Intel AX201 and Wi-Fi 6 troubles

Good day! I have such a problem: I have a Lenovo Yoga C940 laptop with an Intel AX201 160 MHz card. The day before yesterday I purchased and installed a new router that supports the Wi-Fi 6 protocol (cable connection 800 mb/s).
The situation is as follows - the card in the laptop does not support the AX protocol (Wi-Fi 6), regularly spontaneously resetting itself every 5-6 hours of operation to the AC mode (Wi-Fi 5). At the same time the laptop is motionless, the modem too. They are in the same room, there are about three meters between them, there are no walls in the way.
The problem is solved (temporarily) by disabling and re-enabling the settings in the network card driver. After a few hours, the situation repeats itself.
The latest driver version is, installed using IDSU.
I ask for help.

Please contact the router manufacturer to confirm you're running the latest firmware and the optimal configurations for this network. If it doesn't get better after that, please try a Clean Installation of Wireless Drivers:
