With any modem or SmartNID, a quick restart can often fix many connection and wireless issues. So this is one of the first things to try if you're having trouble with your Quantum Fiber internet. You can restart manually or through the app.
NOTE: If you have a wall-mounted C5500XK or C6500XK SmartNID, please be careful when restarting. Do not unplug the green wires on the bottom of the device. These are part of the fiber connection and should not be disconnected.
You can restart your modem remotely through the Quantum Fiber app.
To restart your modem manually, follow these steps:
You'll know you can get back online once the light(s) on the front of the modem turn green.
The WiFi connection on your smartphone (and other devices) will be interrupted when the modem shuts down. Once the network is back up, your WiFi network will come back online and your devices will connect automatically if they are set to remember the network settings. Or you may need to reconnect some of your devices manually.
You may want to try a full modem reset, which returns the modem to its factory default settings. If you have a C5500XK or C6500XK SmartNID, contact us for tech support before attempting a reset.
