If you are still not sure what we are talking about here, I recommend that you take 5 minutes to watch this video. The first third of the book teaches you the basics, but the following chapters include projects you can try on your own. It’s a 30-day challenge where you learn one new thing every day until you become a Raspberry Pi expert. If you’re looking to quickly progress on Raspberry Pi, you can check out my e-book here.

I will also share additional ways for you to find it in different situations. In this tutorial, I’ll show you how to find your MAC address with ifconfig. It’s represented as a 12-digit hexadecimal number (AA:BB:CC:DD:EE:FF). You’ll find the MAC address after the keyword “ether” in the section corresponding to your network interface. The easiest way to find the MAC address on a Raspberry Pi is to use the “ifconfig” command. I will share everything you need to know about finding the MAC address on your Raspberry Pi. Windows), but you might need help finding it on Raspberry Pi. You probably know how to do this on other systems (i.e. The correct node for would be Use this node's alias or add a reasonable one yourself if missing.Īttention: Note that label MAC addresses are assigned relatively randomly by vendors, so label-mac-device should be regularly put into DTS files or DTSIs with few users, so it is not inherited by accident.On some networks, you can configure a MAC address whitelist to only allow authorized devices. If you find the label MAC address here, check your DTS for the corresponding parent node. There may be one, two or no paths giving the correct address. Valid choices are only mac-address or local-mac-address. It will give you a list like the each of the returned paths (if there are any), retrieve the mac-address, e.g.

To check whether there actually is a usable MAC address, check the device tree on your router:įind /proc/device-tree/ -name '*mac-address'Īttention: This will only work if you have already set up MAC addresses correctly based on the information retrieved above. Obviously, this is only valid if the 5 GHz Wifi device tree node actually has been named wifi0.Īttention: Not all interface can be referenced this way. For that purpose, one needs to reference the node with an alias, e.g.

We can refer to the device bearing the label MAC address in DTS.
