Problems connecting with wired Ethernet
The Connected device should work just fine with typical home router configured for DHCP addressing, however, if you are experiencing problems, it could be due to the following:
Your PC firewall may be preventing the device from discovering the server.
Your server software may need to be exited (use the Exit button) and restarted.
Some routers apply MAC filtering to the wired ports if it is enabled.
Your network may have a more advanced topology with multiple segments or bridges. In that case the discovery mechanism will not work unless the multicast and broadcast packets are passed on the by the routers or bridge.
I have also seen a similar problem when I was at a trade show that was blocking the port used for Windows updates. Under the options, advanced setting tab, there is a way to set a custom port. Try setting it to 80 just to see if it can work. If it does, that means that our default port is being blocked by your network. We normally use port 1900 for discovery.
