causes all sorts of latency issues and throttling among other programs while downloading. It doesn't do this with any other downloads or uploads. I have to manually set steam to 50%, even then it causes issues among other things happening on the network. Anyone have any ideas? Origin works fine, speed tests work absolutely fine, running OBS normally works perfectly fine, but when a steam download starts it wreaks havoc on the network, even under cap. If I turn off QoS and run manually with the built in Steam throttle the network functions normally.

Back when I used Tomato QOS, I traffic shaped Steam by taking their entire IP range and shaping ports 80 and 443 after 512KB of transfer. Turns out Steam downloads are typically HTTP - so they could get confused with regular web traffic and drop into a higher category than expected. Unless AdaptiveQOS has figured out a better way to detect and classify, they may be doing roughly the same thing as I did.

The main problems with this method:
1) The first 512KB are still Web-High priority. There will be a slight ping jolt as new downloads start unless you shape that category properly too.
2) Many games (like Guildwars) use HTTP for game traffic. It unfortunately also gets deprioritized along with the downloads.
3) IP ranges change over time. It's not guaranteed to stay effective even if you do get it working.

In my opinion all programs should use specific ports for specific tasks, and document it so that our lives are that much easier.

I looked at the classification of the Steam connections and it looks like it was getting categorized appropriately. What I did notice however is comparatively Steam seems to open and close a ton of connections while it's downloading. Basically it looks like it functions a lot like a torrent, only with more chaos. It's pretty interesting if you open it up in resource monitor and watch it. I think there might be some sort of weird bottleneck that's happening in the background due to the overhead this imposes. I can run download tests fine, Origin, you name it, it's just steam.

CPU utilization on the router while this is happening is much higher then a normal test or just torrents too.

 

[BikeHelmet]

That doesn't surprise me. They use a repository system, except more granular than what Linux typically uses. Your average game might have hundreds of repo entries, for different components and different versions. I don't think they torrent specifically, but they do spread the connection load around. They also download a lot off-peak... my download schedule is almost always between 3 to 7AM, which I assume it selected because 1) My PC is left running, 2) I'm not using my computer then, 3) North Americans aren't using Steam servers much then.

May I ask what router you have? I specifically bought mine for the powerful CPU, as I have found on weaker CPUs there is a long delay before categorization was applied. I typically leave torrents going 24/7, and have hundreds or thousands of connections established at any one time. Without a very fast CPU, forming new connections does get quite slow and laggy.

This is an ignorant question, but do I need FlexQoS if I upgrade my speeds to 1.2 Gbps down / 35 Mbps Up ? I may upgrade to comcast (xfinity) gigabit speeds. I'll be using a CM2000 modem with my RT-AX86U router.

 

[geobernd]

You get 42 Mbps (after 20% overprovision) upload. If you come close to using that and want to control how the bandwidth is made available to various things (e.g. Video Chat, Online Backup etc...) then yes.
On the download side it's not very likely you will notice a big difference unless you download massive large games etc... all the time

How many people are at your home? What do you do with your connection? That speed is very lopsided, so I lean towards "yes" if you are a moderately heavy user. But that said, the answer could also be "no" if you don't abuse your internet much, and/or have no other users present.

Here is an example - someone wants to open a website, but you have got torrents and a YouTube upload going, strangling the upstream. (Or DropBox! Or Google Drive!) Everything is slow and laggy and pages take 40 seconds to load on 1.2gbit. Shaping the upstream so that web traffic is higher priority allows requests for website data to go out more promptly on your 4 lane highway, and then return on your 120 lane incoming superhighway.

Some services and programs allow you to set speed limits. qBittorrent does, for example - you can set it to 70%. Dropbox is the same. This is great for a single user, but what if someone else runs something that consumes 70%? 70%+70% = 140%. Now you're back to being maxed out, redline, 100% for long periods of time, strangling other connections. QOS is the solution to this.

I personally would set the incoming speed (downstream) to 100% for every category since you'd have an abundance of that speed. Set the downstream very high, maybe even above your connection speed. You don't want incoming packets being dropped since few if any services can max it out and cause BufferBloat for you.

Fiddle with the outgoing (upstream) on different categories to get the desired traffic shaping effect for upstream. Put categories like Gaming, Web Traffic, Other, Streaming near the top. You definitely want to control what services in your home can do. A fire exit does no good if 40 people try to cram through at once rather than taking turns. The QOS will definitely help when programs like Dropbox, qBittorrent, and many others start hogging upstream. Keeping the smaller but more time critical requests going out promptly and regularly is important to maintaining a responsive feeling internet.

So I vote "yes" - but you could also go for "no" if it's just you, or you don't do much on the internet.

I have a AC86u. Should be plenty fast and works fine with normal torrent loads.

List of Asus routers - Wikipedia

Looks plenty fast for most regular workloads and most regular connections. Doesn't that model have AES support too? Hardware accelerated, so not much will slow it down. Probably a beast of a router for any encryption - VPNs, etc.

Dave. Someone on my twitter the other day suggested something regarding QoS and FIFA.
I have re read his suggestions but its clear half of it is way out of my zone...probably more tbh.

I said I would ask someone with knowledge and mentioned you.
I hope you can make sense of this lol.

Context was we were talking about me setting my Mikrotik switch LAN ports to 100 for the asus link and the console link...and gameplay was consistently better.
The guy chipped in with these comments...

"I've already tested these settings a while ago. I have a mikrotik RB760igs. Flow control gets worse because it slows down the delivery of packets. Physical limitation /100 on the network card is only temporary.

Try to equalize something about qos bfifo around 128000 bytes with low priorities and equalizing the total flow of the mother queue with the same value as well.

A big problem with the qos queues are the sizes. automatically the packets that don't fit there are discarded, so it's a good idea to set the packet size to a size used by the game at equal sizes with no queue limit. What has worked for me is the bfifo.

mark the udps packages in the mangle. Generate a 5mb up and 10mb qos only with udp pointing the mangle's marked packages to that qos. And use bfifo to line up for correct sizes. Going up to division 3 here. Feel free to send a direct message."

Now fifa's udp packet sizes are between 80-120...maybe a little more on certain udp packets.

I know you gave me instructions once on burst rates but this is different ??

Not really. Seems rather unintelligible to me. He may know what he’s talking about, but I don’t understand it.

I’d like to see someone (besides me) adapt this script for Merlin:
