If your Arlo Pro 4 can't connect to base station, you're not alone—this is one of the most common setup and maintenance issues Arlo users encounter. Whether you're setting up your camera for the first time or suddenly lost connection after months of reliable use, this guide will walk you through proven troubleshooting steps to restore the link between your Arlo Pro 4 and its SmartHub or base station. Most connection problems stem from power issues, network interference, firmware mismatches, or distance problems, and nearly all can be resolved without professional help.
Quick Fixes to Try First
Before diving into deeper troubleshooting, these rapid checks resolve the majority of Arlo Pro 4 can't connect to base station cases in under five minutes:
1
Verify Base Station Power and Internet: Check that your Arlo SmartHub or base station shows a solid blue LED light. If it's amber or blinking, unplug the power adapter for 10 seconds, then reconnect. Confirm your router's internet connection is active by testing another device on the same network.
2
Check Camera Battery Level: Open the Arlo app, tap your Pro 4 camera, and view the battery percentage. If below 15%, remove the battery and charge it fully using the Arlo charging cable. A depleted battery is the leading cause of sudden disconnections.
3
Reduce Distance and Obstructions: Move your Arlo Pro 4 within 10 feet of the base station during setup or reconnection. Thick walls, metal appliances, and mirrors significantly weaken the proprietary wireless signal Arlo cameras use.
4
Restart Both Devices Simultaneously: Power off your base station by unplugging it, then remove and reinsert your Pro 4's battery. Wait 30 seconds, reconnect base station power, and allow two minutes for full boot-up before checking the app for reconnection.
Advanced Troubleshooting Steps
If basic steps don't resolve why your Arlo Pro 4 can't connect to base station, proceed with these targeted solutions:
5
Sync Using the Physical Sync Button: Press the Sync button on your base station for about two seconds until the LED blinks blue. Within two minutes, press and hold the Sync button on your Pro 4 camera until the LED blinks amber and blue. A rapidly blinking blue light followed by solid blue confirms successful pairing.
6
Update Firmware Through the Arlo App: Launch the app, navigate to Settings > My Devices > [Your Base Station] > Device Info > Firmware > Update. Repeat for the Pro 4 camera under My Devices. Firmware incompatibilities frequently block reconnection after automatic updates fail silently.
Warning: Do NOT remove your Arlo Pro 4 from the app unless you've exhausted all other options. Deleting the device erases your cloud recording history, activity zones, and custom settings. Only remove and re-add the camera if sync attempts repeatedly fail after three complete cycles.
7
Factory Reset the Base Station: Use a paperclip to press and hold the Reset button on the base station for 10 seconds until all LEDs flash. You'll need to re-add all cameras and reconfigure settings, but this resolves persistent pairing corruption that standard restarts cannot fix.
8
Check for 2.4GHz/5GHz Conflicts: The Arlo Pro 4 connects directly to the base station, but the base station connects to your router. If your router automatically switches between bands, assign the base station to 2.4GHz in your router settings for maximum stability, or disable band steering temporarily during setup.

Why does my Arlo Pro 4 keep disconnecting from the base station?
Intermittent disconnections typically indicate insufficient battery charge, firmware bugs, or signal interference from other wireless devices. Update both devices to the latest firmware, charge the battery above 50%, and position the base station away from microwaves, baby monitors, and Bluetooth speakers. If problems persist after these steps, the camera's wireless radio may require replacement.
Can I use Arlo Pro 4 without a base station?
The Arlo Pro 4 supports direct Wi-Fi connection to your router, bypassing the base station entirely. In the Arlo app, select "Connect without SmartHub" during setup. However, you'll lose local storage capabilities, advanced AI detection features, and the dedicated wireless bandwidth that base stations provide for more reliable performance.
How far can the Arlo Pro 4 be from the base station?
Arlo specifies 300 feet line-of-sight range, but real-world performance varies dramatically. Indoors with standard construction, expect 50-100 feet. Concrete, brick, and metal reduce this significantly. For optimal reliability, maintain visual line-of-sight between camera and base station when possible, or install an Arlo Wi-Fi range extender for challenging layouts.
