No Power – My Coverage Unit won’t turn on!
When your system does not power up, or has a red power indicator, one of the following things could be happening. You might have a power adaptor failure, a hardware failure, or the system may need a simple restart.
Try this… Both the Coverage Unit and Network 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 Coverage Unit try another outlet, or another lamp/appliance in the same outlet. If you continue to have problems with the 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.
Numeric display keep cycling/rotating.
When your Coverage Unit displays a rotating “0” zero your system is still preforming startup procedures. This process usually takes less than 20 minutes. If it takes longer than 45 minutes, please restart both units.
Low Number on my Coverage Unit (0-6)
When you have a display of 0, 1, 2, 3, 4, 5, or 6 your Cel-Fi DUO system has established a connection but is not working to the fullest ability. Try this… move your units further apart. If you have a particular spot in your home that you want coverage more than others try installing your Cel-Fi system in reverse. Put your Coverage Unit where you need coverage the most then place your Network Unit at the furthest location where you can get at least 1 bar of service.
If you cannot get your systems further apart, and you have the coverage you need, a higher number is not always possible or necessary.
When you have a solid “0” zero display you may also see a flashing green power indicator. This display indicates that your Network Unit and Coverage Unit are “Too Close” together. Try moving the units further apart, starting with the Coverage Unit.
Small Coverage Bubble – I only have signal within a few feet of the Coverage Unit!
Changes to your Cel-Fi placement can be made to improve your 4G LTE/XLTE coverage.
The more bars shown on the Network Unit the better. Try moving the Network Unit to an area that has better 4G LTE/XLTE coverage. If the home/office has more than 1 floor upstairs is usually better than downstairs. Putting the Network Unit near a window or higher on a shelf often helps as well.
The numeric value on the display of the Coverage Unit is an indication of the area covered. A higher number means a larger area is covered. To increase the coverage area move the Coverage Unit farther away from the Network Unit. The less obstacles in their direct line of sight the further apart you can get them. The higher the Coverage Unit number, the better the coverage.
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/XLTE signal due to intermittent network outages, your phone may not support LTE/XLTE, or your phone may not be compatible with the frequency being boosted by the Cel-Fi DUO+. You will need to check the display on your Network Unit.
Frequent or Intermitten “Too Far” message
Intermittent rotating/too far issues. While the number 9 is the largest distance between your Coverage Unit and your Network Unit you can have the systems slightly too far apart. This may cause you to experience intermittent interference which can cause the connection to break. Frequent or intermittent issues can be related to heavy WiFi saturation in your home/office, or obstacles that move between the two units line of sight. Make sure that each unit is as far as possible from any access points or other WiFi enabled devices. An example of a wireless device could be, but is not limited to, a wireless home phone, laptop computer, or wireless router.
Flashing E message.
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.
E2 Coverage 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 Coverage Unit.Try this….Reset your Coverage Unit. Simply unplug your Coverage Unit for a few seconds and plug back in.
E3 Your Coverage Unit is overheating. Try this… ensure that your Coverage Unit vents are clear of any blockage, and that the location of the unit allows free flow of air. Once your Coverage Unit has cooled down it will operate as normal.
E4 Your Network Unit is overheating. Try this… ensure that your Network Unit vents are clear of any blockage, and that the location of the unit allows free flow of air. If you have your Network Unit in an attic space you may need to relocate the device to ensure that the system does not continue to overheat. Once your Network Unit has cooled down it will operate as normal.
E7 The system has been disabled by the mobile network carrier. Contact your point of sale.
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. Note: When you have an E8 your system will still offer you indoor cellular coverage.
Too close, you may also see a solid zero on your Coverage Unit. Your Coverage Unit is “Too Close” to your Network Unit. Try this…moving the units further apart, starting with the Coverage Unit.
Too far, you may also see a rotating/cycling zero with red arrows on your Coverage Unit. Your Coverage Unit is “Too Far” from your Network Unit. Try moving the units slightly (5-10 feet) closer together, starting with the Coverage Unit.
Intermittent “Too Far” message? Frequent or intermittent issues can be related to heavy WiFi saturation in your home/office. Make sure that each unit is as far as possible from any access points or other WiFi enabled devices.
