Arlo Camera Not Working? 7 Proven Fixes That Work

Your Arlo Camera Is Not Working — Here’s How to Fix It

If your Arlo camera has stopped functioning, you’re not alone. This guide provides brand-specific solutions tailored to Arlo’s unique features, including its proprietary RF sync, SmartHub port requirements, and model-specific reset procedures. Whether your camera is offline, unresponsive, or failing to connect, the steps below will help you restore it to full functionality.

Quick Fixes to Try First

Before diving into complex troubleshooting, try these 30-second checks that address the most common causes of Arlo cameras not working:

• Power cycle your camera: Unplug the camera or remove its battery for 30 seconds, then reinsert or reconnect it. This resets the device and may resolve temporary glitches.
• Check the LED indicator: A blinking red LED usually means a low battery, while a solid red light may indicate a connection issue. For battery-powered models, ensure the battery is fully charged.
• Verify app login: Open the Arlo Secure app, ensure you’re logged in with the correct account, and check if the camera is listed as online. If not, try logging out and back in.
• Inspect the power cable: For wired models, ensure the power cable is securely connected to both the camera and the transformer. A loose connection can cause the camera to power off unexpectedly.
• Restart the app: Close the Arlo Secure app completely and reopen it. This can refresh the app’s connection to your camera and resolve temporary software issues.

Step-by-Step Troubleshooting

Check Your Arlo Camera’s Wi-Fi Band Settings

Arlo cameras require a stable 2.4GHz Wi-Fi connection, especially for models like the Arlo Essential 2K and Arlo Essential Indoor. Dual-band or 5GHz networks can cause connectivity issues. In the Arlo Secure app, navigate to Device Health → Wi-Fi Settings and ensure your camera is connected to the 2.4GHz band. If your router uses a single SSID for both bands, you may need to manually create a separate 2.4GHz network for your camera.

Update Your Arlo Firmware

Outdated firmware can cause instability or compatibility issues. To update your camera’s firmware:

1. Open the Arlo Secure app and go to the Device Health section.
2. Tap Firmware Update. If an update is available, follow the on-screen instructions to install it.
3. Ensure your camera is connected to a stable power source during the update process. A failed update may require a factory reset.

For Arlo Pro 6 models, firmware updates can also be initiated through the Settings menu in the app. Always ensure your router is not blocking ports 80, 123, and 443, as these are required for successful updates.

Verify Arlo SmartHub Port Settings

If your Arlo camera is connected to an Arlo SmartHub (VMB5000/VMB4540), ensure your router is not blocking the following ports: 80, 123, and 443. These ports are essential for the SmartHub to communicate with your camera and the Arlo servers. To check your router’s port settings:

1. Log in to your router’s admin panel (usually accessible via a web browser).
2. Navigate to the Firewall or Port Forwarding section.
3. Confirm that ports 80, 123, and 443 are open and not blocked by any firewall rules.

If these ports are blocked, your camera may fail to connect to the SmartHub or the Arlo servers. For Virgin Media Hub 5x users, double-NAT configurations can also interfere with connectivity, so consider contacting your ISP for further assistance.

Re-Pair Your Arlo Camera

If your camera is still not working after updating firmware and checking port settings, try re-pairing it with the Arlo Secure app:

1. Factory reset the camera: For Arlo Essential 2K models, press and hold the Pairing button on the top of the camera for 15-30 seconds until the LED turns solid blue, then blinks amber three times. For Arlo Pro 6 models, press the Sync button for 10 seconds until the LED blinks blue.
2. Open the Arlo Secure app and go to Settings → Add a New Camera.
3. Follow the on-screen instructions to re-pair the camera with your Wi-Fi network and SmartHub (if applicable).

Ensure the camera is within 1-3 metres of the SmartHub during pairing, as Arlo cameras use proprietary RF for initial sync. If the camera is out of range, it may fail to connect properly.

