What does “Smart Bridge Disconnected” mean?

<p>If you see a red banner at the top of your screen that says <span class="inline-block">“Smart Bridge Disconnected”,</span> it means one of three things:</p>
<ul class="numbered-list">
<li>Your <span class="inline-block">Smart Bridge</span> is currently unplugged from power.</li>
<li>Your <span class="inline-block">Smart Bridge</span> is currently disconnected from your router.</li>
<li>There is another error that caused your Smart Bridge to lose its connection with the internet.</li>
</ul>
<p>If your <span class="inline-block">Smart Bridge</span> is plugged into power and connected to the internet but you still see the error message, unplug it, wait two minutes, and then plug it back in. Once your Smart Bridge is powered back on, the message should disappear.</p>
