Tags: #Firmware Update #Bandwidth Control/QoS
Model: Archer AX3000  
Hardware Version: V1
Firmware Version: 1.4.2 Build 20250813 rel.52800(5553)

I have the Ax3000 Pro model.

 

After updating firmware, ran some bufferbloat tests with QoS on and off.  Noticed QoS is broken on this latest firmware.

 

Please refer to pic with bufferbloat testing.

 

Upload Active with QoS on is 271 ms

Upload Active with QoS off is 28 ms

Upload Active with QoS on  Previous firmware was 0-3 ms

 

I do not have a pic with previous firmware :(.

 

I cannot flash back to previous firmware....

 

Any beta firmware available?

Thanks to @David78907 for sharing.

 

Yes, we have released beta firmware for some Archer routers. Please click to learn more about it: What Can I Do If QoS Enabled Causes BufferBloat and High Latency on My Router After Firmware Update?

 

 @LGrizL, please confirm whether your router model is on the list and whether the beta firmware can help.

Hello @David78907 ,

Welcome to our community.


Currently, there is no available beta firmware. Can I know if not using QoS will have a significant impact on your network usage?

 

We have reported this anomaly to the relevant department and will continue to monitor feedback.

 

If possible, we would appreciate it if you could help us collect the following information to local support email:

  @Joseph-TP 

 

Thanks for looking into this as I am thinking about replacing this router and purchasing another brand due to lack of QC in checking released firmwares and making sure all features work the same. It looks like my isp gave me more speed. I am now 500 down and 25 up.  The tests on prior post I was 400 down and 10 up.

 

I will disable my windows tweaks to test.  I use this "netsh int tcp set global autotuninglevel=disabled" normally to get rid of my download bufferbloat but is has no effect on upload..

 

I will work on getting those logs over soon. 

 

Thank you for your time.

  @David78907 have exactly the same issue. Engineering looking into it apparently but will likely look at another brand if this can't be fixed. Can't roll back firmware after the last update either. So poor.

Looks like this beta fixed it!

 

--Beta firmware--

Thank you!!!!!!!!! I'm glad i didn't need a new router.

 

A+ in bufferbloat! It is working better than on old firmware.
