Spectre x360 WiFi Speed too closely linked to Power Plan Maximum CPU

[votn]

My laptop has the Intel AX201 160 MHz WiFi adapter. I am using it in 802.11ac mode. Running Win 11 with the latest patches, and drivers/firmware are fully up to date as well. I have Xfinity 1.2 gig service, but do not yet have the WiFi 6 capable router, hence using 802.11ac mode.

Like others have stated, this model laptop has a tendency to overheat when a Windows 11 power plan sets CPU maximum performance to 100% (plugged or unplugged). I work around it by setting the max to something under 100, i.e. 98. However, there is a terrible network performance hit by changing it even a single percent. It is quite a non-linear response. My 10+ year old Galaxy 8+ phone's NIC outperforms this considerably more powerful laptop.

Using Speedtest, at 100% CPU, download speed is consistently in the 400 Mbps range. Should be higher, but that's plenty for my needs. Change it to 99, and the speed drops by nearly half. This result is easily repeatable. 

I have HP Command Center installed, and it uses the HP Recommended setting. There is no speed difference using the Performance setting. Laptop came with Windows 10, and the problem did not present itself until after upgrading to 11.

Has anyone come across this, and is there a workaround? I have tried an external cooling pad, but they are too noisy.

Thanks in advance for any insight!

Bump...

All I'm looking for is acknowledgment the issue exists, and is being looked into.

My 2015 Acer with 6 GB RAM and embedded Broadcom 802.11ac running Windows 10 outperforms this system by over 100Mbps while on battery with max CPU set at 90% in the power plan.
