No Power – My Network Unit won’t turn on!
When your system does not power up, one of the following things could be happening. You could have a power adaptor failure, a hardware failure, or the system could need a simple restart.
Try this… Both the Network Unit and Coverage Unit have identical power supplies. Try switching the power supplies to see if one of the following issues could be occurring:
If you switch the power supplies and the problem moves from one unit to the other unit then you are experiencing a power supply issue. Please reach out to your point of sale for a replacement power supply.
If, after switching power supplies, you still have no power on your Network Unit try another outlet, or lamp/appliance in the same outlet. If you continue to have problems with the Network Unit please reach out to your point of sale for a system replacement.
If, after switching power supplies both system are functioning properly then your Cel-Fi DUO+ system simply needed a restart. This is not something that should continue, but if it occurs frequently please reach out to your point of sale for support.
No Bars – My Network Unit is not finding the cellular signal!
If your power light is still blinking while you have no bars, your Network Unit is still trying to find the incoming cellular network signal. This can sometimes take more than a few minutes.
Taking longer than 60 minutes? Try this…
Walk around your home/office with your cellular device. Try to find a signal inside your home/office with at least one consistent bar of 4G LTE/XLTE. More bars is always better! Once you have found a signal place your Network Unit in that location.
If you have bars of service on your phone in the location of your Network Unit, and after 60 minutes you are still unable to receive bars of service on your Network Unit try a restart. To restart your Network Unit simply unplug for a moment and then it plug back in. If the restart does not solve the issue please reach out to your point of sale for support.
No bars and a red power indicator? Please refer to the section below about “Red power indicator”.
No LTE/XLTE – My phone still doesn’t have LTE/XLTE!
There are a few reasons why your phone would experience an issue with the LTE/XLTE service.
You may not have LTE/XLTE in your area, your Cel-Fi system may have lost the LTE signal due to intermittent network outages, your phone may not support LTEXLTE/, or your phone may not be compatible with the frequency being boosted by the Cel-Fi DUO+.
A flashing LTE light means that your Cel-Fi DUO+ system is actively searching for the LTE/XLTE signal. The Cel-Fi DUO+ will scan at startup and scan again every 24 hours.
If your LTE/XLTE light is not lit and not flashing, your Cel-Fi DUO+ has lost, or never found an LTE/XLTE signal and has momentarily stopped searching. The Cel-Fi DUO+ will scan at startup and scan again every 24 hours.
Red Power Indicator – My Network Unit has a red power light!
With a flashing red power indicator you may also see an error code displayed on the Coverage Unit (flashing an E then correlating error number).
E1 – Cellular Signal too weak to boost. Try this… Walk around your home/office with your cellular device. Try to find a signal indoors with at least one consistent bar of 4G LTE/XLTE. More bars is always better! Once you have found a usable signal place your Network Unit in this location.
E3 – Coverage Unit is overheating. Insure that your Coverage Unit vents are uncovered and free of debris, and that the location of the unit allows free flow of air. Once the Coverage Unit has cooled to a normal functioning temperature it will restart and operate as normal.
E4 – Network Unit is overheating. Insure that your Network Unit vents are uncovered and free of debris, and that the location of the unit allows free flow of air. Once the Coverage Unit has cooled to a normal functioning temperature it will restart and operate as normal.
With a solid red power indicator you may also see and error code displayed on the Coverage Unit (flashing an E then correlating error number).
E8 – Input signal too strong. An E8 error code is letting you know that your Network Unit is too close to a cellular tower, not necessarily for your operator. This has reduced the output power (coverage bubble) to limit network interference. Try this…Move your Network Unit to another location. You might need to move your system to the other side of your home/office. Note: When you have an E8 your system will still offer you indoor cellular coverage.
E6 – Network Unit hardware error that may be remedied by a reset. Your Coverage Unit may not display a flashing error code. You will likely only see the solid red power indicator on your Network Unit. Try this…reset your Network Unit. Simply unplug your Network Unit for a few seconds and plug it back in.
Flashing Green Power Indicator – My Network Unit’s power light is flashing green!
A flashing green power indicator on your Network Unit means that your system is still performing startup procedures. This could indicate that the Network Unit is trying to find a connection to either the cellular network or your Coverage Unit.
No bars with a flashing power indicator means the system is trying to locate the cellular network. This normally takes less 60 minutes. Make sure that your phone (cellular device) has at least one bar of 4G LTE/ XLTE signal where the Network Unit is located.
If you have bars but the power indicator is flashing this means that your Network Unit has located the cellular network and is now trying to locate your coverage unit. For more information about Coverage Unit issues click here (add link to Coverage Unit Trouble Shooting section).
Flashing Bars – My Network Unit bars are flashing.
With flashing bars on your Network Unit you may also see and error code displayed on the Coverage Unit (flashing an E then correlating error number).
E7 – The system has been disabled by the mobile network operator. Contact your operator for more information.
