And while router placement, interference, and firmware glitches often get the blame, sometimes the real troublemaker is your smartphone. In this post, we’ll dive into whether an iPhone can actually block WiFi from Arlo cameras, why it might happen, and—most importantly—how to fix it. Whether you’re a tech newbie or a seasoned DIYer, you’ll walk away with practical, no-nonsense tips to keep your home security system running smoothly.

Understanding the Basics: How Arlo Cameras and iPhones Share Your Network

How Arlo Cameras Connect to WiFi

Arlo cameras are designed for simplicity. Most models—like the Arlo Pro 4, Arlo Ultra, or even the older Arlo Pro 2—connect to your home WiFi using a 2.4 GHz or 5 GHz band. They don’t require a base station (on newer models), making setup easier. The camera sends video data to the cloud via your router, and you access it through the Arlo app on your iPhone or other devices.

But here’s the catch: These cameras are smart but not smartphone-aware. They don’t know your iPhone is nearby, nor do they adjust their signal strength based on your phone’s activity. So when your phone starts hogging bandwidth or interfering with the same WiFi band, the camera can get pushed to the back of the line.

iPhone’s Role in Your Home Network

Your iPhone isn’t just a phone—it’s a mini-computer constantly connected to your WiFi. It’s streaming music, downloading updates, syncing iCloud, and running background apps. All of this activity uses bandwidth and can impact network performance.

For example, if you’re downloading a 2GB iOS update while your Arlo camera is trying to upload a 10-minute HD video, your router might prioritize the phone’s download. This can cause the camera to buffer, disconnect, or show “WiFi lost” errors in the Arlo app.

Shared Bandwidth and Signal Interference

Both your iPhone and Arlo camera likely use the same WiFi band—usually 2.4 GHz for better range, or 5 GHz for speed. But 2.4 GHz is crowded. It’s used by microwaves, baby monitors, Bluetooth devices, and even neighboring networks. Your iPhone, constantly scanning for the best signal, can unintentionally create interference.

Here’s a real-life example: Sarah from Portland had an Arlo Pro 4 in her backyard. Every time her family used iPhones near the sliding door, the camera would disconnect. After testing, she realized the phones were connecting to the 2.4 GHz band and creating a “signal storm” that disrupted the camera’s weaker signal.

Can Your iPhone Actually Block WiFi From Arlo Cameras?

Direct Blocking: Is It Possible?

Let’s cut to the chase: No, your iPhone cannot directly “block” WiFi from Arlo cameras like a firewall or jammer. It doesn’t have the hardware or software to shut down another device’s WiFi connection. But—and this is a big but—it can indirectly cause the camera to lose connection through network congestion, interference, or router prioritization.

Think of it like a highway. Your router is the toll booth. Your Arlo camera and iPhone are cars. If the iPhone (a big SUV) takes up two lanes with a massive download, the camera (a small sedan) might get stuck in traffic or forced to exit early. That’s not blocking—it’s congestion.

Common Scenarios Where iPhones Cause WiFi Disruptions

Here are real situations where an iPhone can make your Arlo camera go offline:

• Large Downloads/Updates: iOS updates, app downloads, or iCloud backups can saturate your bandwidth.
• Video Streaming: Watching Netflix or YouTube on your phone while the camera uploads video.
• Background App Refresh: Multiple apps syncing data in the background.
• Proximity to Camera: Holding your iPhone near the camera (especially on 2.4 GHz) can cause signal reflection or absorption.
• WiFi Calling or Personal Hotspot: Using these features can overload your router’s capacity.

Case Study: The “iPhone in the Kitchen” Problem

Mark in Austin installed an Arlo camera in his kitchen to monitor his dog. Every evening, when his wife used her iPhone for FaceTime calls, the camera would disconnect. After troubleshooting, we discovered the issue: Her phone was on 2.4 GHz, and the camera was also on 2.4 GHz. The FaceTime call (high bandwidth) caused the router to deprioritize the camera’s upload. Switching the phone to 5 GHz fixed the issue instantly.

How to Diagnose iPhone-Related WiFi Issues With Arlo Cameras

Step 1: Check Your Arlo App for Error Messages

The first clue is in the Arlo app. Look for:

• “WiFi Lost” or “Connection Failed” alerts
• Camera showing “Offline” status
• Intermittent video feeds (freezing or buffering)

If these happen only when you’re using your iPhone nearby, you’ve found your pattern.

Step 2: Use Your Router’s Admin Panel to Monitor Bandwidth

Log into your router (usually via 192.168.1.1 or 192.168.0.1). Look for:

• Connected Devices: See which devices are online and their bandwidth usage.
• Bandwidth Usage Charts: Check if your iPhone is using high bandwidth when the camera disconnects.
• WiFi Channel Congestion: Some routers show channel usage (e.g., Netgear, Asus).

