ASUS AX88U causes problems for others using internet if one device continuously do a 100G file txr

[Tech9]

Everyday, he download files like 100G to 200G.

You may need to get rid of this user...

 

[welim]

Unfortunately I cannot. It seems either the problem is with the file or with the router. Is it adnormal for the router to slow down other people normal usage like web browsing ? Sometime it crashes

You are dealing with a consumer device, so yes, not unusual. Even SMB devices can suffer, but with planning and a QOS that actually works, you can deal with the situation. With consumer devices ... best solution may be scheduling the download to off hours for the rest of the users.

I still feel this is a bufferbloat issue. It says to overcome this, need SQM feature. Even with high speed connection, bufferbloat can cause problems because its a latency issue. Not a throughput issue. This probably why when I limit it to 40mbps, it will still cause problem despite I have big bandwidth which Ive subscribe. Anyone know if ASUS AX88U has this SQM feature "? SQM = Smart Queue Management.

Are you using asuswrt-merlin firmware? Try using CAKE (depending on your paid speeds) or install FlexQoS. Let us know if this fixes the issue.

depending on your paid speeds

The OP pays for 3Gbps plan, their router is cutting it down to 940Mbps and with Cake will go further down to 300Mbps. The whole picture is perfect. And what we don't know yet - the ISP may have something called FUP or Fair Use Policy. It's usually in the fine print for residential lines. Downloads 100-200GB daily plus other household traffic on top may very well exceed the "Unlimited" plan. I wouldn't be surprised if the ISP is throttling the account. The bandwidth on residential ISP lines is shared and not exclusive.

@Kingp1n , is it to use the Asus speed test. Determine X upload and Y download. Then turn on Asus cake and put X and Y. The rest, the router will do the work?

If your speeds are what @Tech9 said, definitely don't use CAKE.

I would try FlexQoS, but with your speeds you don't really need QoS enabled.

Have you had your ISP checked your lines? As Tech9 mentioned you might be getting throttled by them.

@Kingp1n, do you have a link for me to reference on enabling flexOS? Is this better than Cake where you said it reduces my BW by almost 2/3.

In Asus GUI, I can see Asus Cake. But cannot find FlexOS

@bennor, thank you so much. Apparently after installing this, it didnt crash. Is there a way to classify GAMING as top priority so that it has the shortest latency ?

i meant to say flexQOS resolved the issue. Im using the default. I don’t understand why flexQOS not available and need manual install. Secondly, is there a way to customize the priority with gaming being the first since it requires the shortest latency

 

[bennor]

I don’t understand why flexQOS not available and need manual install.

FlexQoS is a third party addon script. One will typically use AMTM to install the script, or use the third party addon script's specific method of manual installation. Addon scripts are generally maintained by a third party software developer not affiliated with Asus. It is the capability to use these third party addon scripts that make Asus-Merlin firmware so valuable and a step above the stock Asus firmware.

See the Addons subform for more discussion on the various third party addon scripts.

PS: I do not use FlexQoS nor the Asus firmware's included QoS option. So cannot comment on how to adjust FlexQoS settings or options.

Thank you @bennor .
Can I ask you if it’s normal or not. During the heavy download, the ping is around 10ms and the jitter at 50ms. Is this ok and will be still fine for gaming ? The game is called “Counter strike 2”. I’ve tried using OpenNAT to enable this to hopefully reduce the effect.

 

[welim]

May I also ask. I just install flexQOS and use everything default and it helps with stability. I google and heard flexQoS must also disable Asus accelerator? In this thread, I was under the impression that CAKE required but not FlexQOS. Can brothers and sisters enlighten me? Much appreciated
