beaglebone black wireless wifi setup

From FAQ for BBB boards.
https://github.com/beagleboard/beaglebone-blue/wiki/Frequently-Asked-Questions-(FAQ)

Using Beaglebone blue board instructions for setting up wifi.

Connect with cloud 9 if wished, or connect with ssh to 192.168.7.2, debian, temppwd (if not changed)

Use following from git FAQ to connect at root prompt using connman

connmanctl
connmanctl> tether wifi off (not really necessary on latest images)
connmanctl> enable wifi (not really necessary)
connmanctl> scan wifi
connmanctl> services(at this point you should see your network appear along with other stuff, in my case it was "AR Crystal wifi_f45eab2f1ee1_6372797774616c_managed_psk")
connmanctl> agent on
connmanctl> connect wifi_f45eab2f1ee1_6372797774616c_managed_psk
connmanctl> quit

FAQ copy is missing a newline, and the agent on step isn't apparent.

The beaglbone black wireless has an accesspoint in control of the wifi, and active..

The connect via 192.168.7.2 connects by the USB network connection.

This is the process to connect to the board via the access point.  This will complicate work if there isn't another NIC on the connecting computer, since there will be no internet present from the BBB once connected.

What is the name of the access point SSID and password default on BeagleBone Blue?

SSID: BeagleBone-XXXX where XXXX is based upon the board's assigned unique hardware address
Password: BeagleBone

I've connected to BeagleBone Blue's access point. How do I get logged into the board?

Browse to http://192.168.8.1:3000 to open the Cloud9 IDE and get access to the Linux command prompt.
If you've connected via USB instead, the address will be either http://192.168.6.2:3000 or http://192.168.7.2:3000, depending on the USB networking drivers provided by your operating system.

raspberry pi raspbian wifi setup

Here is a thread about setting the wifi up manually.

wicd-curses curses wifi manager

A few locations discuss headless setup of the raspberry pi for bringing up such as the rpi zero W which can be made to boot up completely disconnected, due to the presence of wifi on the board.

However it would be nice to be able to add an additional Wifi net to connect to for such as when one wants to run the board on additional networks.

My use case is to have a pocket board which runs Linux and can tether if needed to a cell phone wifi for network access.

https://raspberrypi.stackexchange.com/questions/11631/how-to-setup-multiple-wifi-networks

sudo apt-get install wicd-curses

will install a curses utility to manipulate the wifi connections.

armbian wifi, xrdp install

1. Ubuntu-desktop (already installed, but we did sudo apt-get install and found out)
2. TightVNCServer
3. XRDP (with, of course vnc4server installed with the package)

https://docs.ubuntu.com/core/en/stacks/network/network-manager/docs/configure-wifi-connections

https://people.freedesktop.org/~lkundrak/nm-docs/nmcli-examples.html

First, determine the name of the WiFi interface:

$ nmcli d
DEVICE             TYPE      STATE         CONNECTION
...
wlan0              wifi      disconnected     --

Make sure the WiFi radio is on (which is its default state):

$ nmcli r wifi on

Then, list the available WiFi networks:

$ nmcli d wifi list
*  SSID           MODE   CHAN  RATE       SIGNAL  BARS  SECURITY
   ...
   my_wifi      Infra  5     54 Mbit/s  89      ▂▄▆█  WPA2

As an example, to connect to the access point 'my_wifi', you would use the following command:

$ nmcli d wifi connect my_wifi password <password>

<password> is the password for the connection which needs to have 8-63 characters or 64 hexadecimal characters to specify a full 256-bit key.

Raspberry pi zero headless setup

5/21/2019, another setup for headless.  Includes how to do multiple WIFI ssids

Note:  at end of this, remember to change power save setting

If you are using the GUI (Raspian full download) and want to connect your RPi Zero to a keyboard and monitor there are probably easier ways to do this. These notes are for people that want to use a headless (no monitor and GUI) setup ready to connect to your RPi after first boot via SSH from another terminal.

Download Raspbian Lite

wget -O raspbian-lite-latest.zip https://downloads.raspberrypi.org/raspbian_lite_latest
Download link: https://www.raspberrypi.org/downloads/raspbian/

Write Image to SD Card

dd bs=4M if=2017-08-16-raspbian-stretch-lite.img of=/dev/sdb
After this step there should be 2 additional mounts (if not mount the 2 SD card partitions manually).

Set up network interfaces

Create a new config file for the wireless interface.
cd etc/network/interfaces.d/
vim wlan0.conf
Add the following to the new file (if you want to use DHCP – change to static if you want to fix the IP):
auto wlan0
allow-hotplug wlan0
iface wlan0 inet dhcp
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

Set up connection details for local wireless network

vim etc/wpa_supplicant/wpa_supplicant.conf
Check the file and ensure the network settings are as per the Wireless Network you are connecting to.

country=AU
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
network={
ssid="SSID"
psk=HASHED_PSK_VALUE
}
 

country=US
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1

network={
    ssid="your_real_wifi_ssid"
    scan_ssid=1
    psk="your_real_password"
    key_mgmt=WPA-PSK
}

You could use the clear-text PSK passphrase but I prefer not to do that in configuration files. Create a PSK hash using ‘wpa_passphrase‘ this older article
There could be other config values you might need depending on the network you are connecting to. More info: https://linux.die.net/man/5/wpa_supplicant.conf.

Ensure there are DNS Servers configured

sudo vim etc/resolv.conf
Add the following to the new file (or your own nameservers):
# Google's public DNS servers
nameserver 8.8.8.8
nameserver 8.8.4.4

Enable SSH Access

Create an ssh empty file in the mounted boot partition. This is necessary to enable SSH access as SSH is by default disabled on more recent versions of Raspbian.
cd boot/
sudo touch ssh

Boot RPi

Boot the Rpi by powering up and after ~30secs you should be able to connect to the IP assigned. Check your router or ise ‘nmap’ or similar to check the assigned IP:
sudo nmap -p22 -sV 10.1.1.0/24
Default login details are
UID: pi
PWD: rasbperry
My normal further setup steps for RPi 3 are here.
EDIT [2017-08-21]: One of the things necessary on later RPi’s is to turn off power saving mode on the WLAN interface.
sudo iw dev wlan0 set power_save off
