my arlo pro 4 spotlight camera keeps going offline in the app, it's fully charged and not far from the base station.

Diagnosis

The Arlo Pro 4 is designed to connect directly to your Wi-Fi network, but it is highly sensitive to 2.4GHz frequency congestion. When the camera frequently drops offline despite a full battery and proximity to the hub, you are likely experiencing "signal shadowing" or "co-channel interference." This occurs when the router and the Arlo hardware are placed too close together, causing the wireless signals to overlap and create "noise" that drowns out the camera's heartbeat signal to the cloud. Furthermore, because the Pro 4 utilizes a specific 2.4GHz band for long-range penetration, it can be knocked offline by other household devices like microwave ovens, baby monitors, or cordless phones operating on the same frequency. If you see the LED on the front of the camera flashing amber or if the app reports "Device Offline" while the battery is at 100%, the issue is almost certainly a handshake failure between the camera's wireless radio and your router's DHCP assignment, rather than a hardware failure.

How to Fix It

To stabilize the connection and stop the intermittent offline status, follow these precise steps to optimize your network environment:

1. Physical Separation: Move your Arlo SmartHub or Wi-Fi router so there is a minimum of 6 feet (approximately 2 meters) of open air between them. If they are currently stacked on the same shelf or sitting side-by-side, the electromagnetic interference will cause the camera to drop packets.
2. Power Cycle the Ecosystem: Unplug the power cable from the back of the Arlo SmartHub (if used) and your Wi-Fi router. Wait exactly 60 seconds to allow the capacitors to fully discharge. Plug the router back in first, wait for the internet light to turn solid, and then plug in the Arlo hub.
3. Adjust Router Channel: Log into your router's admin panel (usually 192.168.1.1 or 192.168.0.1). Navigate to the Wireless Settings for the 2.4GHz band. Change the "Channel" from "Auto" to a fixed channel—specifically channel 1, 6, or 11. These are the non-overlapping channels that provide the most stable connection for Arlo hardware.
4. Refresh Device Connection: In the Arlo app, go to Settings > My Devices > [Your Camera] > Device Information. If the signal strength is listed as "Poor" or "Fair," move the camera 2-3 feet closer to the router or hub to see if the status changes to "Strong."

If That Didn't Work

• Disable "Smart Connect" or Band Steering: Many modern routers combine 2.4GHz and 5GHz into one SSID. The Arlo Pro 4 only supports 2.4GHz. If your router uses Band Steering, the camera may try to "hop" to the 5GHz band, fail, and go offline. Create a separate guest network specifically for your cameras using only the 2.4GHz band.
• Update Firmware via Hard Reset: If the camera is stuck in a boot loop, perform a factory reset. Use a paperclip to press and hold the reset button on the bottom of the camera for 15 seconds until the LED flashes amber. Then, re-add the camera to the app to force the latest firmware version to install.
• Check for Physical Obstructions: Ensure the camera is not mounted directly against a brick wall, metal siding, or near a large mirror. These materials reflect 2.4GHz signals and create "dead zones" immediately around the camera, leading to intermittent connectivity.
• Assign a Static IP: Use your router's DHCP reservation settings to assign a permanent IP address to the camera's MAC address. This prevents the camera from going offline when the router attempts to rotate IP addresses (DHCP lease expiration).

Heads Up

• Avoid Metal Enclosures: Never place your SmartHub inside a media cabinet or behind a television; the metal shielding will degrade the signal by up to 50%.
• Battery Drain Warning: Frequent "offline" and "reconnecting" cycles will drain your battery much faster than normal recording, as the camera spends more energy searching for a signal than transmitting video.
• Weather Seal Check: If you are resetting the camera, ensure the rubber charging port cover is seated perfectly flush. Even a tiny gap allows moisture to enter, which can corrode the wireless antenna and cause permanent connection drops.
• Update Frequency: Always keep your Arlo app updated to the latest version from the App Store or Play Store, as connectivity patches are frequently released to improve 2.4GHz stability.
