Obtain Pi MAC Address
The MAC (Media Access Control) address is the ID that identifies your Pi and is required when you register your device on the UALR IOT WiFi network. Press ctrl-alt-t to bring up the command line terminal and type the following code, which is a shortcut for ifconfig
ip a
The above command gives all ip address associated with all network interfaces, and you should see two, the ethernet (eth0) and the WiFi (wlan0), and you need the MAC address associated with wlan0
(be sure to get the MAC address for the wlan0 and not eth0
Register MAC address
Either Google "UALR IOT WiFi" or go directly to the UALR Information Technology Services Wireless network page
https://ualr.edu/itservices/applications/v/wireless/
Scroll down the page until you see the image on the left of figure \(\PageIndex{4}\) and choose UALR-IoT (you would use UALR-WiFi to register your laptop or smartphone)
Go to the bottom of the page and click "Add new device"
Obtain IP address
Now that your PI is registered and on the network you can obtain it's IP address by clicking on the device (left part of figure \(\PageIndex{5}\)).
NOTE, UALR has dynamic and not static IP addresses. This means if you shut off your Pi and reboot it, the IP may change. If that happens, you have three basic options to obtain your IP address:
- Run your Pi in desktop mode (with monitor,keyboard and mouse) and type <ip a> in the command line.
- Login to your UALR IOT network panel and look up the IP address for any device on the IOT network.
- Run a script when your Pi boots to email its IP address to your email account whenever the Pi boots.
