Raspberry Pis remind me of risograph machines.

Sometimes they work.
Sometimes they don't.
Depends how they're feeling.

I went out to run errands this morning and when I came home both raspypi and piBo were disconnected from my local network. They were connected just fine before I left!

The good news is that I managed to physically connect them to my router and they are showing on the network!

The connection setup is a bit convoluted because I only have one ethernet cable.

I just spent the whole day drawing a diagram of my Pi network.
