# /etc/hostapd/hostapd-rtl8852cu.conf
# Documentation: https://w1.fi/cgit/hostap/plain/hostapd/hostapd.conf
# 2025-01-19
# Purpose: example hostapd.conf for rtl8852/32cu based USB WiFi adapters.
# Default: WiFi 6 on band 2 (5 GHz), 80 MHz channel width and WPA2.
# Tested with the following Linux vendor driver:
# https://github.com/morrownr/rtl8852cu-20240510
# AP mode requires the following module parameters
# options 8852cu rtw_he_enable=2 rtw_vht_enable=2
# If USB3 mode is desired, also add: rtw_switch_usb_mode=1
# see 8852cu.conf for documentation about the above settings.
# Requirements for band 4 (6 GHz) operation:
# - WPA3 required (see Security section)
# - SAE key management required for WPA3
# wpa_key_mgmt=SAE
# - Management Frame Protection required for WPA3 (see Security section)
# ieee80211w=2
# - WME/WMM required
# wme_enabled=1
# wmm_enabled=1
# - Operating Class required
# op_class=<see Operating Class section>
# Information:
# - tested on RasPi4B with 64 bit RasPiOS
# - you need hostap 2.10 or later for WiFi 6/6e support: $ hostapd -v
# - testing shows significantly reduced range for 6 GHz vs 5 GHz
# - testing shows throughput can be less for 6 GHz vs 5 GHz
# - suggested improvements to this document are welcome
