hello all,
I connected an ethernet shield to pc using RJ45 but the problem  is that it still unidentified network in the ethernet icon and I did the diagnosis it keep showing  "Ethernet doesn't have a valid ip configuration"
please i need the answer the sooner because I need the use of ethernet shield in my Final year project


The Arduino is not providing IP leases to your PC as a router would do. If you don't know how to configure your PC to have a fixed IP address on that interface, connect both, the PC and the Arduino, to a router so they get their IP configuration from it.

I would recommend using static ip settings to get rid of this error.
