One day, the AC9560 failed, reinstalling the firewood did not help, but it worked after I pulled it out and put it back into the laptop. After that, I decided to buy a new network card so that there were no problems. I took this for Lenovo ideapad s540 laptop. After installing the drive, they immediately pulled themselves up. The speed according to the tariff from Rostelecom is 890 mb / s, in the speedtest laptop it now shows 500-520 mbs according to the speedtest (on the old one it was 350-370 mbs. In general, I advise, especially if you have purchased a router with wifi 6.
