Why Do Some Apps Work On Mobile Data But Not Wi-Fi?

Why Do Some Apps Work On Mobile Data But Not Wi-Fi?

You’ve been scrolling Instagram the entire morning on your commute to work. The app was working perfectly fine, but at soon as you connected to the office Wi-Fi, the network cut out. Your phone is connected to the Wi-Fi network, so why can’t you access the app? 

This problem has been happening on a few other apps as well, and you can not figure out why. 

Why do some apps work on mobile data but not Wi-Fi?

The Applications/OS Might Be Bugged

Sometimes social media apps (e.g. Facebook, Instagram, WhatsApp, TikTok, etc.) may have bugs that limit certain functions. The app may buffer, crash, and at times, be unable to use Wi-Fi. 

To fix this, you may need to restart your device and app, or completely reinstall the app. 


  • Properly close the app to shut it down. This process differs depending on which iPhone you have, so head to the Apple website for the complete instructions.
  • If your iPhone is glitching, you may need to restart it. This process can be done using your iPhone’s buttons. Since these keys vary from model to model, head to Apple’s article Restart your iPhone for a comprehensive guide on restarting any iPhone.

Step 2: Then, select Remove App

Step 3: Confirm your choice by selecting Delete App

Step 2: Close the app by swiping it up.

The Applications’ Wi-Fi Function Is Disabled

Your phone’s Wi-Fi function may be disabled for certain apps, preventing them from using it. So, it’s a good idea to check that Wi-Fi is enabled for the glitching app. 


This function is not available on iPhones.

Too Many Devices Connected to One Internet/Wi-Fi Network

Your Wi-Fi router may be working but be overcrowded with too many devices. This will cause the network speed to slow dramatically, causing your apps to buffer or struggle to load. 

If you’re using a public network, there may be little you can do to fix this problem. 

However, if you’re using your home Wi-Fi router, try disconnecting any other devices currently connected to it. Devices like streaming sticks, smart TVs, tablets, and phones are still consuming bandwidth in standby mode. So, it’s a good idea to temporarily disable their Wi-Fi. 

It’s also a good idea to restart your router by unplugging it for 30 seconds. Then, re-connect it to power and, if needed, turn it on. 

The Wi-Fi Connection May Be Blocked by the VPN/Third-Party Software

VPNs or third-party apps on your smartphone may limit certain apps’ Wi-Fi connections. This issue is more prevalent when using apps with highly sensitive information, like banking apps. 

So, temporarily turn off your VPN when you need to access these apps. 

We strongly recommend avoiding this when using public networks, as it could make your sensitive information vulnerable to hackers. If you do need to access banking apps or your email when in public spaces, it’s safest to use your cellular data. 

Wrapping Things Up

Apps not working on Wi-Fi can be confusing, especially if they’re working on cellular data. 

The issue could be related to the app’s software glitching or bugs in your smartphone’s OS. Android devices also have a Disable Wi-Fi setting which prevents certain apps from using Wi-Fi, so make sure this setting is disabled. 

The Wi-Fi network may also be overcrowded, causing your apps to stagger. Your smartphone’s VPN could also prevent certain sensitive apps from accessing Wi-Fi.
