Since the firewall is mostly the issue when it comes to connection problems, you must open certain firewall ports for the connection to be enabled. Here are all the ports you need to open (NOTE: These ports have to be opened on the Windows firewall, not the router's)Port numbers are on the left hand side. You have to manually open these ports. ***INSTRUCTIONS ON HOW TO OPEN THESE PORTS ARE LISTED BELOW THE PORT NUMBERS THAT ARE SHOWN BELOW***
2869 UPnP Framework TCP 1900 UPnP Framework UDP 10284 Windows Media Connect UDP 10283 Windows Media Connect UDP 10282 Windows Media Connect UDP 10281 Windows Media Connect UDP 10280 Windows Media Connect UDP 10243 Windows Media Connect TCP
To manually open a port, follow these steps:
1. Click "Start", and then click "My Network Places".
2. Under "Network Tasks", click "View Network Connections." (Or, right-click "My Network Places" on the desktop, and then click "Properties".)
3. Right-click the connection that you use for the Internet, and then click "Properties".
4. Click the "Advanced" tab, and then click "Settings".
***Note If the Settings button is unavailable, ICF is not enabled on this connection, and you do not have to open any ports (because they are all already open).***
5. Click "Add" to open a new port.
6. In the "Description" box, type a friendly name. For example, type File Sharing : Port 445.
7. In the Name or IP address of the computer hosting this service on your network box, type 127.0.0.1.
***Note You can specify the IP address of an internal computer. But you typically will use 127.0.0.1.***
8. In the "External port" and "Internal port" boxes, type the port number. Generally, this number is the same.
9. Click either TCP or UDP, and then click OK.
10. Repeat steps 1 through 9 for each port that you want to open.
