update wifi configuration
The procedure was tested on an SBC Lynx with ConfigID=0x0000000C (PCB revision CS214515A), starting from XUELK 1.1.3 binaries.
 
====WiFi (client mode)====
The procedure here described can be used to connect to an Access Point, using the WPA2/PSK security protocolwith network address given by the AP via DHCP. User can also follow [https://wiki.debian.org/WiFi/HowToUse#Command_Line this guide from Debian Wiki] for a generic approach.
As the WiFi driver is not statically linked to the kernel image, it is necessary to load the module first. This operation is done automatically upon boot, as the module is listed in <code>/etc/modules</code>:
</pre>
 To bring Once the WiFi module is loaded, it's time to configure the interface up: first of all we need to fix interface renaming with the following command:
<pre class="board-terminal">
root@arm:~# iw ln -s /devphy#0 Interface wlan0 ifindex 4 wdev 0x1 addr 88:33:14:5e:30:61 type managedroot@arm:~# ip link show wlan04: wlan0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop qlen 1000 link/ether 88:33:14:5e:30:61 brd ff:ff:ff:ff:ff:ffroot@arm:~# ip link set wlan0 up[ 276null /etc/systemd/network/99-default.076847] wlcore: firmware booted (Rev 6.3.10.0.133)[ 276.097912] IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not readyroot@arm:~# ip link show wlan04: wlan0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq qlen 1000 link/ether 88:33:14:5e:30:61 brd ff:ff:ff:ff:ff:ff
</pre>
 The connection will be established with Generate the SSID named PSK from the ESSID and the clear text passphrase using <code>SSID_ZyXEL_WPA2wpa_passphrase</code>tool:
<pre class="board-terminal">

root@arm:~# cat /etc/wpa_supplicant.conf

network={
ssid="SSID_ZyXEL_WPA2"
</pre>
Edit <code>/etc/network/interfaces</code> and change the <code>wlan0</code> configuration as follows, by entering the <code>ssid</code> and <code>psk</code> generated above:
<pre class="board-terminal">
auto wlan0
iface wlan0 inet dhcp
wpa-ssid SSID_ZyXEL_WPA2
wpa-psk
ec41b79ebdf10022908aa10189b0341f095fd62eeb719a67c5c920e0cde28564
</pre>
Start User can now restart <code>wpa_supplicantsystemd</code>networking service with:
<pre class="board-terminal">

</pre>
 Once Now you can check the connection process completed successfullysystem configuration using standard tools (<code>route</code>, <code>ifconfig</code>, <code>iw</code> reports ). E.g. to check the WiFi link status as followsuse:
<pre class="board-terminal">
root@arm:~# iw wlan0 link
dtim period: 1
beacon int: 100
</pre>All of the above configuration are persistent at reboots and automatically started by <code>systemd</code> at boot time.
 
After assigning a (static) IP address to the <code>wlan0</code> interface, it is possible to ping the Access Point:
<pre class="board-terminal">
