Serviio

Let me start out by saying, yes, I have searched the forum - extensively - tried everything I came across, and I've still had no luck. I have a Samsung bd-d5700 that I just got. I tried it at my old place just once to test it out, and it worked just fine, found Serviio instantly. Then just the other day, I moved into my new apartment, connnected to my roommates router, and it just cannot find Serviio. That being said, can someone help me out?
