I have Intel® Dual Band Wireless-AC 3168 on ASRock B660M-ITX/AC. I read adapter spec up to 433 Mbps. My router have 5Ghz connection and 20/40/80 Mhz widh.  When connecting to WiFi, the maximum link speed obtained is only 86.7mbps at a very close distance to the router.

I tried it on another laptop and the result was that the laptop could get a link speed of 877 Mbps over a longer distance

I have also installed the latest drivers for Intel® Dual Band Wireless-AC 3168

Have you updated your wireless driver? If not, do a driver update. This may solve the issue if it is due to an old driver or a wrong setting. You can use this link to update your driver: https://www.intel.com/content/www/us/en/download/19351/windows-10-and-windows-11-wi-fi-drivers-for-intel-wireless-adapters.html

I’d like to know the following:

What is the make and model of your router?
Is this only happening with 5ghz network or 2.4ghz also?
Have you tried using different AP?
When running a speed test, what is the max upload and download speed you’re getting?
Have you check if the antennas are connected properly?

Kindly share the ssu logs of your computer. This will help us verify your system specs and driver version. You can follow the steps here: https://www.intel.com/content/www/us/en/support/articles/000008563/ethernet-products.html

Also, I would like to know if the wifi card is pre installed on your motherboard. I have checked the specs and it appears to be included.
