- WiFi SSID or password changed and Arlo devices still have old credentials
- New router uses 5GHz only or band steering pushing devices to unsupported band
- Arlo SmartHub connected via Ethernet lost connection because new router has different ports
Problem Description
After replacing your WiFi router, upgrading to mesh WiFi, or changing your WiFi password, all your Arlo cameras show offline. The reconnection process depends on whether your cameras connect directly to WiFi or through an Arlo SmartHub or base station. WiFi-direct cameras like the Arlo Pro 4 and Essential each need individual reconnection. Hub-based cameras only require reconnecting the hub since the cameras communicate with the hub via their own radio frequency not your WiFi. This distinction confuses many users leading to unnecessary work.
Symptoms
- All Arlo cameras show offline in the Arlo app after router or password change
- Arlo SmartHub or base station shows offline LED pattern
- WiFi-direct cameras like Arlo Pro 4 each show disconnected individually
- Arlo app shows devices as unavailable with no live stream
- Base station Ethernet LED is lit but internet LED is not
- Cameras were all working before the router change and no other changes were made
Recognize these? Here's what usually causes it.
Common Causes
- WiFi SSID or password changed and Arlo devices still have old credentials
- New router uses 5GHz only or band steering pushing devices to unsupported band
- Arlo SmartHub connected via Ethernet lost connection because new router has different ports
- New router uses WPA3 which Arlo WiFi-direct cameras do not support
- New router uses a different IP subnet causing network configuration mismatch
- Router MAC address filtering blocking Arlo device connections
Most fixes happen in the first 3 steps.
Do not factory reset your Arlo cameras just because they went offline after a router change. A factory reset is unnecessary and erases all camera settings. Simply reconnecting to the new WiFi network preserves all your motion zones, sensitivity settings, recording schedules, and modes.
Tools & Requirements
Step-by-Step Solution
Determine Your Arlo Setup Type
First identify whether your cameras connect through an Arlo SmartHub or base station or directly to WiFi. If you have a white Arlo SmartHub or base station connected to your router via Ethernet your cameras talk to the hub not to WiFi. You only need to get the hub back online. If you have WiFi-direct cameras like Arlo Pro 4, Arlo Essential, or Arlo Go each camera connects to your WiFi individually and must be reconnected separately.
Reconnect SmartHub or Base Station
If you have a hub-based system verify the Ethernet cable is plugged from the SmartHub to your new router. Check that the internet LED on the SmartHub is solid green. If not try a different Ethernet port on the router and a different cable. Once the hub is online via Ethernet all cameras paired to it will come online automatically within 2 to 5 minutes since they communicate with the hub via radio not WiFi.
Reconnect WiFi-Direct Cameras
For cameras that connect directly to WiFi open the Arlo app. Tap the offline camera. If a Reconnect WiFi option appears use it. If not go to Settings then Connection then Change WiFi Network. The app will guide you to press the sync button on the camera. Select your new WiFi network and enter the password. Repeat for each WiFi-direct camera. They must be within range of your router during this process.
Use Same SSID For Instant Reconnection
If you have not set up your new router yet configure it with the exact same SSID and password as the old router. Hub-based cameras will reconnect as soon as the hub gets internet via Ethernet. WiFi-direct cameras will reconnect automatically within 5 minutes as they try to join the remembered network name. This is by far the fastest method especially with many cameras.
Verify All Cameras Are Online
After reconnecting open the Arlo app and check each camera status. A green dot means online. Tap each camera and verify live view works. Check that motion detection is triggering by walking in front of each camera and confirming a recording appears in the library. If any camera remains offline try power cycling it by removing the battery for 10 seconds and reinserting.
Quick Solutions
Still having issues? This is usually the deeper cause below.
This usually happens right after a router reboot or ISP change — the device rejoins the network but drops its cloud session silently.
When buying a new router write down your current WiFi SSID and password before disconnecting the old router. Configuring the new router with identical credentials saves enormous time with IoT devices. This applies to all smart home brands not just Arlo.
Most WiFi drop-offs happen right after a router reboot or ISP swap — the device reconnects to the network but silently loses its cloud registration.
- WiFi SSID or password changed and Arlo devices still
- New router uses 5GHz only or band steering pushing
- Arlo SmartHub connected via Ethernet lost connection
- New router uses WPA3
- New router uses a different IP subnet
Before you go — try one of these (they fix most cases).
