Resolving Fluxion Stall When Creating a 5 GHz AP

1. Configure the kernel regulatory domain

Wi?Fi channels are regulated differently across countries and regions. Some 5 GHz channels are reserved for radar detection. If a router operates on a radar?reserved channel, you may not be able to perform packet injection, deauthentication, or create a cloned AP on that channel. Modify the kernel regulatory domain country code according to the Wi?Fi channel compliance table so the wireless adapter uses usable frequency ranges and supports injection, deauthentication, and AP creation.

Example Wi?Fi channel compliance table: https://www.docin.com/p-2253061296.html

Edit the startup configuration file so the country code is set at boot.

# Edit configuration so that, at each boot, the wireless adapter's operating frequency country code is set to CN (China). # PA (Panama) is often recommended to avoid radar channels and allow deauthentication on 5 GHz. ╰─ vim /etc/rc.local #!/bin/bash # THIS FILE IS ADDED FOR COMPATIBILITY PURPOSES ## It is highly advisable to create own systemd services or udev rules # to run scripts during boot instead of using this file. ## In contrast to previous versions due to parallel execution during boot # this script will NOT be run after all other services. ## Please note that you must run 'chmod +x /etc/rc.d/rc.local' to ensure # that this script will be executed during boot. # set wlan frequency country code to PA/CN iw reg set PA exit 0 # Add execute permission ╰─ chmod +x /etc/rc.local

Apply the configuration.

# Restart the service ╰─ systemctl restart rc-local.service ╰─ systemctl status rc-local.service # Or reboot the machine ╰─ reboot

After this change, the 8812au adapter should be able to deauthenticate 5 GHz signals successfully.

2. Configure Fluxion to support 5 GHz AP creation

Edit the Fluxion AP script so it supports creating APs on the 5 GHz band.

# Edit ap script file ╰─ cat Desktop/fluxion-fix-for-5Ghz/lib/ap/hostapd.sh function ap_service_prep() { if [ ${#@} -lt 5 ]; then return 1; fi APServiceInterface=$1 APServiceInterfaceAddress=$2 APServiceSSID=$3 APServiceMAC=$4 APServiceChannel=$5 ap_service_stop # Prepare the hostapd config file. country_code="$(iw reg get | awk 'FNR == 2 {print $2}' | cut -f 1 -d ":" 2> /dev/null)" [[ ! ${country_code} =~ ^[A-Z]{2}$ ]] && country_code="00" rm -rf "$APServiceConfigDirectory/$APServiceMAC-hostapd.conf" > /dev/null 2>&1 echo "interface=$APServiceInterfacedriver=nl80211ssid=$APServiceSSIDchannel=$APServiceChannel" >> "$APServiceConfigDirectory/$APServiceMAC-hostapd.conf" if [[ ${APServiceChannel} -gt 14 ]];then { echo -e "hw_mode=a" } >> "$APServiceConfigDirectory/$APServiceMAC-hostapd.conf" else { echo -e "hw_mode=g" } >> "$APServiceConfigDirectory/$APServiceMAC-hostapd.conf" fi if [[ "${country_code}" != "00" ]];then { echo -e "country_code=${country_code}" } >> "$APServiceConfigDirectory/$APServiceMAC-hostapd.conf" fi
