In this lesson, you will connect the board to the Internet using the integrated Wi-Fi module.
In this section you will:
Check if your Toradex SoM has a
Wi-Fi module. See it highlighted in the example below and try to identify the same device on your SoM:
If it doesn't, you can proceed to the
Access the Linux terminal as explained in the previous lesson Linux Terminal and Basic Usage - Linux.
Scan for available Wi-Fi access points by running the command below:
# nmcli device wifi list
Wait for the output message:
IN-USE SSID MODE CHAN RATE SIGNAL BARS SECURITY NET_2GBA39CF Infra 1 195 Mbit/s 100 **** WPA1 WPA2 TORADEX_BRASIL Infra 5 270 Mbit/s 100 **** WPA1 WPA2 TORADEX_BRASIL_5GHZ Infra 36 405 Mbit/s 79 *** WPA1 WPA2 DIRECT-knM288x Series Infra 11 54 Mbit/s 77 *** WPA2 LusiasWiFi Infra 1 195 Mbit/s 75 *** WPA1 WPA2 #NET-CLARO-WIFI Infra 1 195 Mbit/s 75 *** --
Connect to a Wi-Fi network by locating the
SSID of the network to which you want to connect and running the following command:
# nmcli -a device wifi connect <WIFI_NAME>
Note: In the command above, you will replace
<WIFI_NAME> with the name you found in the
Authenticate with the Wi-Fi network:
Upon running the command in Step 3, you will be prompted for a password. Below, you will see the command to connect to SSID
TORADEX_BRASIL, followed by the password request:
# nmcli -a device wifi connect TORADEX_BRASIL Password: *********
After typing the password and pressing enter/return, the connection status message should appear:
Device 'wlp1s0' successfully activated with 'e17b1631-06c3-4720-a27d-6220775f8c6b'.
Note: The next time you reboot the system, the network will connect automatically as long as the access point is within range.
Verify and view the details of the Wi-Fi connection you made with the following command:
You should see a section that starts with wlp1s0, similar to the one below:
wlp1s0: connected to TORADEX_BRASIL "Marvell Wi-Fi" wifi (mwifiex_pcie), xx:xx:xx:xx:xx:xx, hw, mtu 1500 inet4 10.0.0.42/24
The IP Address of your Wi-Fi adapter is on the line starting with "inet4".
Ping a website using the
Wi-Fi interface to verify that you have Internet access:
# ping -I <interface> -c 4 google.com
PING google.com (220.127.116.11): 56 data bytes 64 bytes from 18.104.22.168: seq=0 ttl=52 time=16.131 ms 64 bytes from 22.214.171.124: seq=1 ttl=52 time=17.839 ms 64 bytes from 126.96.36.199: seq=2 ttl=52 time=17.629 ms 64 bytes from 188.8.131.52: seq=3 ttl=52 time=16.691 ms --- google.com ping statistics --- 4 packets transmitted, 4 packets received, 0% packet loss round-trip min/avg/max = 16.131/17.072/17.839 ms
Killing a connection command can make future commands fail. A reboot usually fixes this.
