Understand your Wi-Fi
How strong is your Wi-Fi?
Your Wi-Fi signal reading can help explain why a product keeps going offline. Find the number, check what it means and choose your next step.
Make sense of the number
How strong is your signal?
Wi-Fi signal strength is shown in dBm. Values are usually negative: −50 dBm is stronger than −80 dBm. Enter the RSSI reading shown on your product, or try an example below.
The interactive checker needs JavaScript. The signal ranges, menu screenshots and troubleshooting steps remain available.

A fair signal may work, but walls, distance or interference can make it less dependable. If you see dropouts, try improving coverage at the product.
This guide does not measure or connect to your Wi-Fi. The demo only shows how the scale changes.
Find your number
Look for “RSSI”.
On the screen-based product connected to your Wi-Fi, follow this path. Check the product handling the internet connection for your eco-system.
Example menus. Names can vary with product and firmware. Select a screenshot to enlarge it. The example RSSI is −26, which is stronger than the −30 end of the slider.
My product does not have this screen
This menu path applies to screen-based products with Wi-Fi. For zappi GLO, use the Wi-Fi setup and offline guide.
A separate hub connects to your router by Ethernet. harvi uses a radio link. This Wi-Fi RSSI menu is not a signal check for those connections.
Keep this as a reference
Your reading at a glance.
| RSSI reading | Signal | What it suggests |
|---|---|---|
| −50 dBm or stronger | Excellent | A strong received signal. If you are offline, check the wider connection too. |
| −60 to −51 dBm | Good | Usually a good basis for a dependable connection. |
| −70 to −61 dBm | Fair | May work, with less room for obstacles or interference. |
| −90 to −71 dBm | Weak | Dropouts are more likely. Improve coverage at the product. |
| Below −90 dBm | Very weak | The product may struggle to establish or keep a connection. |
General guidance, not a pass/fail test. Signal quality, interference and your router also affect reliability. A reading can change over time.
Give the signal a clearer route
Start with one useful change.
Check RSSI, make one change, then read RSSI again at the same product. This makes the result easier to compare.
Open up the router’s location.
Try an open, raised position with fewer obstructions. Keep it away from large metal objects and other equipment that may interfere.
Bring coverage towards the product.
If distance or walls are the problem, ask your broadband provider about a suitable access point, mesh node or extender.
Compare readings, then watch reliability.
A number closer to zero means a stronger received signal. Also check whether the product stays online over time.
An extender needs a signal to extend.
Place it where it still receives a useful signal from your router, rather than in the area already struggling for coverage.
Illustration only. It does not predict coverage, distance or a dBm improvement for your property.
Did the change help?
Compare before and after.
Use two readings from the same product. The example below moves from −80 dBm to −60 dBm.
This describes received signal power. It does not mean your internet connection is 100 times faster.
Weak before. Good after.
the received signal power. This is not an internet speed increase.
The bars use the −100 to −30 dBm guide scale. They do not show percentages or Wi-Fi speed. Compare readings over time as well as immediately after a change.
Why a small dBm change can matter
dBm expresses received power relative to 1 milliwatt. It uses a logarithmic scale: a rise of 10 dB represents ten times the received signal power; a rise of 20 dB represents one hundred times.
That is a power comparison, not a prediction of connection speed. Interference and background noise still affect how well the signal can be used.
Choose what you see
Still going offline?
The signal is weak or very weak
- Check the reading on the product, not just your phone.
- Try improving router position or coverage towards the product.
- If you use an extender, check that it has a good connection back to the router.
- Read RSSI again, then monitor whether the product remains online.
For coverage and router advice, speak to your broadband provider or network administrator.
The signal is good, but the product is offline
A strong Wi-Fi signal does not prove the whole connection is working. Check whether other products can access the internet and whether your myenergi product shows it is connected to your home network.
Follow the Wi-Fi setup and offline checks. If the app shows warning triangles, use the yellow triangle guide.
The reading keeps changing
Take several readings at different times, especially when a dropout happens. Note the strongest and weakest readings. Walls, distance and changing interference can affect the signal.
A single good reading may miss an intermittent problem. Give your broadband provider the range of readings and when the issue occurs.
I see no RSSI value, or the value is 0
Check the Wi-Fi connection status first. Do not treat a blank or 0 reading as confirmation of an excellent signal.
Confirm you are checking the screen-based product that connects to your home Wi-Fi. Use the connection guide if you need to connect or reconnect it.
My phone has full bars beside the product
Your phone and product may use different antennas or Wi-Fi bands. Their readings are not directly interchangeable. Use the product’s RSSI to assess the Wi-Fi signal it receives.
Router, coverage or broadband
Your broadband provider or network administrator can help with router settings, access point placement and internet dropouts.
Product or app support
Contact myenergi with your product type, serial number, RSSI readings, when it goes offline and the checks you have completed. Do not send your Wi-Fi password.
