UPnP is a networking protocol for home networks. When you install BRIO, you have a streaming music server (your PC) and a client device - a web browser on another PC or a BRIO mobile app on an iOS or Android phone. UPnP networking on your home router permits the remote client device to connect to your PC. The BRIO server is then able to stream the music stored on your PC to the remote client device.
When the client device is in a remote location (i.e., outside of your home network), it relies on the UPnP networking protocol on your home network router to reach the BRIO server. In many routers, the UPnP protocol function is not enabled by default. The UPnP setting then needs to be manually enabled (via the router admin interface) for UPnP networking to work.
With UPnP, BRIO streams your music to the remote client device at native resolution audio at the maximum available bandwidth - the best musical fidelity possible. Otherwise, BRIO relies on an alternative networking method that inherently limits streaming to remote clients at 320 kbps audio quality.
Checking UPnP On Home Router
To find out if the UPnP networking function is enabled on your home router, click on BRIO Settings page and check "Computer -Remote" IP Address. If it displays the same address as "Computer - Local", UPnP on your router has not been enabled.
Enabling UPnP Manually (On Home Router)
If UPnP is not enabled on your home router, you would need to enable it manually.
1. Apple Airport Routers
Users with Apple Airport routers need to set up Network Translation Address (NAT) Port Mapping Protocol (UPnP). Apple's support page describes the steps in this link. The Apple community discussion thread on this subject is here.
2. Other Routers
For other routers, users will need to use the router admin interface and enable the UPnP settings.
The manner in which the UPnP settings are configured varies between different router manufacturers. An illustration of the UPnP setting for a D-Link router is shown below:
Step 1 Open a web browser and type the IP address of the wireless router in the address bar (default is 192.168.0.1 for D-Link). Please check your router manufacturer's documentation to find the IP address, default username and password. Press Enter.
Step 2 The default username is admin (all lowercase) and the default password is blank (nothing). Click OK.
Step 3 Click the Tools tab then click Misc. to the left.
Step 4 Under the UPnP Settings section, select Enabled using the radio buttons to enable UPnP on the wireless router or select Disabled using the radio buttons to disable it.
Step 5 Click Apply and then click Continue to save the new settings. (Router will now reboot with new settings).
