Dig Into Your Arlo's Wi-Fi Settings

Ensure Your Camera is on the 2.4GHz Band

Arlo cameras (except Arlo Pro 6) require a 2.4GHz Wi-Fi connection for stable performance. If your router uses a single SSID for both 2.4GHz and 5GHz bands, the camera may inadvertently connect to the 5GHz network, which has limited range and can cause app disconnection. To check your camera's current Wi-Fi band:

  1. Open the Arlo Secure app.
  2. Navigate to Device Health → Wi-Fi Band.
  3. If the camera is on 5GHz, manually switch it to 2.4GHz. For Arlo Pro 6 models, use the Wi-Fi Troubleshooting Tool in the app to enforce 2.4GHz mode.

Use the Wi-Fi Troubleshooting Tool

Arlo's built-in Wi-Fi Troubleshooting Tool helps identify connectivity issues:

  1. Open the Arlo Secure app.
  2. Go to Device Health → Wi-Fi Troubleshooting Tool.
  3. Follow the on-screen prompts to test signal strength, check for interference, and optimize placement.

If the tool recommends moving the camera closer to the router, do so immediately. Arlo cameras require a minimum signal strength of -70dBm for reliable connectivity. If the signal is weaker than this, consider adding a Wi-Fi extender or reducing obstructions between the camera and router.

Update Firmware

Outdated firmware can cause the Arlo app to fail connecting to your camera. To ensure your camera has the latest firmware:

  1. Open the Arlo Secure app.
  2. Navigate to Settings → Device Firmware.
  3. If an update is available, follow the on-screen instructions to install it. For Arlo Pro 6 models, the app will automatically download and install updates over-the-air. For Arlo Essential 2K models, ensure the camera is connected to a stable 2.4GHz network during the update.

Check for Interference

Wi-Fi interference from other devices (e.g. microwaves, cordless phones) can disrupt the Arlo app's connection. To minimize interference:

  • Move the camera away from other wireless devices.
  • Avoid placing the camera near metal objects or thick walls.
  • Use the Signal Strength Meter in the app to identify areas with weaker signals.

Port Forwarding for Remote Access

If you're unable to access your Arlo camera remotely via the app, ensure port forwarding is correctly configured. Arlo requires the following ports to be open on your router:

  • TCP 80 (HTTP)
  • TCP 443 (HTTPS)
  • UDP 53 (DNS)
  • UDP 67-68 (DHCP)
  • TCP 1900 (UPnP)
  • TCP 8080 (Arlo SmartHub)

To configure port forwarding:

  1. Access your router's admin panel (usually via 192.168.1.1 or your ISP's default gateway).
  2. Navigate to the Port Forwarding section.
  3. Add the ports listed above, directing traffic to your router's local IP address (e.g. 192.168.1.1).

Note: Virgin Media Hub 5x users may encounter double NAT issues that prevent remote access. If you're using this router, consider contacting Virgin Media for specific port forwarding instructions.

Factory Reset and Re-Pairing

Understanding the Root Cause

Arlo app disconnection often stems from Wi-Fi band mismatch, outdated firmware, or incorrect pairing. UK-specific challenges, such as Virgin Media's double NAT or EE/Three/Vodafone's CGNAT, can also prevent remote access. Additionally, Arlo cameras require a 2.4GHz Wi-Fi connection for stable performance. If your router uses a single SSID for both bands, the camera may inadvertently connect to the 5GHz network, which has limited range. Firmware updates are critical for resolving compatibility issues, and model-specific resets can help re-establish the connection.

Prevention and Long-Term Care

To prevent future Arlo app disconnections, follow these best practices:

  • Regularly update firmware: Check for updates in the Arlo Secure app under Settings → Device Firmware.
  • Optimize Wi-Fi placement: Ensure your camera is within 10 metres of the router and free from obstructions.
  • Monitor battery health: For battery-powered models, check the Battery Level in the app under Device Health → Battery. Replace the battery if it's below 20%.
  • Use the Wi-Fi Troubleshooting Tool: Run the tool periodically to identify and resolve connectivity issues.

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.

Replacement Decisions

If your Arlo camera is beyond repair or no longer supported, consider the following:

  • Battery-powered cameras: Replace after 3-5 years, as battery capacity degrades over time.
  • Wired cameras: Replace after 5-8 years, considering sensor degradation and firmware end-of-life.
  • UK Consumer Rights: 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 the retailer for repair or replacement.

Arlo cameras typically last 3-5 years for battery-powered models and 5-8 years for wired models. If your camera is over 5 years old and experiencing persistent connectivity issues, it may be time to consider a replacement.

If the camera fails to re-pair, check for firmware updates in the app under **Settings → Device Firmware**. For Arlo Essential Indoor models, press and hold the **Sync button** on the back for 20-30 seconds until the LED blinks amber.

Arlo cameras require a stable 2.4GHz Wi-Fi connection for reliable performance. If your router uses a dual-band setup with a single SSID, the camera might inadvertently connect to the 5GHz band, which has limited range. To fix this, access your router's admin panel (usually via 192.168.1.1 or your ISP's default gateway) and create a **separate SSID for 2.4GHz**. Rename it to something like 'Arlo-2.4GHz' to ensure the camera connects to the correct network. For Virgin Media Hub 5x users, be aware of **double NAT** issues that can prevent remote access. If your camera is on a 5GHz network, manually switch it to 2.4GHz via the Arlo Secure app under **Device Settings → Wi-Fi Band**.

Arlo cameras use **2.4GHz Wi-Fi only** (except Arlo Pro 6 models, which support dual-band). If your camera is connected to a 5GHz network, the app may fail to communicate with the device. To check your camera's current Wi-Fi band, open the Arlo Secure app, go to **Device Health → Wi-Fi Band**, and ensure it's connected to 2.4GHz. If it's on 5GHz, manually switch it to 2.4GHz. For Arlo Pro 6 models, access the **Wi-Fi Troubleshooting Tool** in the app and select **2.4GHz mode**. If your router uses a single SSID for both bands, explicitly select the 2.4GHz network during setup. If the issue persists, check for firmware updates in **Settings → Device Firmware**.

Arlo cameras with battery power (e.g. Arlo Essential 2K) require at least **20% battery life** for stable connectivity. Open the Arlo Secure app, go to **Device Health → Battery Level**, and ensure the battery is above 20%. If it's below this threshold, charge the camera fully before proceeding. For Arlo Pro 6 models, check the **Battery Health Monitor** in the app under **Device Settings → Battery**. If the battery is degraded (e.g. less than 50% capacity), consider replacing it. If the camera is wired (e.g. Arlo Essential Indoor), check the transformer voltage at the junction box—it must supply **16-24V AC**. If the voltage is outside this range, consult a qualified electrician.
