Solution Slow speed on Archer AX50
Customers may encounter and report that the speed is slow or even less than half when connected to the network of the Archer AX50.
We here share a forum user’s case with the community that how he resolved the slow speed issue when connected to the Archer AX50 network.
Quoted from the user about the slow speed description:
“I recently had a Netgear R7000 on a 1000/550 connection and got around 650 - 700 Mbps when testing on fast.com and speedtest.net. Also tested via the android app at multiple times and on different computers at various times.
With the AX50 I get 340 - 350 Mbps on fast.com. Better results on speedtest.net, but that could just be because of different settings.
Does the AX50 throttle connections somehow?
It's clear that the AX50 for some reason is not performing like it should.
Any idea why this would be the case?
Atm no other devices are connected. What are recommended actions to take? Turn on/off WMM?
(There are no interfering devices in this area)”
We then guide him to check the QoS settings on the AX50 and found that the download and upload bandwidth don’t match the real speed he paid for. He modified the settings as we suggested, and he can get the desired bandwidth on the clients.
Step 1 Login to the AX50’s web interface page, go to Advanced > QoS > Application Priority, ensure it is on the Standard mode, check if the Total Bandwidth matches that you get from your ISP or modem. If not, please click the Edit button, tap Set Manually, and input the real upload and download bandwidth, then hit Save.
Step 2 Launch the Device Priority, ensure there is no device with the high priority (Priority is off/grayed out):

Hello
i am getting exactly the same issue with my AX50. I have my router conected to my gateway, in witch I have more than 300Mbps upload and more than 300Mbps download. But if I connect the AX50 to the gateway and my computer ethernet cable to the AX50, I am only getting arround 105Mbps upload.
I set the QoS with 900Mbps up and down and did not make any difference. My firmware is also updated.
I am at this point considering this device has a hardware limitation to go over 105Mbps. The Tplink support teams could not figure it out neither.
I will appreciate any advise.

@JF90 Have you referred to my setting steps in the original post? Please manually enter the bandwidth and disable the device priority, then reboot the router and test the speed again.

Router "TP-Link Archer AX55":
If the speed cuts, update the firmware to the current one, at the time of publication of this text and:
Turn off the "TX Enable" function on the LAN.
Optional: Enable Full 1000 Mbit/s duplex
(if you have an 8-core cable and speeds above 100 Mbit/s)
1. There should be a link to the photo here, but it is forbidden for you.

And you will be happy:

Hello from France,
Thanks for the tip, but ... What the hell is wrong with TP LINK ?!!! 3 years later that bug is still here, and wasted 4hours of my time , and i can't use QoS for that router i bought SPECIALLY FOR THAT !

Solution to the speed issue:
Tested on my Router AX 50 - Hardware version: Archer AX50 v1.0
I installed the firmware version: 1.0.13 Build 20230907 rel.67739(5553)
From:
Download for Archer AX50 V1.80:
Archer AX50 V1.80 - Archer AX50(US)_V1.8_230907
(Note: Yes I know, I have hardware Archer AX50 v1.0 and I installed version 1.8)
After updating the router with this firmware, perform a hard reset on the router.
The speed returned to its maximum.
Do not update the firmware to the latest version: 1.0.14 Build 20240108 rel.42655 -
The limitation speed problem occurs again with this latest version.
We will need to wait for the software developers to take the time to fix the issue.
