Why Won't My Arlo Base Station Sync with My Cameras?
- Internet connection issue
- Base station needs restart
- Ethernet cable problem
Problem Description
Your Arlo Base Station keeps going offline and becoming unreachable through your app. When this happens, you lose the ability to control the Base Station through the Arlo app, scheduled automations, and voice assistants like Alexa and Google Home. This is a common issue with smart hubs devices and usually stems from connectivity problems, outdated firmware, or configuration changes on your network. The steps below walk you through diagnosing and fixing the problem so your Base Station works reliably again.
Symptoms
- Base station shows offline
- Can't add new cameras
- Cameras keep going offline
- LED shows wrong color
- Internet but no Arlo connection
Recognize these? Here's what usually causes it.
Common Causes
- Internet connection issue
- Base station needs restart
- Ethernet cable problem
- Router firewall blocking
- Base station overloaded

Step-by-Step Solution
Check Hub Power and Network Connection
Verify the hub is plugged into a working outlet and the power LED is solid. For ethernet-connected hubs ensure the cable is firmly connected to both the hub and your router with link lights active on both ends. For WiFi hubs check signal strength in the app. A hub without network access cannot communicate with any of its connected devices. If the hub appears offline try a different outlet and ethernet cable before resetting.

Unplug the hub power cable from the wall outlet and wait a full 60 seconds. This allows all background processes to fully terminate and cached data to clear. Plug it back in and wait 2 to 3 minutes for the hub to complete its full boot sequence. Watch for the LED to cycle through startup colors and settle to its normal ready state. Check the app after the LED settles to confirm the hub shows online and paired devices begin reconnecting.
Verify Connected Devices Are Responding
Open the hub app and review the list of all paired devices. Check the status of each device and note any showing offline or unresponsive. For Zigbee and Z-Wave devices, signal strength depends on mesh networking where devices relay signals to each other. If devices far from the hub are offline add a powered repeater device like a smart plug midway between the hub and the distant device. Battery sensors do not act as repeaters.
Re-pair Offline Devices
For devices stuck offline remove them from the app first. Then put the hub into pairing mode through the app by navigating to Add Device. Reset the device to its own pairing mode following its specific instructions, usually by pressing a button for 5 to 10 seconds until an LED blinks. The hub should discover the device within 30 to 60 seconds. Assign it to the correct room and test. Re-create any automations that were linked to the old device entry.
Check and Manage Automations and Scenes
Navigate to the automations or scenes section in your hub app. Review each rule to ensure it still makes sense with your current devices. Delete any automations referencing removed devices. Test critical automations by triggering them manually, for example flipping a sensor to see if linked lights respond. Fix broken automations by reassigning devices. Well-organized automations are the core value of a smart hub.
Update Hub and Device Firmware
Check hub settings for firmware updates. Hub updates often add support for new device types and fix communication bugs. Install the update and allow the hub to restart which can take 5 to 10 minutes. Then check individual device firmware through the hub app. Many Zigbee and Z-Wave devices receive over-the-air updates through the hub. Update any devices with available firmware. After all updates test your key automations.
Quick Solutions
Still having issues? This is usually the deeper cause below.
If pairing fails after multiple attempts, the device may still be registered to a previous account — factory-reset it before trying to add it to a new one.
Arlo base station connects cameras locally even when internet is down - you just can't view remotely.
Pairing failures almost always come down to distance during the initial handshake — manufacturers seriously understate how close you actually need to be.

- Base station needs restart
- Ethernet cable problem
- Router firewall blocking
- Base station overloaded
