Hello. I have ATT fixed wireless internet and the speed can unfortunately fluctuate (sometimes significantly). They guarantee at least 1Mbps up and 10MBps down and for the most part it is above those limits. I am using a script and spdMerlin data to set the QoS bandwidth limits (with FreshJr mods) to try an account for those fluctuations. So, my question is, should QoS be disabled before running spdMerlin or will it not interfere with the speedtest? I don't want new limits that are influenced by the "old" or existing limits do I? Thanks.

I really don't know if spdMerlin interfere with the speed test, probably yes, but I'm writing to say that as you, my internet speed fluctuates a lot, as unfortunately I'm using 4G for internet access.
So, if you don't mind, I'd love to have the script you wrote to define the qos based on speed test. That would be awesome!

Sure, no problem. Let me clean it up a bit and I will share it. Please understand that I am far from being a good coder, but it is working as expected so far. It uses bash and bc as well as spdMerlin or course. I use cron to run the script approx. 3-4 times a day ... during each execution of the script I take the average of 3 (user definable) speMerlin values and then set qos_obw and qos_ibw to those average values.

Perfect!
I'm not a coder either but I try to develop everything that suits my needs, so...
If it works it's good :) thank you!

Maybe you can share to us all here :)
Really would appreciated.

I hope this helps somebody ... works ok for me. Again, I am not very proficient at coding, just needed something that works for me.

I'll give it a try! Sounds cool!

I just want to edit something - how can I call spdMerlin option 2 (use preferred server)? Because I need to force a specifically server where I know I can get my real speeds

Not sure, but maybe edit /jffs/addons/spdmerlin.d/config with your PREFERREDSERVER and make sure USEPREFERRED=true
 
Using same preferred server:
Running script with QoS enabled:
===== Averages: =====
Download Speed: 17.393 Mbps
Upload Speed: .650 Mbps

Running script with QoS disabled:
===== Averages: =====
Download Speed: 18.530 Mbps
Upload Speed: 3.746 Mbps

So, for me at least, having QoS enabled does appear to affect the Speedtest results.

I made some tests and I think it affects ....
Although my download speed is very unpredictable (sometimes 20mbps, sometimes 5mbps, sometimes the full 40mbps or even more), my upload speed is constant, capped to the maximum of contract - 10 Mbps.
And with qos on, in speedtest I usually get 5-6mbps. With qos off, I usually get the 10mbps

Something odd when trying to run! Screenshot attached.

Something odd going on with the script.
The script has been working ok for ages.

With DSLreports i can tweak it to get A+ A and A+ but recently its been simply A A A.
Now with online games this has made a difference...a very noticeable one too.
After tweaking the DL and UL no joy.

But switching to bandwidth limiter BINGO.
Back to A+ A A+ plus the latency to the nearest server is 20ms lower than under the script.

Gameplay is also noticeably better.

What are your internet speeds and can you post pics of your setup using bandwidth limiter? Thanks

Im on 100MBs symetrical....
I give minimal BW to mobiles...a little more to the ipad and use the same BW for PS4 and laptop....45DL 40UL.

This gives me A+ A A+.
