Step-by-Step Troubleshooting

Check Your Arlo Camera's Wi-Fi Band Settings

Arlo cameras require a stable 2.4GHz Wi-Fi connection for firmware updates. Even if your router supports dual-band, ensure your camera is connected to the correct network:

  1. Open the Arlo Secure app → Tap the camera icon → Go to Device Settings.
  2. Under Wi-Fi Network, confirm the camera is connected to a 2.4GHz network. If it's on 5GHz, change the setting to 2.4GHz.
  3. For Arlo Pro 6 models, ensure the camera is connected to either 2.4GHz or 5GHz (both are supported). Avoid networks with high latency or signal degradation.

Is your camera battery-powered or wired?

  • Battery-powered → Check battery level in the app — charge fully if below 20%
  • Wired → Check the transformer voltage at the junction box — must supply 16-24V AC

Use the Arlo Secure App's Wi-Fi Troubleshooting Tool

The Arlo Secure app includes a Wi-Fi Troubleshooting Tool that diagnoses signal strength and interference issues:

  1. Open the app → Tap the camera icon → Go to Device Health → Select Wi-Fi Troubleshooting Tool.
  2. Follow the prompts to test signal strength. A signal below -65dBm may cause update failures.
  3. If interference is detected, move your camera closer to the router or reduce obstacles between them.

Update Your Arlo Firmware Manually

If the automatic update fails, try a manual firmware update via the Arlo Secure app:

  1. Ensure your camera is connected to a stable 2.4GHz Wi-Fi network.
  2. Open the Arlo Secure app → Tap the camera icon → Go to Device Settings → Select Firmware Update.
  3. If an update is available, tap Update Now. Allow 5-10 minutes for the process to complete.
  4. Avoid interrupting the update — a power loss or network drop may brick the camera.

Adjust Your Router's Port Forwarding Settings

Some routers block Arlo's update servers by default. To fix this:

  1. Access your router's admin panel (usually via a web browser at 192.168.1.1 or similar).
  2. Navigate to Advanced Settings → Port Forwarding.
  3. Add the following port mappings:
  • TCP 80, 443, 8080, 8880, 8881
  • UDP 53, 67, 68, 80, 8080, 8880, 8881
  1. Save changes and restart your router.

Re-pair Your Arlo Camera

If firmware updates still fail, re-pairing the camera may resolve connectivity issues:

  • For Arlo Pro 6: Press and hold the Sync button for 10 seconds until the LED blinks blue.
  • For Arlo Essential 2K: Press the Pairing button on the top for 15-30 seconds until the LED turns solid blue then blinks amber.

After resetting, re-pair the camera via the Arlo Secure app by selecting Add Camera → Choose the correct model → Follow the setup wizard.

  2. Provide your camera model, firmware version, and diagnostic logs.
  3. Arlo's team will guide you through advanced recovery steps, including rolling back to a previous firmware version if needed.

Understanding Why Your Arlo Firmware Update Failed

Firmware updates can fail due to a combination of factors specific to Arlo devices. Common causes include:

  • Weak Wi-Fi signal: Signal strength below -65dBm may prevent the camera from downloading updates.
  • Incompatible Wi-Fi bands: Arlo Essential models only support 2.4GHz networks — connecting to 5GHz may cause failures.
  • Router firewall settings: Some ISP routers block ports required for firmware updates, requiring manual port forwarding.
  • Low battery during update: Battery-powered models must be charged to at least 20% before updating.
  • Transformer voltage issues: Wired models require a transformer supplying 16-24V AC — low voltage may disrupt the process.

UK-specific challenges, such as Virgin Media's double NAT or CGNAT on mobile broadband, can also interfere with updates. Ensure your router is configured correctly for Arlo devices.

Prevent Future Firmware Update Issues

To avoid firmware update failures, follow these best practices:

  • Maintain strong Wi-Fi signal: Keep your camera within 10-15 metres of your router, avoiding thick walls or metal obstacles.
  • Charge batteries fully: For battery-powered models, ensure the battery is above 20% before updating.
  • Use the correct Wi-Fi band: Arlo Essential models must connect to 2.4GHz networks — avoid 5GHz.
  • Update your router firmware: Ensure your router's firmware is up to date to support Arlo's update servers.
  • Monitor device health: Use the Arlo Secure app's Battery Health Monitor to track battery degradation over time.

Full disclosure: we built scOS to address exactly this — the frustration of cameras that depend on Wi-Fi to function but fail during firmware updates. scOS uses permanently powered cameras connected via ethernet, eliminating battery and Wi-Fi limitations.

When to Consider Replacement

If your Arlo camera fails to update despite following all troubleshooting steps, it may be nearing the end of its lifespan:

  • Battery-powered models (e.g. Arlo Essential 2K): Typically last 3-5 years. Battery degradation after 300-500 cycles may prevent updates.
  • Wired models (e.g. Arlo Pro 6): Last 5-8 years but may face sensor or firmware end-of-life issues.
  • UK consumer rights: Under the Consumer Rights Act 2015, you have up to 6 years to claim faulty goods (5 years in Scotland). If your camera is under warranty, contact Arlo support for replacement options.

Professional installation for new systems starts at £150-£300 per camera. Consider upgrading to a wired system for greater reliability, especially in UK homes with complex layouts or poor Wi-Fi coverage.

Frequently Asked Questions

Firmware updates can fail due to unstable internet, low battery, or incompatible router settings. Start by checking your camera's battery level in the Arlo Secure app — ensure it's above 20%. If using a solar or battery model, charge fully before updating. Next, verify your Wi-Fi signal strength via the app's **Wi-Fi Troubleshooting Tool**. If signal is weak (←65dBm), move your camera closer to the router. Finally, ensure your router isn't blocking Arlo's update servers by checking firewall settings in your router's **Advanced Settings → Port Forwarding**. If unsure, reset your router and try again.

To reset an Arlo Pro 6 camera, press and hold the **Sync button** on the camera for 10 seconds until the LED blinks blue. For Arlo Essential 2K models, press the **Pairing button** on the top for 15-30 seconds until the LED turns solid blue then blinks amber. After resetting, reconnect the camera to your 2.4GHz Wi-Fi network via the Arlo Secure app. If your router uses a single SSID for both bands, ensure the camera connects to the correct network (often named 'Arlo-2.4GHz'). Avoid 5GHz networks for Arlo Essential models, as they only support 2.4GHz.

Battery-powered Arlo cameras require sufficient charge during firmware updates. If your camera's battery is below 20%, the update may fail. Check battery health in the Arlo Secure app under **Device Health → Battery Status**. For solar models, ensure the solar panel is unobstructed and the battery is fully charged. If your camera is wired, verify the transformer voltage at the junction box using a multimeter — it must supply 16-24V AC. Low voltage can disrupt the update process.

If your Arlo camera is connected to a Virgin Media Hub 5x or similar ISP router, double NAT can block firmware updates. To fix this, access your router's **Advanced Settings → Network → NAT Settings** and disable double NAT if available. If you can't change this, contact your ISP for assistance. For EE/Three/Vodafone mobile broadband users, note that CGNAT prevents port forwarding — use the Arlo Secure app's **Wi-Fi Troubleshooting Tool** to ensure your camera is connected to the correct Wi-Fi band (2.4GHz only for Arlo Essential models).
