How to Fix Arlo Live View Buffering and Lag
There is nothing more frustrating than trying to check your security camera's live feed, only to be met with a constant "Buffering" message or a choppy, lagging video. When you need to see what's happening at your property right now, these delays are unacceptable. Buffering issues with Arlo cameras almost always point to a network problem, either with your home Wi-Fi or your internet connection.
This guide will walk you through the most effective steps to diagnose and resolve the buffering so you can get a smooth, reliable live stream.
Step 1: Test Your Internet Upload Speed
This is the most critical and often overlooked step. Live streaming from a camera does not depend on your download speed; it relies entirely on your upload speed. You need enough bandwidth to send the video feed from your camera to the Arlo cloud, and then to your phone.
- How to Test: On your smartphone, while connected to the same Wi-Fi network as your cameras, open a web browser and search for "internet speed test".
- What You Need: For a single Arlo camera, you need a minimum of 2 Mbps of upload speed. For multiple cameras, especially if they are 2K or 4K models, you will need significantly more. If your upload speed is consistently below 2-4 Mbps, you will likely experience buffering.
- The Solution: If your upload speed is too low, you will need to contact your Internet Service Provider (ISP) to discuss upgrading your plan.
Step 2: Analyse Your Wi-Fi Signal Strength
The next likely culprit is a weak Wi-Fi connection between the Arlo camera and your router or Arlo SmartHub.
- Check Signal in the App: Go to your camera's settings in the Arlo app. There is usually a Wi-Fi or signal strength indicator. If it shows only one or two bars, the signal is weak.
- Reduce Distance: Physical distance is the biggest enemy of Wi-Fi. The farther the camera is from the router, the weaker the signal.
- Minimise Obstructions: Wi-Fi signals are weakened by physical barriers. Thick walls made of brick or concrete, large metal appliances (like refrigerators), and even water (like in an aquarium) can severely degrade the signal.
Solutions for a Weak Signal:
- Move your router to a more central location in your home.
- Move the Arlo camera closer to the router.
- If you have an Arlo SmartHub, try moving it closer to the camera.
- Invest in a Wi-Fi mesh system or a range extender to provide better coverage to the area where the camera is located.
Step 3: Lower the Video Quality Setting
If upgrading your internet or improving your Wi-Fi isn't an immediate option, you can reduce the amount of bandwidth the camera requires by lowering its streaming quality.
- Open the Arlo app and go to Settings > My Devices.
- Select the camera that is buffering.
- Tap on Video Settings.
- You will see options for quality, such as "Best Video", "Optimised", and "Best Battery Life".
- Choose a lower setting (e.g., switch from "Best Video" to "Optimised"). This will reduce the resolution and bitrate, making it easier for the camera to stream over a weaker connection.
Step 4: Reboot Your Network and Camera
Finally, a simple reboot can clear up temporary network congestion or software glitches.
- Unplug your Arlo camera (or remove its battery).
- Unplug your modem and your Wi-Fi router (and Arlo SmartHub, if you have one).
- Wait for 60 seconds.
- Plug the modem in first and wait for it to fully connect.
- Plug in the router and wait for it to broadcast its signal.
- Power your Arlo camera back on.
By systematically addressing your internet speed, Wi-Fi coverage, and in-app settings, you can eliminate the frustrating buffering and enjoy a smooth, real-time view from your Arlo security camera.
