#: | #: The Wiren Board Wi-Fi is available at a distance of no more than one meter without the antenna.To get a standart Wi-Fi radius of operation, you need to connect antenna to the appropriate connector of the controller. If the controller is in the closet (especially in a metal one) or a separate room, it is better to use a remote antenna. | ||
#: | #: The antenna has standart Wi-Fi connector: RP-SMA (differs from SMA-connector for GSM antennas)[https://en.wikipedia.org/wiki/SMA_connector#Reverse_polarity_SMA RP-SMA] | ||

== | == Setting up Wi-Fi in Linux == | ||
The setting up is usually proceed in a standart way for Linux Debian: via file <code>/etc/network/interfaces</code>. The following are brief instructions for common tasks on Linux Debian, there is a detailed documentation on the Linux site. [https://wiki.debian.org/ru/NetworkConfiguration detailed documentation]. | |||
=== | === Setting up in a hotspot mode === | ||
Access point mode is enabled by default. Operation in the access point mode is provided by the '''[https://wireless.wiki.kernel.org/en/users/documentation/hostapd hostapd]''' daemon. | |||
Configuration process: | |||
# | # Enable access point mode. For this: | ||
#* | #* open file <code>/etc/default/hostapd</code> and uncomment the string(e.g.,remove the # at the beginning of the string)<syntaxhighlight lang="bash">DAEMON_CONF="/etc/hostapd.conf"</syntaxhighlight> | ||
#* | #* edit the <code>/etc/hostapd.conf</code> file like in the example:<syntaxhighlight lang="bash"> | ||

=== | === Setting up in hotspot and client mode simultaneously === | ||
The mode of simultaneous operation of the Wi-Fi module in both the hotspot mode and the client mode is called ''Concurrent Mode'' or ''STA+SoftAP'', and is not supported by all Wi-Fi modules. It also does not work on all versions of the Wiren Board controllers. We've found out that it works out of the box on Wiren Board controllers with Realtek 8723BU chip and Linux kernel 4.1.15. To check that, run the following commands: | |||
<syntaxhighlight lang="bash"> | <syntaxhighlight lang="bash"> | ||
uname -a | uname -a | ||
lsmod | grep 8723bu | lsmod | grep 8723bu | ||
</syntaxhighlight> | </syntaxhighlight> | ||
'' | ''If the conditions are not met, you may still be able to configure Concurrent Mode on your Wiren Board. As a starting point, use the [http://randomstuffidosometimes.blogspot.ru/2016/03/rtl8192cu-and-rtl8188cus-in-station-and.html instructions(rus only)].'' | ||

The method is borrowed from here(ru): [http://alexba.in/blog/2015/01/14/automatically-reconnecting-wifi-on-a-raspberrypi/] | |||
For example, the controller is connected to a router with the ''192.168.0.1'' address via the ''wlan1'' interface. Then: | |||
# | # in <code>/root</code> folder create script <code>wifi_autoconnect.sh</code> as in the example below: <syntaxhighlight lang="bash"> | ||
#!/bin/bash | #!/bin/bash | ||
# | # Substitute the name of the interface | ||
WLANINTERFACE=wlan1 | WLANINTERFACE=wlan1 | ||
# | # Substitute the address of the router or server on the Internet, access to which will be checked | ||
SERVER=192.168.0.1 | SERVER=192.168.0.1 | ||

# Wi-Fi | #Wi-Fi in Wiren Board controllers in hotspot mode is relatively slow. The speed is enough to work with the web interface, but do not use the Wiren Board as a replacement for a standart router. | ||
# | # In very rare cases, the Wi-Fi adapter on the Wiren Board controllers may not be compatible with some other Wi-Fi devices. This is a common problem of Wi-Fi implementations on chipsets from different manufacturers. If you encounter unexplained problems, we recommend to change the encryption settings, channel width, etc. |
