That seems "normal" to be stuck at 22 Mbit/s with the rtw8852b on FreeBSD 14.3.

root@minipc:~ # ifconfig wlan0 mode 11ac
ifconfig: SIOCSIFMEDIA (media): Device not configured

I haven't found any way to switch to 802.11ac mode.

root@minipc:~ # ifconfig wlan0 list caps
drivercaps=581c001<STA,SHSLOT,SHPREAMBLE,MONITOR,WPA1,WPA2,WME>
cryptocaps=b<WEP,TKIP,AES_CCM>

No HTCAP (High Throughput) or VHTCAP (Very High Throughput) capabilities are
listed.
Only basic 802.11a/b/g modes are supported - no MIMO (40 MHz), no VHT (80 MHz).

I'm stuck with a stable but limited Wi-Fi throughput of around 22 Mbit/s.

The hardware is capable of much more, but the current driver doesn't seem to
support it.
