The LG R1 bridge unit can be used in either of the two below examples:
1) As a root device (wired to a home router). If your speakers are too far
away to connect to your home router directly then this is a good option.
Its best to install the R1 bridge first in wired mode and then add your speakers.
2) As a non-root device (will work as a wireless bridge). If you already have one
of your speakers connected to your home router and want to expand LG's
proprietary mesh network coverage to a different floor, the R1 bridge will help
in doing this. Make sure the bridge has been installed into a suitable location.
