How to improve CEL-FI DUO+ coverage?
If you are experiencing a low Coverage Unit number or Network Unit input signal, the Network Unit and Coverage Unit might be too close together, or the Network Unit signal level might be low. To resolve this, move the Coverage Unit away from the Network Unit to get a higher coverage number. Consider placing the Coverage Unit on the opposite end of your home.
What to do if CEL-FI Extender Network Unit has no lights and a red power indicator?
If there are no lights on the Network Unit display and the power indicator is red, it indicates that the device is not receiving power. First, ensure the unit is properly plugged in and that there is power at the outlet. If both are confirmed, try exchanging the power supplies with the Coverage Unit to check if the power supply is defective.
What to do if CEL-FI Extender Coverage Unit has no lights, red power indicator, and cycling display?
If there are no lights on the Coverage Unit display, the Coverage Unit power indicator is red and the seven-segment display is cycling for more than a minute, it means the device is not powered. Here are some steps to troubleshoot: 1. Check if the unit is plugged in. 2. Verify if there is power at the outlet. 3. Try swapping the power supplies with the Network Unit to see if the power supply is faulty. Also: 1. Wait for the display to stop cycling; this may take several minutes. 2. Ensure other electronic devices like Wi-Fi routers, home phones, and computers are at least 1 meter away from both units. Increase the distance between the Coverage Unit and the Network Unit.
What to do if CEL-FI Extender Network Unit has no 4G LTE signal?
To troubleshoot a CEL-FI Extender Network Unit with no 4G LTE signal, try moving the Network Unit to another room or area where you have coverage. Also, ensure that the vents on the unit are not blocked and move the unit to a cooler area. The system should start working normally once it cools down.
