WiFi

The MBa8MP-RAS314 features a WiFi module (LBEE5XV1YM from Murata).
The LBEE5XV1YM is connected to the MBa8MP-RAS314 via PCIe (for WiFi) and UART (for a wireless function). The theoretically achievable maximum data rate of the LBEE5XV1YM is 866 Mbit/s.

This guide describes how to connect to a wireless network from the command line via wpa_supplicant on your MBa8MP-RAS314.
1. First enable the WiFi interface via ip link set dev wlp1s0 up
2. Edit your wpa_supplicant.conf located under /etc/wpa_supplicant.conf and make sure the content is the following:

Make sure you change the SSID and PSK according to your desired wifi network.

ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
update_config=1
 
network={
      key_mgmt=NONE
}
 
network={
        ssid="Your_SSID"
        psk="Your_Password"
}

3. Now, start the wpa_supplicant service. You must specify both the interface and the configuration file.
-B: Runs the process in the background.
-i wlp1s0: Specifies the interface to use.
-c /etc/wpa_supplicant.conf: Specifies the path to the configuration file.

The full command looks like this:
wpa_supplicant -B -i wlp1s0 -c /etc/wpa_supplicant.conf

4. Obtain an IP Address using udhcpc
e.g.: udhcpc -i wlp1s0
5. Finaly verfiy the connection by first checking if the interface is enabled using ip a and pinging google.com afterwards ping google.de
