-# Wi-Fi STA/AP Mode
+====== Wi-Fi STA/AP Mode ======
+===== Introduction =====
+This document mainly introduces the STA+AP mode of Wi-Fi. You'll learn how to open a hotspot while connected to the Internet.
+===== System Configuration =====
+==== Upgrade System ====
+Please make sure you use the latest image, if not please follow [[/products/sbc/common/configurations/upgrade-system|Upgrade The System]] to upgrade your system.
+==== Configuration Instructions ====
+Configure ''wlan0'' to ''STA'' mode, and ''wlan1'' to ''AP'' mode.
+=== Add Wlan1 Interface ===
+```shell
+khadas@Khadas:~$ sudo iw phy phy0 interface add wlan1 type managed
+```
+Use ''ifconfig'' to check if ''wlan1'' has been added successfully:
+```shell
+khadas@Khadas:~$ ifconfig
+wlan0: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500
+        ether 18:93:7f:a9:9d:0e  txqueuelen 1000  (Ethernet)
+        RX packets 0  bytes 0 (0.0 B)
+        RX errors 0  dropped 0  overruns 0  frame 0
+        TX packets 2  bytes 180 (180.0 B)
+        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0
+wlan1: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500
+        ether 1a:93:7f:a9:9d:0e  txqueuelen 1000  (Ethernet)
+        RX packets 0  bytes 0 (0.0 B)
+        RX errors 0  dropped 0  overruns 0  frame 0
+        TX packets 0  bytes 0 (0.0 B)
+        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0
+```
+=== Setup Wlan1 as a Hotspot ===
+Setup ''wlan1'' as a hotspot, and allow automatic connections.
+== 2.4 GHz Frequency ==
+We shall name our hotspot ''khadas_ap'', with password ''12345678''.
+```shell
+sudo nmcli con add type wifi ifname wlan1 con-name Hostspot autoconnect yes ssid khadas_ap
+sudo nmcli con modify Hostspot 802-11-wireless.mode ap 802-11-wireless.band bg ipv4.method shared
+sudo nmcli con modify Hostspot wifi-sec.key-mgmt wpa-psk
+sudo nmcli con modify Hostspot wifi-sec.psk "12345678"
+sudo nmcli con modify Hostspot ipv4.addresses 192.168.2.20/24
+sudo nmcli con modify Hostspot ipv4.gateway 192.168.2.1
+sudo nmcli con up Hostspot
+```
+== 5 GHz Frequency ==
+To setup a 5GHz network, you’ll need to use the channel argument. \\
+We shall name our hotspot ''khadas_ap'', with password ''12345678''.
+```shell
+sudo nmcli con add type wifi ifname wlan1 con-name Hostspot autoconnect yes ssid khadas_ap_5G
+sudo nmcli c modify Hostspot 802-11-wireless.mode ap 802-11-wireless.band a 802-11-wireless.channel 149 802-11-wireless.powersave 2 ipv4.method shared
+sudo nmcli con modify Hostspot wifi-sec.key-mgmt wpa-psk
+sudo nmcli con modify Hostspot wifi-sec.psk "12345678"
+sudo nmcli con modify Hostspot ipv4.addresses 192.168.2.20/24
+sudo nmcli con modify Hostspot ipv4.gateway 192.168.2.1
+sudo nmcli con up Hostspot
+```
+Use ''ifconfig'' to check if everything has been setup correctly:
+```shell
+khadas@Khadas:~$ ifconfig
+wlan0: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500
+        ether 18:93:7f:a9:9d:0e  txqueuelen 1000  (Ethernet)
+        RX packets 0  bytes 0 (0.0 B)
+        RX errors 0  dropped 0  overruns 0  frame 0
+        TX packets 2  bytes 180 (180.0 B)
+        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0
+wlan1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
+        inet 192.168.2.20  netmask 255.255.255.0  broadcast 192.168.2.255
+        inet6 fe80::2069:83c5:2e4c:2614  prefixlen 64  scopeid 0x20<link>
+        ether 1a:93:7f:a9:9d:0e  txqueuelen 1000  (Ethernet)
+        RX packets 0  bytes 0 (0.0 B)
+        RX errors 0  dropped 0  overruns 0  frame 0
+        TX packets 18  bytes 1312 (1.3 KB)
+        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0
+```
+===== Go Online! =====
+Verify that wlan0 has a working internet connection:
+<WRAP info >
+You need to connect Wi-Fi first.
+</WRAP>
+```shell
+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.

+Verify that ''wlan1'' can be used as a hotpot:
+  * Name: 2.4G/''khadas_ap'', 5G/''khadas_ap_5G''
+  * Password:''12345678''
