Intel Wi-Fi6 AX201 160 MHz Bluetooth range too small and frequent disconnects

[BertRAMAerts]

I have a Lenovo Legion 5 15IMH05H 81Y6 laptop with Intel Wi-Fi6 AX201 160 MHz.
According to:
https://www.intel.com/content/www/us/en/products/docs/wireless/wi-fi-6-ax201-module-brief.html

Bluetooth® 5.1 provides 4x⁶ range over Bluetooth® 4.2 using the same Tx power, enabling coverage throughout the home.

My previous laptop had an Intel 8265 wireless module and had a range of 16 meters. My AX201 has a range of 10 meters with disturbances already happening at 8 meters.

All measured with my Sony WH-1000XM3 headphones. Working at my laptop so at 0.5 meter I have sometimes disconnects.

My laptop is mainly used with Ubuntu 21.04 with firmware:

sudo dmesg | egrep -i 'blue|firm'
[ 2.204649] iwlwifi 0000:00:14.3: loaded firmware version 59.601f3a66.0 QuZ-a0-hr-b0-59.ucode op_mode iwlmvm

But in Windows 10 the range is identical as in Ubuntu.

So what is wrong?

Dear Deivid A.,

I give up the discussion in this community forum.
My end conclusion is that Intel is not providing a linux service as good as Windows 10 service for the AX201.
Bluetooth range is much lower in linux than in Windows.

Therefore I bought a Veus Bluetooth 5 usb dongle (based on Realtek 8761b with correct linux support) of 20€ which gives me the bluetooth range I was used to with my previous laptop.
