Update Wireless Info on Raspberry Pi

Hi everyone,

Just a quick post on how to configure wireless info on a raspberry pi. To start with, open the config file:

sudo nano /etc/wpa_supplicant/wpa_supplicant.conf

You can then add any number of connections to the file with varying priorities:

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

network={
        ssid="Mobile Network"
        psk="YOUR_PASSWORD"
        key_mgmt=WPA-PSK
        priority=2
}

network={
        ssid="Home Network"
        psk="YOUR_PASSWORD"
        key_mgmt=WPA-PSK
        priority=10
}

Then save the file. Your raspberry pi will now connect to the network with the highest priority first (home network), when that’s not available it will use the network with the lower priority (mobile network).

The official doco is actually pretty good for this use case if you need more info: https://www.raspberrypi.org/documentation/configuration/wireless/wireless-cli.md

Start a Script on Startup – Raspberry Pi

Hey guys,

Just thought I’d leave a couple of links to some guides I came across for setting up boot scripts on a raspberry pi.

Quick guide on how to get them running: http://www.instructables.com/id/Raspberry-Pi-Launch-Python-script-on-startup/

How to delay the boot process until the network is available: https://raspberrypi.stackexchange.com/a/45774
