Intel AX200 Wi-Fi 6 Low Speed Issue and Troubleshooting (MSI X570 GAMING PRO CARBON WIFI)

Hello,

As I mentioned in the title, I have an MSI X570 Gaming Pro Carbon Wi-Fi motherboard. This motherboard uses Intel's AX200 Wi-Fi 6 network adapter.

I have a 1000 Mbps internet connection at home, and based on the speed tests I performed on the 5 GHz network with my phone and laptop, I can easily see speeds above 800 Mbps. My ping values range between 2 and 10.

However, from the same location in the house, when I test on my desktop computer, I occasionally see speeds around 250 Mbps (with ping between 2 and 10), but most of the time, I get results around 50-150 Mbps (with ping over 30). It's unlikely that there’s an issue with the device provided by ISP since all my other devices work flawlessly.

I’ve tried different versions of Wi-Fi drivers and applied many settings suggestions I found online through Device Manager. Unfortunately, I haven’t been able to solve the problem.

I’m awaiting your help. Thank you.
