-===== Download ===== +{{page>products:sbc:edge2:applications:wifi-sta-ap-mode&noheader}}
-``` +
-wget https://raw.githubusercontent.com/khadas/fenix/refs/heads/master/archives/filesystem/common/usr/local/bin/khadas_ap.sh +
-sudo chmod 777 khadas_ap.sh +
-sudo mv khadas_ap.sh /usr/local/bin +
-``` +
-We will add it in next version and users could also rebuild the image. +
-===== Overview ===== +
-This guide explains how to configure dual Wi-Fi mode using the provided script (v1.0), enabling simultaneous operation in: +
- +
-STA+AP Mode: ''wlan0'' as STA (connects to existing Wi-Fi) + ''wlan1'' as AP (creates hotspot) +
- +
-ETH+AP Mode: ''eth0'' as Ethernet uplink + ''wlan1'' as AP (//Note: Not available on Edge-2L devices//) +
- +
-===== Prerequisites ===== +
- +
-Root privileges required +
- +
-Ensure wireless interfaces are properly identified: +
- +
-STA interface: ''wlan0'' +
- +
-AP interface: ''wlan1'' +
- +
-Ethernet interface: ''eth0'' (not present on Edge-2L) +
- +
-===== Configuration Script Usage ===== +
-Run the script with root privileges: +
- +
-``` +
-sudo khadas_ap.sh +
-``` +
- +
- +
-==== Main Menu Options ==== +
-``` +
-======================================== +
- WiFi Configuration Tool v1.0 +
-======================================== +
-1. STA+AP Mode +
-2. ETH+AP Mode +
-3. Stop All Services +
-4. Exit +
-======================================== +
-Please select an option [1-4]: +
-``` +
-1.STA+AP Mode - Recommended for most devices: creates NAT forwarding between ''wlan0'' (STA) and ''wlan1'' (AP), requires existing Wi-Fi connection on ''wlan0'', hotspot IP: ''192.168.43.1'' (DHCP range: 192.168.43.2-254) +
- +
-2.ETH+AP Mode - For devices with Ethernet port: creates NAT forwarding between ''eth0'' and ''wlan1''//Not functional on Edge-2L devices// (no eth0 interface). Same hotspot IP range as STA+AP mode +
- +
-3.Stop All Services - Terminates AP/DHCP/NAT services +
- +
-4.Exit - Quit the script +
- +
-==== Configuration Steps ==== +
- +
-Select operation mode from menu +
- +
-For AP modes (1 or 2): +
- +
-  * Enter SSID for hotspot +
-  * Set password (WPA2-PSK required) +
-  * Script automatically handles: +
-  * Hostapd configuration +
-  * Dnsmasq DHCP setup +
-  * IP forwarding +
-  * iptables NAT rules +
- +
-===== Verification ===== +
-Check interface status after configuration: +
- +
-``` +
-ifconfig wlan0 && ifconfig wlan1 +
-``` +
-Verify internet connectivity (STA+AP mode): +
- +
-``` +
-ping -I wlan0 google.com +
-``` +
-Test hotspot access: +
- +
-SSID: [Your configured SSID] +
- +
-Password: [Your set password] +
- +
-Client IP range: 192.168.43.2-254 +
- +
-===== Important Notes ===== +
-<WRAP important> +
-Edge-2L Device Limitations: +
- +
-No Ethernet interface (''eth0'') +
- +
-ETH+AP Mode (Option 2) will not function +
- +
-Use STA+AP Mode (Option 1) exclusively +
- +
-</WRAP> +
-===== Technical Details ===== +
- +
-IP Configuration: +
- +
-  * AP Static IP: 192.168.43.1/24 +
-  * DHCP Range: 192.168.43.2-254 +
-  * DNS: Google DNS (8.8.8.8) via port 5353 +
- +
-Security: +
- +
-  * WPA2-PSK encryption +
-  * CCMP/AES cipher mandatory +
- +
-Default channel: 6 +
- +
-Dependencies: +
- +
-  * dnsmasq (DHCP server) +
-  * hostapd (AP configuration) +
-  * iptables (NAT forwarding) +
- +
-===== Troubleshooting ===== +
- +
-AP Not Appearing: +
- +
-Confirm ''wlan1'' interface exists +
- +
-Check for conflicting services: +
- +
-``` +
-ps aux | grep -E 'hostapd|dnsmasq' +
-``` +
-No Internet Access: +
- +
-Verify STA connection: +
- +
-``` +
-iwconfig wlan0 +
-``` +
-Check NAT rules: +
- +
-``` +
-iptables -t nat -L -n -v +
-``` +
-DHCP Failures: +
- +
-Confirm dnsmasq running: +
- +
-``` +
-systemctl status dnsmasq +
-```+
