windows 11 perrormance is less than half of windows 10 - 36MB/s

in windows 11, force in driver advanced setting to use 802.11/AC mode, can tempararaly increase the performance to 63~66MB/s. but after a while or restart. the performance reduce to 36MB/s

Is this a new computer?

When did you build/purchase it?

Was this issue happening before in this specific machine?

If not, when did the issue start?

Did you make any recent hardware/software changes, besides updating the driver and testing Windows* 10/11, that might cause this issue??

The wireless card, did you purchase it separately or did it come installed on the computer?

Hi colin_wang, You are very welcome, thank you very much for providing that information and the SSU report.

Based on the information shown in the SSU report, we can confirm that the wireless driver version currently installed in your system is 22.150.0.3, which is provided by Intel®:

https://www.intel.com/content/www/us/en/download/19351/windows-10-and-windows-11-wi-fi-drivers-for-intel-wireless-adapters.html?wapkw=ax200

It is important to mention that we always recommend to install the wireless driver provided by the board's manufacturer since that driver was heavily customized by them to work with your specific platform.

I looked at AsRock's website and the latest wireless driver they have available is version 22.70.2.1G. Please try a clean installation of that driver following the instructions in the links below:

https://www.asrock.com/mb/Intel/Z390%20Pro4/index.asp#Download

https://www.intel.com/content/www/us/en/support/articles/000022173/wireless.html

We also suggest updating the BIOS to the latest version. If necessary, you can always get in contact directly with AsRock support to gather the instructions on how to do that:

https://www.asrock.com/support/

If the issue persists after that, in the following link you will find the Advanced Intel® Wireless Adapter Settings for you to test different configurations, like for example both bands s 2.4GHz y 5GHz and different "Wireless Modes":

Once you get the chance, please let us know the results.

Hi Albert,

Thanks alot. 

Before upgrade the MotherBoard BIOS, the BT (bluetooth) device even doesnt exists.

after upgrade the MB BIOS, there is a new option in the bios to enable/disable onboard BT. I have enabled it. now I can see bluetooth working.

using either old (from Asrock) or new driver (from Intel) the LAN transfer speed issue is still the same. 

but the good thing about now is, I can toggle BT on/off (no matter from on to off or from off to on), that will increase the LAN trnasfer speed from 35MB to 69MB/s. 

as the screenshot shows, that 'speed climb' is the result of the toggling of BT. (toggle back wont decrease the speed)

althoug it's still slower than the speed in windows 10 (79MB/s). and need to manually toggle a swtich everytime... I can take that.

Hi colin_wang, You are very welcome, thank you very much for sharing those updates and the picture.

Excellent, we are glad to know that you were able to update the BIOS and that after that the option to enable/disable BT became available. It is also great to hear that by toggling with the BT feature, the LAN transfer speed increased from 35MB to 69MB/s., even though, as you mention, the issue is not completely fixed, it is a big increment in speed.

We are happy to know that we were of help in this scenario. Any other inquiries, do not hesitate to contact us again.
