IPv4 Group Address – 224.0.0.251
The addresses used by the mDNS protocol are link-local multicast addresses and thus are only forwarded on the local L2 domain. Routers cannot use multicast routing to redirect the traffic because the time to live (TTL) is set to one, and link-local multicast is meant to stay local by design. If you are using a newer higher end router with wireless N and AC, some of these offer different network SSID (human readable network identifiers, i.e. HomeWifi, ATTWireless, etc) and also have a feature to separate the two on different but routable subnets. Unless you can permit these to traverse it, make sure you are on the same SSID and subnet for both. I speculate this may be your cause. If not, open a case with your router/modem combo provider (which may be your ISP).
