Model: Archer T4U Plus

Hardware Version: V2

Firmware Version:

Hi!

My newly bought adapter provides me only with around half possible speed available through WiFi.
Full internet speed is 600 Mb/s. Through WiFi on phones or laptops - speedtests shows around 560-580 around the home, also in place where desktop with adapter sits.

Speed through adapter varies between 250 to 300. I've installed correct (v2) drivers from tp-link pages, turned off antivirus to check if it's blocking something (nope), I'm out of ideas how to solve this.

OS is WIn10, freshly updated.

Thank you for fast answer! link speed is set at possible max - 866 Mb/s I've installed these drivers, no visible upgrade to anything. My router from ISP is using WiFi 6 protocols and have 2 separate networks - for 2,4GHz and 5GHz. I'm ofc connecting via 5GHz one. Did some research - my PC is a little old now. MB is on LGA1150, DDR3 era. Is it possible that it's somehow not fully compatible with WiFi 6 and newest protocols and there lies my problem?
