VIM4 Wi-Fi STA/AP Mode

How to setup the Wi-Fi working on STA+AP mode at the same time.

Configure wlan0 to STA mode, and wlan1 to AP mode.

Setup Wlan1 as a Hotspot

Setup wlan1 as a hotspot.

2.4 GHz Frequency

For example, the following commands will create AP configuration named Hostspot on interface wlan1, with SSID khadas_ap_2.4G, 2.4GHz band, channel 1, WPA2-PSK security, CCMP encryption and passphrase 12345678.

sudo nmcli con add type wifi ifname wlan1 mode ap con-name Hostspot ssid khadas_ap_2.4G
sudo nmcli con modify Hostspot 802-11-wireless.band bg
sudo nmcli con modify Hostspot 802-11-wireless.channel 1
sudo nmcli con modify Hostspot 802-11-wireless-security.key-mgmt wpa-psk
sudo nmcli con modify Hostspot 802-11-wireless-security.proto rsn
sudo nmcli con modify Hostspot 802-11-wireless-security.group ccmp
sudo nmcli con modify Hostspot 802-11-wireless-security.pairwise ccmp
sudo nmcli con modify Hostspot 802-11-wireless-security.psk 12345678
sudo nmcli con modify Hostspot ipv4.method shared
sudo nmcli con up Hostspot

5 GHz Frequency

For example, the following commands will create AP configuration named Hostspot on interface wlan1, with SSID khadas_ap_5G, 5GHz band, channel 149, WPA2-PSK security, CCMP encryption and passphrase 12345678.

sudo nmcli con add type wifi ifname wlan1 mode ap con-name Hostspot ssid khadas_ap_5G
sudo nmcli con modify Hostspot 802-11-wireless.band a
sudo nmcli con modify Hostspot 802-11-wireless.channel 149
sudo nmcli con modify Hostspot 802-11-wireless-security.key-mgmt wpa-psk
sudo nmcli con modify Hostspot 802-11-wireless-security.proto rsn
sudo nmcli con modify Hostspot 802-11-wireless-security.group ccmp
sudo nmcli con modify Hostspot 802-11-wireless-security.pairwise ccmp
sudo nmcli con modify Hostspot 802-11-wireless-security.psk 12345678
sudo nmcli con modify Hostspot ipv4.method shared
sudo nmcli con up Hostspot

Use ifconfig to check if everything has been setup correctly:

Verify that wlan0 has a working internet connection:

You need to connect Wi-Fi first.

khadas@Khadas:~$ sudo ping -I wlan0 www.khadas.com
PING td-balancer-dc11-60-161.wixdns.net (185.230.60.161) from 192.168.124.80 wlan0: 56(84) bytes of data.
