Wi-Fi problem MediaTek MT7921 Wi-Fi 6 802.11ax PCIe Adapter

[Lopez_]

Hi!

I have a problem with this network adapter, MediaTek MT7921 Wi-Fi 6 802.11ax PCIe Adapter, with this driver version: 3.0.1.1317. I have a 1 GB internet connection. At its best, it reaches the speed shown in the attached image. However, normally it ranges between 450 Mbps and 550 Mbps. I am connected relatively close to the router with Wi-Fi 6, 5 GHz and on the 160 MHz band. With my mobile phone, I have a connection at the same distance from the router of 950 Mbps.

I have searched everywhere and still haven't found a solution or something coherent. I have been working with Chat GPT to get possible solutions to potential problems. I have tried countless configurations and it's always the same. I have tried to find the latest drivers for the network adapter, but I can't find anything beyond what I've installed. If anyone has an idea of what it could be, it would be welcome.

Hi @Lopez_ 

I can only indicate to use this version

3.5.0.61

The version you mentioned, 3.5.0.16, is that the driver version that should appear for me? I upgraded from 3.0.1.1317 to 3.0.1.1325 and there was no improvement.

Maybe I should uninstall the device and install the version you gave me?

try doing that

I uninstalled and reinstalled, and it's still the same. I still have the same driver, 3.0.1.1325, and the speed hasn't changed. I'm giving up; I've spent a long time trying to improve the connection without any progress. Every now and then, I spend several hours looking for a solution, and it's always the same. Thanks.

Go to windows settings, then go to networks and internet click on wi-fi and properties of your connection and see the speed of the link you have with your router.

The link speed is 1200 Mbps in the WiFi connection properties and also in the router, but the router detects that the estimated speed is 465 Mbps. Attached are screenshots of the Windows settings and the router page. The Windows screenshot is in Spanish because I am Spanish, and the router screenshot is in French because I live in France. The internet service provider is Bouygues Télécom.

Then it is either a router incompatibility or some QS bandwidth limiter that the router has misconfigured. The wi.fi is connecting to the router at its maximum power, otherwise it would have other values, this value changes depending on the signal.

On the PC, I found QoS and it is enabled, but I haven't seen anything like that on the router. I know I can create specific NAT rules for each device; I created one for the PS5 to open ports, but I'm not sure if it would have any effect on the PC.