Use the Arlo Wi-Fi Troubleshooting Tool

The Arlo Secure app includes a built-in Wi-Fi Troubleshooting Tool that can automatically diagnose and resolve connectivity issues. To access it:

1. Open the Arlo Secure app and go to Device Health.
2. Tap Wi-Fi Troubleshooting Tool.
3. Follow the prompts to test your Wi-Fi signal strength, identify interference sources, and adjust your camera’s position for optimal connectivity.

This tool can also help you determine if your camera is using the correct Wi-Fi band (2.4GHz) and provide recommendations for improving signal strength.

Advanced Diagnostics and Factory Reset

Diagnose Using the Arlo Signal Strength Meter

Arlo cameras rely on a strong Wi-Fi signal to function properly. If your camera is in a location with poor signal strength, it may become unresponsive or fail to connect. To check signal strength:

1. Open the Arlo Secure app and go to Device Health → Signal Strength.
2. Look for the signal strength indicator. A weak signal (below -70dBm) may cause connectivity issues. For Arlo Essential models, move the camera closer to your router or install a Wi-Fi extender.
3. For Arlo Pro 6 models, ensure the camera is not in a location with high interference from other devices (e.g. microwaves, cordless phones).

When to Contact Arlo Support

If all troubleshooting steps fail, it may be time to contact Arlo’s support team. Before reaching out, ensure you have:

• Taken detailed notes on the issue (e.g. when it started, what steps you’ve tried, and any error messages).
• Captured diagnostic logs from the Arlo Secure app. These can be found in Device Health → Diagnostic Logs.
• Confirmed that your firmware is up to date and your router’s ports are open.

Arlo’s support team can guide you through advanced diagnostics or arrange for a replacement if the issue is hardware-related.

Root Causes and UK-Specific Challenges

Arlo cameras not working can stem from several root causes, including weak Wi-Fi signals, outdated firmware, or incorrect port settings. In the UK, construction materials like solid brick, cavity walls, and foil insulation can severely degrade Wi-Fi signals, especially for 5GHz networks. This can cause Arlo cameras to lose connectivity even if they’re within range of the router. Additionally, ISPs like Virgin Media and EE/Three/Vodafone mobile broadband may use double-NAT or CGNAT configurations, which can prevent remote access to your camera via the app.

For Arlo SmartHub users, ensuring that ports 80, 123, and 443 are open on your router is critical. If these ports are blocked, the SmartHub may fail to communicate with the Arlo servers, resulting in an offline camera. In such cases, contact your ISP or router manufacturer for assistance.

Prevention and Long-Term Care

To prevent future issues with your Arlo camera, follow these best practices:

• Regularly update firmware: Keep your camera’s firmware up to date to ensure compatibility with your router and Arlo’s servers.
• Monitor battery levels: For battery-powered models, charge the battery fully before use and replace it if it degrades over time. Arlo batteries typically last 3-5 years.
• Avoid interference: Place your camera away from other wireless devices that may cause signal interference (e.g. microwaves, cordless phones).

Full disclosure: we built scOS to address exactly this—the frustration of cameras that depend on Wi-Fi to function. scOS uses permanently powered cameras connected via ethernet, eliminating the need for Wi-Fi altogether.

Replacement Decisions and Device Lifespan

If your Arlo camera is no longer working despite troubleshooting, it may be time to consider replacement. Arlo cameras typically last 3-5 years for battery-powered models and 5-8 years for wired models. Signs that replacement is needed include:

• Persistent connectivity issues that cannot be resolved via firmware updates or port settings.
• A camera that fails to power on or respond to reset commands.
• A camera that has reached the end of its lifespan (e.g. battery-powered models after 300-500 charge cycles).

Under the Consumer Rights Act 2015, UK consumers have up to 6 years to claim faulty goods (5 years in Scotland). If your camera is under warranty, contact Arlo’s support team for a replacement or repair. For older devices, consider upgrading to a newer model with improved Wi-Fi capabilities and longer battery life.

Final Tips and Next Steps

If your Arlo camera is still not working after following all the steps above, you may want to explore professional installation options. In the UK, professional installation for a single camera costs between £150-£300, while a 4-camera system can range from £450-£1200. Professional installers can also help address complex Wi-Fi issues or recommend a wired solution if your home’s construction materials severely impact signal strength.