Tip: Use a free tool like WiFi Analyzer (iOS) to see which channels are crowded.

Step 3: Run a WiFi Speed Test

Use an app like Speedtest by Ookla (free on the App Store) to check your network speed when:

1. The Arlo camera is connected and working
2. Your iPhone is idle
3. Your iPhone is downloading/updating

If speed drops by 50% or more during downloads, your iPhone is likely causing congestion.

Step 4: Test the Camera Without the iPhone

The simplest test: Turn off your iPhone’s WiFi (or put it in Airplane Mode). If the Arlo camera stays online, your phone was part of the problem.

For a more thorough test, use another device (like a tablet or laptop) to see if the camera disconnects when that device is active. This helps isolate whether it’s iPhone-specific or just high-bandwidth usage.

Practical Fixes to Prevent iPhone-Related WiFi Disruptions

1. Switch Your iPhone to 5 GHz (If Possible)

Most modern iPhones (iPhone 6 and newer) support dual-band WiFi (2.4 GHz and 5 GHz). The 5 GHz band is faster and less crowded, making it ideal for high-bandwidth tasks.

How to check your iPhone’s WiFi band:

• Go to Settings > WiFi
• Tap the (i) icon next to your network
• Look for the Frequency or Channel (if it says “36,” “149,” etc., you’re on 5 GHz)

Pro Tip: If your router has a separate network name for 5 GHz (e.g., “HomeNetwork_5G”), connect your iPhone to that. If not, your router should automatically assign the best band, but you can force it by temporarily turning off 2.4 GHz in the router settings (not recommended for long-term).

2. Limit Background Activity on Your iPhone

Reduce your phone’s bandwidth usage:

• Turn off Background App Refresh: Settings > General > Background App Refresh (toggle off for non-essential apps).
• Disable Automatic Downloads: Settings > App Store > Turn off “App Downloads” and “Updates.”
• Schedule iOS Updates: Settings > General > Software Update > Enable “Automatic Updates” but do it during off-hours (e.g., overnight).
• Use Low Data Mode: Settings > Cellular > Cellular Data Options > Data Mode (set to “Low Data Mode”).

3. Prioritize the Arlo Camera in Your Router

Many routers let you set Quality of Service (QoS) rules to prioritize certain devices.

Example (on a TP-Link router):

1. Log into the router admin panel
2. Go to Advanced > QoS
3. Enable QoS and set a high priority for your Arlo camera (find its MAC address in the Arlo app under “Device Info”)
4. Set a lower priority for devices like iPhones

This ensures the camera gets bandwidth first, even when your phone is active.

4. Optimize Router Placement and WiFi Channels

Even if your iPhone isn’t the main issue, a weak WiFi signal can make problems worse.

• Move the router closer to the camera (ideally within 30 feet with one wall max).
• Elevate the router (place it on a shelf, not on the floor).
• Change the WiFi channel to a less crowded one (use WiFi Analyzer to find the best channel).
• Use a WiFi extender or mesh system (like Google Nest WiFi or Eero) if the camera is far from the router.

5. Update Firmware and Reset Network Settings

Outdated firmware can cause compatibility issues.

• Update your Arlo camera: Arlo app > Device Settings > Firmware Update.
• Update your router: Check the manufacturer’s website for firmware updates.
• Reset network settings on your iPhone: Settings > General > Reset > Reset Network Settings (this clears saved WiFi passwords, so have them handy).

Advanced Solutions: When Simple Fixes Aren’t Enough

Use a Dedicated 2.4 GHz Network for IoT Devices

For tech-savvy users, creating a separate 2.4 GHz network for smart home devices (like Arlo cameras, smart plugs, etc.) can solve interference issues.

How to do it:

1. Log into your router
2. Create a new 2.4 GHz network (e.g., “Home_IoT”)
3. Set a strong password and use WPA2/WPA3 encryption
4. Connect your Arlo camera to this network
5. Keep your iPhone on the 5 GHz main network

This keeps your phone and camera on separate bands, eliminating competition.

Invest in a WiFi 6 Router

WiFi 6 (802.11ax) routers handle multiple devices better than older models. They use OFDMA to split bandwidth efficiently and BSS Color to reduce interference from neighboring networks.

If you have 10+ smart devices (including iPhones, tablets, cameras), a WiFi 6 router like the Netgear Nighthawk AX8 or Asus RT-AX88U can make a huge difference.

Use Ethernet Backhaul (For Base Station Cameras)

Older Arlo models (like Pro 2) use a base station. If possible, connect the base station to your router via Ethernet cable instead of WiFi. This gives the camera a direct, stable connection and removes it from the wireless competition entirely.
