I still find it surprising it took about 20 minutes to complete this task. It seemed straightforward. Your guidance was really helpful. I ran a similar speed test using the same browser on Linux Mint booted from USB, and the results were acceptable—roughly 470 Mbps down and 540 Mbps up. This suggests my hardware (MoBo/WiFi module and antenna) is functioning properly, while the issue likely lies in software. That’s good news. Now what should I do? I’ve heard about potential conflicts between TCP/IPv4 and v6 protocols. I’ve tried disabling the box for IPv6 in network settings, but the outcome remained unchanged. If I turn off the IPv4 connection, it stops working entirely.
Most home users use IP4, not IP6, so you can safely disable IP6. Regarding Windows, it presents a challenge. First, confirm your Wi-Fi hardware is operating at maximum capacity continuously. Windows often powers down Wi-Fi devices unexpectedly, especially on desktops. Check the Device Manager and the Wi-Fi settings to verify power status. The relevant section should clearly show how to maintain full power for your Wi-Fi card.
Journey continues... Thank you for sticking with me. I appreciate your patience. Initially, I turned off TCP/IPv6 and the tests yielded consistent outcomes. Following your advice, I checked the Power Management settings on my WiFi module and disabled the power-saving option. No changes detected. Interestingly, after disabling that setting, my PC crashed with a blue screen immediately, though it restarted afterward and appears stable now. I've experimented with several fixes: switched to a 2 GHz WiFi signal instead of 5 GHz (my router supports dual networks), performed speed tests showing downloads around 100 Mbps and uploads under 15-20 Mbps, reinstalled the module after uninstalling it, and even tweaked network adapter properties. Still no success. I'm feeling a bit exhausted from all this troubleshooting. I plan to keep working on it tomorrow after work. Stay safe!
This matters, likely a crash dump exists in C:\windows (perhaps under a subfolder named "minidumps"). Upload it so I can analyze and identify the cause. This is expected. The recommended values are 2.4 for the traditional setting and 5 for the newer, faster option. Let's proceed.

Hey, me again. I have already installed latest WiFi module drivers from official Intel site few days ago. Double checked adapter model and all. I have latest drivers from 2020 November. Unless there is other "NIC drivers" that I am not aware of. I will keep dinging and let you know if find something interesting. Stay safe!
