Intel AX210 cuts speed, how to fix?

Question

Computer networks

Hello. I bought a fenvi network card on an Intel AX210, but the 5GHz speed is very low. Even at 2.4 GHz it is 1.5-2 times higher. The drivers are the latest from the Intel WiFi-22.100.1 website. I can’t put it below because an error comes out that a newer version is installed. How can this be fixed? 1 screen 5GHz, 2 - 2.4GHz

Answer 1

You need to measure not with a speedtest, but iperfwithin the local network.
Have you tried changing the 5GHz channel? Or are you free?

Answer 2

Where is the router located? how far? What walls? What level \ speed of the signal is shown on the Wi-Fi on the PC? Is the 5Hz channel blocked? how strong?
other drivers can be installed by first deleting the old ones along with the device in the task manager

Answer 3

Very high ping inside the Rostelecom network, on Wi-Fi next to the router in such a config, the ping should not be more than 10, but what kind of router?
