The desktop Wi-Fi performance is significantly slower compared to a laptop.
Your computer is experiencing much slower internet performance compared to your laptop, even though both are in the same location. Your laptop consistently shows speeds of 40-60Mbps download and 1-10Mbps upload, while your desktop is only 5-10Mbps download and 1-5Mbps upload. The Wi-Fi signal appears strong (2-4 bars), but it’s not delivering usable speeds.
You’ve used several troubleshooting steps: reinstalling drivers, changing network settings, switching wireless modes, adjusting auto-tuning, and even rebooting the system. These changes have helped a bit, bringing your desktop speed up to around 20Mbps on Speedtest.net after some adjustments. However, it drops back down to about 5Mbps when you restart.
Your laptop uses an Intel Wireless AC-9560 card, while your desktop has an Asrock B550M-ITX/AC chipset with the Intel Dual Band Wireless-AC 3168 chip. The latter is a newer, more powerful chipset, which likely contributes to better performance.
Given the recent upgrades and the persistent issue, it might be worth checking if your laptop’s card is still compatible or if there are firmware updates available. If not, replacing the Wi-Fi card in your desktop could be a straightforward fix. However, since the speed difference is significant and hasn’t improved much despite your efforts, you may want to consider contacting support for either device or exploring a replacement part.
