When streaming content between your devices, younity uses one of three transfer mechanisms (in order of preference):
- LAN: The Local Area Network. If your devices are on the same local network (e.g. the same WiFi network), younity will transfer data directly between them. The data is transferred without going over the internet. This is the fastest transfer mechanism, so younity always uses it if it is available.
P2P: Peer-To-Peer. If your devices are not on the same LAN, but are reachable via either the UPnP or NAT-PMP protocols, younity will use UPnP and/or NAT-PMP to transfer data between them. The data is transferred over the internet, but does not need to be "relayed" through our servers. This is the next-fastest transfer mechanism -- younity uses it if LAN is not available.
RELAY: If your devices are not on the same LAN, and are not reachable via P2P, younity will "relay" the transfer through our servers. This mechanism is the slowest, so younity uses it only as a last resort if LAN and P2P are unavailable. Please note that relay transfers are private and secure -- we use industry standard SSL for secure connections, we do not archive or examine the data in any way while it is being transferred, and we do not keep a record of the transfer in our systems.
If you find that one or more of your desktop or laptop devices are consistently unavailable over P2P, you may be able to adjust that device's router's settings to enable P2P. Enabling P2P is a good idea if you often use younity away from home or any place where your devices are not on the same LAN. In those cases, P2P should give much better performance than RELAY.
By default, most home network routers (DSL modems, cable modems, and WiFi routers) will have P2P enabled, but many work network routers and some home network routers will not. The instructions for enabling P2P vary from router to router but generally, enabling P2P simply requires you to adjust your router's settings to enable one of the following peer to peer protocols: UPnP (Universal Plug and Play) and NAT-PMP (NAT Port Mapping Protocol).
If you have access to your router's settings, please make sure that either UPnP or NAT-PMP (or both) are enabled. If your router supports both UPnP and NAT-PMP, you may wish to first enable just NAT-PMP, which is the newer protocol, before enabling UPnP.
Once you have enabled UPnP and/or NAT-PMP on your router, just revisit the younity Settings view to see if your device is now available via P2P. If it is still unavailable via P2P, you are welcome to open a support ticket and we will attempt to help you, though please be aware that it might be difficult to diagnose the problem without access to your individual network environment.
Instructions follow for configuring P2P on several popular WiFi routers. Good luck, and let us know if you have any problems or questions.
Thanks for using younity!
