Q: Why can't I see my compatible PC in my device in the home
network?
A: If you are using a firewall application in your compatible
PC, check that it allows home media server to use the
external connection (you can add Home media server to
the firewall application's exceptions list). Check from the
firewall settings that the firewall application allows traffic
to the following ports: 1900, 49152, 49153, and 49154.
Some WLAN access point devices have a built-in firewall.
In such cases, check that the firewall in the access point
device does not block traffic to the following ports: 1900,
49152, 49153, and 49154.
Check that the WLAN settings are the same in your device
and compatible PC.
