AX6000 Thotlling down selected software
I believe I've had this router for 2 years or so. Last month it started to throttle down some software on my PC, others still normal. For instance, my speeds are about 700 Mbps down, 50 Mbps Up. Speedtest app from Windows Store reports 700 normally, while speedtest website on Firefox reports... 14 Mbps. At the same time, Jdownloader, which normaly downloads at about 50 MB/s, downloads at... 1,5 MB/s. Speedtest on Microsoft Edge then reports around 400 Mbps... Upload speeds remain consistently at maximum.
I was using older firmware, but upgrading to 2021 firmware doesn't change anything. When I connect directly to the IPS's modem Wifi, speeds are at maximum in every software. Doing same speedtest via Andoid app on my phone or speedtest website, speeds are normal.
QoS in standard mode
no device with priority (tried giving PC priority, but did not work)
OFDMA off
Windows 11
Intel 11th gen, with WIFI6 AX201
TV and other stuff connected via Ethernet sem to be working fine.
I hope somebody can help. Thanks in advance.

Since this only happens on this specific Windows 11 PC, I would suggest checking and updating the AX201 driver version to the latest first, then rebooting both the AX6000 and the PC to monitor the speed again.
I believe the PC is connected to the 5G network of the AX6000 automatically, but I would still suggest you try disabling the Smart Connect on the router, create a different SSIDs for the 2.4G and 5G networks, then connect the PC to the 5G one, monitor and test the speed again.
You can also try modifying the 5G channels, choose one that is less congested, then monitor.

Thank you for your answer.
- AX201 driver updated
- Smart Connect disabled
- Has been operating with 5G and 2.4 G separated, both share the same results
- Changing the 5G doesn't solve, and through Ethernet I have the same results. It seems some sort of "filter" throughout all traffic of router.
I hope this clarifies. Pls let me know.

Is there any special software that is running on the Windows 11 PC, such as anti-virus software? Please try running the PC in Safe Mode, and test the speed without opening any applications, then confirm if the speed will be normal.
If you don't mind resetting the AX6000 to its factory defaults and reconfiguring it from scratch, I guess that would be worth a try, that will exclude all customized settings on the router, you can connect the PC to it and test the speed. You can then add the configuration back one by one to determine which one may affect the speed on the PC.

I factory reseted the router to no result.
Could it be that the ISP modem is doing the throttling on the AX6000? I tried to find a setting that could be doing it, but could not grasp what it could be. Reminding that when I connect the PC directly to the ISP modem all speeds at all apps are OK, at their maximum.

Nope, I don't see any proof does it point to your ISP also since you confirmed the PC can get a normal speed when it is connected to the ISP modem directly bypassing the router.
Have you checked all the settings on it already? Especially the anti-virus? Just to be sure, only this PC has this slow speed issue when doing the testing, right? I would suggest contacting the manufacturer of the adapter or the computer directly to see if they have suggestions.
