Separate the stereo pair of Fives and unplug them both from power for a couple of minutes and reboot your router. Then swap the two speakers (left speaker is now the right speaker, right speaker is now the left speaker) and plug them back in and create a stereo pair.

NOTE: The Fives aren’t designed to be used as your primary TV speakers. If you connect the Fives to the TV via line-in, you may experience lip sync issues.
