hostapd: why only 65mbps?

Question

compare my router fritz with raspberry pi4 + hostapd

IN-USE  BSSID              SSID         MODE   CHAN  RATE        SIGNAL  BARS  >
        *****************  Fritzrouter  Infra  1     260 Mbit/s  100     ▂▄▆█  >
*       *****************  Rasprouter   Infra  7     65 Mbit/s   69      ▂▄▆_

As you can see the fritz router has powerful signal and rate, hostapd only 65Mbit. Is not possible to obtain more?

This is the hostapd.conf

interface=wlan0
bridge=br0
driver=nl80211
ssid=Router2
hw_mode=g
channel=7
macaddr_acl=1
accept_mac_file=/etc/hostapd/accept
auth_algs=1
ignore_broadcast_ssid=0
wpa=2
wpa_passphrase=mypass
wpa_key_mgmt=WPA-PSK
wpa_pairwise=TKIP
rsn_pairwise=CCMP
country_code=IT
ieee80211n=1
ieee80211ac=1         
wmm_enabled=1

Is your WiFi MTU 1500? See ip link. It should be 1492, or you'll spend a lot of time doing packet fragmentation/reassembly. — waltinator, Jul 11 '22 at 00:03

Solution found, with a good adapter and a good configuration we can reach good speed.

wlan1     IEEE 802.11AC  ESSID:"MMMM"  Nickname:"WIFI@RTL88X2BU"
          Mode:Master  Frequency:5.18 GHz  Access Point: *******   
          Bit Rate:867 Mb/s   Sensitivity:0/0  
          Retry:off   RTS thr:off   Fragment thr:off
          Power Management:off
          Link Quality=1/100  Signal level=1/100  Noise level=0/100
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
