hostapd: is possible to increase/reach a decent speed?

My nmcli report those speed on wifi routers

Code: nmcli device wifi list
Wufr1 Infra 44 270 Mbit/s 36 __ WPA2 WPA3
other Infra 11 270 Mbit/s 40 __ WPA2
other Infra 12 540 Mbit/s 37 __ WPA2
other Infra 2 540 Mbit/s 30 ___ WPA2
other Infra 6 540 Mbit/s 30 ___ WPA2the "Wufr1" is my AP with hostapd, why is limited to 270MB? Is possible to reach 540mb?
This is my hostapd.conf

Code: interface=wlan1

ht_capab=[HT40+][SHORT-GI-40][MAX-AMSDU-3839]This is the driver.conf for server

Code: options 88x2bu rtw_drv_log_level=0 rtw_led_ctrl=0 rtw_vht_enable=2 rtw_power_mgnt=1 rtw_beamform_cap=0 rtw_dfs_region_domain=1 rtw_switch_usb_mode=1and client

Code: options 88x2bu rtw_drv_log_level=0 rtw_led_ctrl=0The connection is stable, but speed is very slow
For example using rsync

machine3 can get 10MB/s (very poor)

machine1 can upload to machine3 at..5MB/s (awful)

Any advice? Thanks
