Hi all,
I’m a college student, and with that comes internet constraints. We have a packet fence website to register gaming consoles and other various MAC addresses. Anyhow, I got Astroprint on the pi and it works with the local hotspot it creates. But to get it on the internet I need to either hardwire in (ethernet) or connect to the wifi, which all I have to do is register the wlan MAC address with the packet fence. But I’m having trouble finding the MAC address of my Pi. So any help is appreciated, I am a beginner when it comes to the raspberry pi stuff, so I just need a little extra help. Thanks!
I connected mine via cable to start then my router showed the mac address and ip on the network in my router dhcp tables. Then i could web in and config my astroprint wifi settings. But, this is on muy home network. I’m not sure about in your campus setting with the packet fence. 
Connect an HDMI monitor and USB keyboard (or SSH if you know its IP address) then run:
ifconfig
The Mac Address is showns as HWaddr in the output. You want to look at:
- eth0: Wired interface
- wlan0: WiFi interface

Does this require installing NOOBS?
The login and password would be what?
If you haven’t changed them, they’re the same as with any raspberry pi:
username: pi
password: raspberry
You should change this
Ok, never mind I figured it out. I didn’t know that the password doesn’t show up when you type it in. I got the addresses, thank you so much Daniel. Have a good one!
Ok, how do I do that?
type
raspi-config
There are options there to change the password
