Let's say my rPi is functioning properly and has a working Ethernet connection; it has a local IP and I can connect to it.
I disconnect the rPi's Ethernet cable because I need it for another device and then when I put it back into the rPi, it doesn't receive a local IP and in order to do so, I've to restart the rPi with the Ethernet cable already attached to it.
My question is, is there a configuration setting somewhere on Raspbian to make the rPi auto-connect with the router once the Ethernet cable is attached? I did some research but couldn't find anything related.
