-====== Wi-Fi STA/AP Mode ======
+====== 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''.
+```shell
+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''.
+```shell
+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.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:
+```shell

+===== Go Online! =====
+Verify that ''wlan0'' has a working internet connection:
+<WRAP info >
+You need to connect Wi-Fi first.
