AXE16000: only 550Mbps via wifi6E 6GHz

Level 7
Hi everybody.
From my ASUS GT-AXE16000 i get only about 550 Mbps download speed via wifi 6E 6GHz to my HP Spectre x360 14-ef0003nl notebook. Via Ethernet cable i get over 2,2 Gbps. Firmware is (but i got the same results with the previous firmware). Via wifi 5Ghz i get the same speed or slightly less. Network card is Intel AX211 with latest driver. Win 11 wifi properties says link speed is 2,4Gbps UL/DL.
I believe i should get at least 1 Gbps via wifi6E 6 GHz.
Any ideas about what i should try?

Make sure the router settings under WiFi Channel bandwidth that they include "160 MHz", for 5 GHz there is also a checkbox for it. But I believe for 6 GHz this is enabled by default?

Intel provides a driver update service for you to check if you have the latest Windows drivers:

Are you trying to transfer some data for the speed test or an online speed test? If you are using data, what type of file is it?

The Link speed is usually a good indicator of what the transfer can be, but real-world experience may vary.
