Why does Automower® keep stopping? EPOS® wire free signal issues
If your Automower® robotic lawn mower stops in the lawn in an EPOS® wire free installation, the cause is typically a satellite signal issue or a loss of internet connection. This article helps you identify and resolve the issue.
Understanding satellite signals and correction signal
Understanding satellite signals and correction signal
Standard GPS is only accurate to a few metres; not precise enough for Automower® to navigate reliably within your lawn boundaries. To achieve the centimetre-level accuracy it needs, Automower® uses a correction signal alongside satellite data. This signal continuously calculates the mower’s position, reducing a potential error of several metres down to just a few centimetres.
How your mower receives this correction signal depends on your installation:
- If installed via Husqvarna Cloud, the correction signal is delivered over your home Wi-Fi or the mower’s built-in mobile connection (depending on model). A stable internet connection across the entire work area is essential. The mower will not operate if it loses internet connection.
- If installed with a local reference station, the station generates the correction signal locally and sends it directly to the mower, with no internet connection needed.
Temporary signal interruptions due to weather or surroundings are normal. The mower will pause and resume automatically once the signal improves. If the issue persists, it may be due to obstructions blocking the sky view, insufficient Wi-Fi or mobile coverage across your lawn, or incorrect installation.
Troubleshooting internet coverage issues (EPOS® via Husqvarna Cloud)
If your mower stops and the app displays No correction data available, the mower is not receiving the correction signal it needs from the Husqvarna Cloud to navigate accurately.
Step 1 — Try this first: Restart the mower and wait a few minutes to see if the issue resolves automatically.
Step 2 — If the issue persists: The Wi-Fi or mobile signal likely does not cover the entire lawn. Mobile networks are usually reliable across most locations. If you suspect limited mobile coverage in your area, see our article “Does mobile connectivity work everywhere“. Otherwise, check the options for your model below.
Note: Model availability differs between markets.
Automower® NERA 300 series, Automower® Aspire™ R6V, 308V and 312V
Automower® NERA 300 series, Automower® Aspire™ R6V, 308V and 312V
These models use built-in Wi-Fi to receive the correction signal from the Husqvarna Cloud via your home Wi-Fi.
Improve your Wi-Fi coverage
- Make sure that your home Wi-Fi offers a stable connection across the entire area where the mower operates.
- Move the router so the Wi-Fi signal reaches the entire lawn.
- Install a mesh extender to extend your home Wi-Fi coverage.
Add mobile connectivity
- A Husqvarna dealer can install an Automower® Connect Kit to add mobile network connectivity to your mower. Read more about connectivity and the Automower® Connect kit.
- When equipped with an Automower® Connect Kit, your mower will use the mobile network to receive the correction signal, eliminating the need for Wi-Fi coverage across your work area.
Remove the need for internet for navigation
- A local reference station can be installed to remove the need for internet connectivity for navigation entirely. Read more about the reference station option.
- Installation by a Husqvarna dealer is required for Automower® Aspire™ R6V, 308V and 312V.
Exclude the problem area
- Create stay-out zones to exclude areas without internet coverage.
- Install a wire loop around the area with weak coverage using Support by wire (not available for AI vision models, as these models use their AI vision camera for daytime navigation).
Automower® NERA 400 series
Automower® NERA 400 series
These models can receive the correction signal via Wi-Fi or mobile connectivity, and automatically switch to the other if one connection is lost. The options below focus on Wi-Fi connectivity, since mobile connectivity usually provides a reliable connection to the internet in most locations.

How to check internet coverage across your lawn
Methods to test Wi-Fi and mobile network coverage
Methods to test Wi-Fi and mobile network coverage
With your smartphone
- Connect your smartphone to the same Wi-Fi network as the mower. The Wi-Fi symbol on the phone should indicate at least one bar across the whole work area for reliable operation.
- For mowers supporting mobile connectivity, you can test with your smartphone’s mobile signal. The mobile network symbol should indicate at least one bar across the whole work area. Note that the phone’s indication may not be fully reliable since the mower and smartphone may use different mobile technologies. Read more in our article: “Does mobile connectivity work everywhere”.
With the mower’s display
Use appDrive to drive your Automower® throughout your lawn. The mower display should show at least one Wi-Fi or mobile network bar (depending on model) to ensure reliable operation when using EPOS® via the Husqvarna Cloud.
With the Automower® Connect app
Once EPOS® via Husqvarna Cloud is enabled, the app shows the reception quality of the correction data. The cloud icon should show at least one bar for reliable operation.

Installation guidelines
Correct installation is essential for smooth operation
Correct installation is essential for smooth operation
For both EPOS® installation methods, with a local reference station or via the Husqvarna Cloud, proper installation is essential for receiving signals. Access the full step-by-step installation guide for your specific Automower® model.
Charging station placement
- Maintain at least 6 m/20 ft of free space with a clear view of the sky (C) in front of the charging station (A).
- Position the charging station (A) so that the docking point (B) has an unimpeded sky view. The docking point is where the mower stops after leaving the charging station.
Reference station placement guidelines (if using a reference station)
- Full sky view: Ensure a clear view of the sky (minimum 135 degrees).
- Minimum height: Install at a height of at least 2 m/6.5 ft.
- Distance to the lawn mower: Keep the distance less than 100 m/330 ft. Objects in between can reduce this distance.
- Wall installation: You can mount the reference station on a post or wall. If installing on a wall, ensure the top of the reference station is above the wall.
- Interference: Check for metal objects that may interfere with the signal, such as metal fences.
