====== 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.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:

```shell
$ ifconfig

        inet 192.168.31.219  netmask 255.255.254.0  broadcast 192.168.31.255

===== 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.
64 bytes from 185.230.60.161 (185.230.60.161): icmp_seq=1 ttl=240 time=293 ms

```

Verify that ''wlan1'' can be used as a hotpot:
  * Name: 2.4G/''khadas_ap_2.4G'', 5G/''khadas_ap_5G''
  * Password:''12345678''
