FlexQoS FlexQoS 1.3.2 - Flexible QoS Enhancement Script for Adaptive QoS

[Kingp1n]

I usually put Gaming near the top, with reduced max bandwidth to stop a mis-categorisation playing havoc with things. (For example, a game download ending up in that category. Downloads can hog 100% of a connection.) Keep in mind that many games do NOT require much bandwidth to play. I have seen a lot of games that work on 256kbit-1.5mbit just fine. If you can grant them even a dedicated 20mbit, you're probably good for 99% of games. And a dedicated 5mbit will cover several users for > 90% of games. Some of the most popular games out there on Steam run fine on 1mbit or less. (It needs to be stable, though, so being categorized near the end would not work well.)

My current problem is that an XBoxOne is escaping FlexQOS entirely and hogging the entire connection for downloads. Under Traffic Analyzer -> Statistic, I can see the XBOXONE device chugging bandwidth at an insane pace, yet FlexQOS insists only 8 out of 30mbit is in use (in "Web Surfing" - mostly the XBox One)

I seem to remember a thread mentioning some bugs related to the RT-AX86U and its gaming port, and stuff bypassing qdiscs. I skimmed it a while back, but something in the back of my mind is telling me to go find it, as there might be useful info there.

@BikeHelmet


Did you ever made any adjustments to the original settings you had? Just wondering if you're still using Flex and if you were able to fix the Xbox downloads issue? Any info is appreciated!

EDIT: Figured this out, somehow gaming device was on.
Before I factory reset, figured id ask here real fast if any has had the problem/knows a fix. This is on my ax86u. Category order is Net Control, Streaming, work-from-home,web surfing,gaming,file transfer, learn from home, others.
If something is streaming, it will show in the work-from-home category.. If you set a client to net-control it will show up in streaming if this makes sense. Basically it always shows in the next priority category. Not sure if its really hurting anything.

I have setup QoS with 500/500Mbps on the AX86U.
Without QoS it works 540/540Mbps, with QoS 540/404Mbps. Any idea why?

spdmerlin is set to be excluded from QoS, plus CPU & RAM are not stressed at all.

On the AC88U was due to the CPU, but here, no idea.

Thanks,

Download isn't subjected to QoS at all with an on-router speedtest, so that's why it matches your non-QoS measurement.

I don't know what is a reasonable expectation for uploads from your router. Maybe others can share their experiences. Is upload the same on a true speedtest from a LAN client?

Same happens doing it with a wired PC uploading a file into Mega.nz for example. with QoS uploads reaches 420mbps like capped, and without QoS 500mbps easily.
Apart from that FlexQoS works excellent.

I am still using FlexQOS. I have not had issues recently, but that doesn't mean much. Due to life getting busy, I haven't been around as much at the same time as lots of other people. Also, we doubled the internet speed when the option came up to do so at a good price.

I have noticed the rare thing will still hog the connection quite a bit, making those minimums extra important - it's usually something dropping into the Web Surfing category, lately. I'm considering dropping its allowable downstream below 100%.

I think this is a case where traditional QOS with its bandwidth tracking works far better. It catches those bulk downloads nice and quick. But FlexQOS is so easy to set up, and categorises so much without any effort - it's pretty impressive how well it works. I should probably try out CAKE sometime, though - that way I'd have a good view of the entire QOS landscape.

Thank you @dave14305. Flex helps me not shout at my children.

with 386.5_2 I have this but not sure if its FlexQoS or the firmware. (already tried rebooting the router and installing FlexQoS again)

It appears you are a victim of flatlineQoS, flexQoS's primary competitor; in this particular instance, all categories are not deviating.

His upload is dead? But the download is still striving for speed?

Odd. What’s the output of tc qdisc show root ?

 

[SomeWhereOverTheRainBow]

Yea, no dice. Mine appears to be working fine after updating to the new stable Merlin. This leads me to question if somehow something is corrupt or has changed in regards to QoS on certain model routers.

Hi @dave14305

Just a quick question, I have searched the forum, and I know its somewhere, but I can't find it.

Can you remind me the optimum settings for upload and download bandwidths?

Is it 90% of actual? (My actual is 540/33)

Thank you for your help.

 

[dave14305]

Can you remind me the optimum settings for upload and download bandwidths?

The starting point to determine your ideal bandwidth settings is usually 90% of your actual bandwidth. Then keep testing higher or lower until you get your desired bufferbloat results.
