I have a to me strange problem and could use some help. I have two raspberry Pi's a model B+ and a model 2. I can hook up the B+ and every thing works just fine but if I connect the model 2 it does not show up in my home network. Like I said the model b+ works fine I can see it from my windows computer and I can add movies and music with no problems. But if I hook up the model 2 I see nothing yet I can connect to the internet using either one. I have them both set to the same IP address and subnet mask on my xfinity router the only difference is the Mac address.I have tried reformatting and reinstalling my Windows computer twice and same thing other pc's like Laptops and I Pads connect fine just not my raspberry Pi model 2.
Any thoughts would be much appreciated
