See https://forum.beagleboard.org/t/debian-11-x-bullseye-monthly-snapshots/31280#network-1 for current instructions on the Wifi.
wpa_supplicant
Here are details on how to set up Wifi:
Make sure you have registered MAC address of the Wifi-Dongle. (This is different that the MAC address of the Beagle.)
bone$ ip a ... 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000 link/ether c8:a0:30:a6:26:e8 brd ff:ff:ff:ff:ff:ff inet 137.112.38.183/24 brd 137.112.38.255 scope global dynamic eth0 valid_lft 2591768sec preferred_lft 2591768sec ... 7: wlan0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000 link/ether 82:77:16:86:16:94 brd ff:ff:ff:ff:ff:ff inet 137.112.226.51/22 brd 137.112.227.255 scope global dynamic wlan0 valid_lft 3403sec preferred_lft 3403sec inet6 fe80::8077:16ff:fe86:1694/64 scope link valid_lft forever preferred_lft forever
The MAC address for the wifi is 82:77:16:86:16:94
Wifi configuration: (wpa_supplicant)
sudo nano /etc/wpa_supplicant/wpa_supplicant-wlan0.conf
--> ctrl_interface=DIR=/run/wpa_supplicant GROUP=netdev update_config=1 #country=US
network={
ssid="RHIT-OPEN" key_mgmt=NONE
}
and then restart network with:
/etc/init.d/networking restart
Connect to network:
sudo wpa_cli -i wlan0 reconfigure
Ping google:
ping -c2 google.com
Conman
Here's how to set up wifi on the Bone.
bone$ connmanctl Error getting VPN connections: The name net.connman.vpn was not provided by any connmanctl> scan wifi Scan completed for wifi connmanctl> services *AR RHIT-OPEN wifi_987bf3d2e45e_524849542d4f50454e_managed_none BeagleBone-DF34 wifi_987bf3d2e45e_426561676c65426f6e652d44463334_managed_psk eduroam wifi_987bf3d2e45e_656475726f616d_managed_ieee8021x DIRECT-da-HP M132 LaserJet wifi_987bf3d2e45e_4449524543542d64612d4850204d313332204c617365724a6574_managed_psk
Here is a list of all the access points the Bone can see. Let's pick RHIT-OPEN and connect to it.
connmanctl> connect wifi_987bf3d2e45e_524849542d4f50454e_managed_none
If you get a "Not registered" error when trying to connect, run this:
connmanctl> agent on
Fortunately connmanctl has TAB completion, so you don't have to type the whole name, just type a few characters and then hit TAB. Once connected you can configure it so it will stay connected.
connmanctl> config wifi_987bf3d2e45e_524849542d4f50454e_managed_none --autoconnect yes
Then you can quit.
connmanctl> quit
See if you can hit google.
bone$ ping -c2 www.google.com PING www.google.com (216.58.192.164) 56(84) bytes of data. 64 bytes from ord36s02-in-f4.1e100.net (216.58.192.164): icmp_seq=1 ttl=53 time=9.56 ms 64 bytes from ord36s02-in-f4.1e100.net (216.58.192.164): icmp_seq=2 ttl=53 time=14.5 ms --- www.google.com ping statistics --- 2 packets transmitted, 2 received, 0% packet loss, time 1001ms rtt min/avg/max/mdev = 9.563/12.045/14.528/2.484 ms
It looks good.
More Details
Yes can see help in connmanctl.
