# /etc/hostapd/hostapd-WiFi6.conf
# Documentation: https://w1.fi/cgit/hostap/plain/hostapd/hostapd.conf
# 2024-10-19
# Purpose: hostapd.conf example for WiFi 6 configuration fot USB WiFi adapters using the mt7921au chip.
# Status: rc8, please test and report.
# Note: This hostapd.conf file is for WiFi 6 using band 2 (5 GHz).
# Note: If you want to use WiFi on band 1, 2.4 GHz, there are notes that you need to follow.

# Information:
# - tested on RasPi4B with 64 bit RasPiOS
# - see [Main Menu](https://github.com/morrownr/USB-WiFi) for...
#   -- make sure mt7921 firmware files are installed/updated

#   -- you need hostap 2.10 or later for WiFi 6 support: $ hostapd -v
