====== Edge2 Wi-Fi AP Mode ======

This documentation will introduce how to setup Wi-Fi working on AP mode.

===== Setup Wlan0 as a Hotspot =====

==== 2.4 GHz Frequency ====

For example, the following commands will create AP configuration named ''Hostspot'' on interface ''wlan0'', 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 wlan0 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.addresses 192.168.2.1/24
sudo nmcli con modify Hostspot ipv4.gateway 192.168.2.1
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 ''wlan0'', 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 wlan0 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.addresses 192.168.2.1/24
sudo nmcli con modify Hostspot ipv4.gateway 192.168.2.1
sudo nmcli con modify Hostspot ipv4.method shared
sudo nmcli con up Hostspot
```

Use ''ifconfig'' to check if everything has been setup correctly:

```shell
$ ifconfig
wlan0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.2.1  netmask 255.255.255.0  broadcast 192.168.2.255
        inet6 fe80::f0c0:48fd:6d47:6a4b  prefixlen 64  scopeid 0x20<link>
        ether 70:f7:54:e2:90:89  txqueuelen 1000  (Ethernet)
        RX packets 0  bytes 0 (0.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 30  bytes 4448 (4.4 KB)
        TX errors 0  dropped 2 overruns 0  carrier 0  collisions 0
```

===== Verify =====

You connect to AP ''khadas_ap_2.4G'' or ''khadas_ap_5G'' with password ''12345678''.
