That says that your wired network port is disconnected (no cable) and your wifi is up and has a v4 address assigned.
If that’s not what you expect, you need to explain what you do expect.
The pi 3 has always been connected, via it’s built in wi-fi, to my router, sending data to Flightaware. About 2 weeks ago I received an e-mail from FA, stating a lack of connectivity. Upon doing an IP check with the pi, those are the results I got. I did not change anything, it just stopped. What I want is my pi to connect to the internet (and FA) again, wirelessly. It’s never had a network cable attached to it. All my other home internet connections work fine, just not the pi.
I usually use the command “ifconfig”, to tell me what my IP Address is on each of my interfaces.
It could be that your Ethernet cable came loose at one or both ends, or it could also have gone bad all together. If you previously had connectivity via eth0, and now don’t, I would try replacing your ethernet cable with a new one and if that doesn’t work, try rebooting your pi in addition to see if that brings it up.
If your pi was working with your current image, then I would assume the image is still good, and that you have developed a connection issue with your hardware.
Thanks to all, I unplugged the router for a few minutes, and rebooted the RPi3, and all seems to be working now. I guess the cause will never be known. (The pi does seem to shutdown every 2 weeks or so.). Thanks again.
