Why do I not get notifications when on WIFI?
Not receiving notifications while connected to WiFi is a common issue that many smartphone users face. This can be frustrating as you may miss important alerts from apps and services. In this article, we will outline some potential causes and solutions for missing notifications over WiFi.
Sections in this guide will cover WiFi connectivity issues, notification settings, app restrictions, Do Not Disturb mode, outdated software, network congestion, server problems, and troubleshooting steps. By the end, you should have a better understanding of why notifications may fail over WiFi and some ways to address the problem.
WiFi Connectivity Issues
Sometimes the WiFi connection itself can cause interruptions in receiving notifications on your device. If the WiFi signal is weak or unstable, it may frequently drop out which can prevent apps from connecting to their servers to retrieve notifications. Devices will often attempt to reconnect automatically when the WiFi drops, but this process is not instantaneous. During the reconnection period, no data can be transmitted.
A weak WiFi router signal can cause connectivity issues if you are too far from the router or there are obstructions blocking the signal. Interference from other devices on the same network or neighboring networks on the same channel can also cause WiFi disruptions. Faulty router hardware itself can be the culprit as well.
Checking the WiFi signal strength and router placement can help troubleshoot a spotty connection. Switching to a different wireless channel on the router may also help isolate any interference issues. If the problem persists, the router hardware itself may need to be replaced to maintain a consistent WiFi connection.
Some Android devices like the Google Pixel allow enabling developer options to notify you when the WiFi connection is lost or regained which can help identify any intermittent drops [1]. But this requires using adb commands and is not a standard feature.
Notification Settings
The notification settings on your Android device and individual apps can impact whether you receive notifications when connected to WiFi. At a device level, you can control notifications by going to Settings > Apps & notifications > Notifications. Here you can toggle notifications on or off for specific apps when connected to WiFi.
You can also disable WiFi network notifications entirely by going to Settings > Network & Internet > WiFi > WiFi preferences, and turning off “Notify for public networks.” This will prevent notification icons from appearing when connected to WiFi networks. Some Samsung devices have a similar setting under Settings > Connections > WiFi > Advanced > Network notification that can be disabled.
Within individual apps, you can manage notification settings by going to Settings > Apps & notifications > App info. Select an app and tap Notifications to customize when and how you receive notifications from that app over WiFi. For example, you could disable notifications for an app on WiFi to avoid distractions.
So in summary, adjusting notification settings at both the device level and within apps gives you granular control over which notifications you receive when your Android device is connected to WiFi.

App Restrictions
One common cause of missing notifications on WiFi is app-specific restrictions that block notifications, like battery optimization. Many Android devices have battery optimization settings that restrict background activity for apps in order to preserve battery life. When enabled for an app, battery optimization can prevent it from syncing data or sending notifications in the background when the app isn’t actively in use.
For example, on Samsung devices, the ‘App power management’ settings allow you to choose apps that are ‘put to sleep’ when the screen is off. This prevents selected apps from running background tasks and sending notifications. Similarly, Android has native battery optimization that limits background CPU, network usage, and wake locks to apps that are not actively being used. Enabling this optimization for an app will restrict its ability to send notifications in the background.
To allow apps to send notifications over WiFi, it’s important to disable these battery optimization restrictions. The settings vary across Android devices and versions, but can typically be accessed in the app info or battery settings. Disabling optimization allows apps to freely sync data and send notifications even when the app is not open.
Further troubleshooting may be needed if disabling optimization does not resolve missing notifications for a particular app. But app battery restrictions are one of the most common culprits for lack of notifications over WiFi.
Do Not Disturb Mode
Do Not Disturb mode is a feature available on most smartphones that silences notifications when enabled. When Do Not Disturb is turned on, you will not receive notification sounds or vibrations for calls, messages, or other apps. This can prevent notifications from interrupting you while sleeping, driving, working, or any other situation where you don’t want to be disturbed.
On both Android and iOS devices, Do Not Disturb can be enabled manually or scheduled during certain times. For example, you can set it to turn on automatically overnight while you’re sleeping. Some devices also have options to allow calls or messages from certain contacts even when Do Not Disturb is on.
If you have Do Not Disturb enabled but stop getting WiFi notifications, it’s likely silencing them. Check your Do Not Disturb settings or schedules to see if notifications from any apps are being blocked during certain times. Disabling Do Not Disturb will again allow notifications to come through normally when connected to WiFi.
Outdated Software
One common cause of missing notifications when connected to WiFi is having outdated software on your device. Software updates often contain bug fixes and optimizations that improve the reliability of notifications over WiFi. For example, on Windows 10, an outdated version may fail to deliver notifications properly when connected to certain WiFi networks.
To ensure notifications work correctly, it’s important to keep your operating system and apps updated to the latest versions. On mobile devices like iPhones and Android phones, you can check for system updates in the Settings app. For computers, running regular system updates through Windows Update or the Mac App Store will help. Additionally, checking for app updates in each app’s store/page can fix software bugs preventing notifications.
If you suspect an outdated version of software is to blame, installing any available updates is an important troubleshooting step. Once fully updated, notifications should begin working normally even when on WiFi. Keeping software up-to-date is key for maintaining proper notification functionality.
Network Congestion
Network congestion occurs when there is too much traffic on a network, which can lead to slower speeds and delayed communication between devices. This is a common reason why notifications may be delayed or not arrive promptly when connected to WiFi.
WiFi networks have a limited bandwidth capacity. When many devices are connected and transmitting data at the same time, the network can become congested. This is especially true of public WiFi networks that have many users. With network congestion, there is greater competition for bandwidth, which can cause transmission slowdowns and bottlenecks.
Notification data takes up only a small fraction of network bandwidth. However, when a network is congested, lower priority background tasks like pushing notifications to devices get delayed. The network is focused on transmitting higher priority tasks first, like loading webpages or streaming video. This can result in notifications arriving late or getting dropped from the queue entirely if the network is severely congested.
According to a study on network congestion, even a small increase in traffic on a congested network can have major effects on transmission times and lead to delayed delivery of packets. Notification data travelling over a congested WiFi network experiences these delays and disruptions. Using a less crowded WiFi network or switching to cellular data can provide relief when congestion is causing delayed notifications.
Server Issues
One potential cause of delayed or missed notifications when connected to Wi-Fi is problems with the app servers that push notifications to devices. App developers rely on backend servers to queue and deliver push notifications in a timely manner when new content is available. However, when these servers encounter problems, it can prevent notifications from being sent promptly to devices upon connection.
Issues like server outages, connectivity problems, capacity limits, or configuration errors can all impact the ability of app servers to push notifications. If the servers are unable to communicate with Apple’s APNS service or Google’s FCM service to deliver notifications, users will experience delays or failed notifications until the underlying problem is resolved.
Troubleshooting and monitoring of app servers is required to identify and resolve these backend issues. Developers may need to optimize notification delivery, scale server capacity, and improve resiliency to ensure notifications are pushed reliably at all times. For users experiencing the problem, it typically resolves on its own once the server problems are fixed by the app developer.
According to a discussion on Apple forums, some users have seen delays receiving notifications only when on Wi-Fi, indicating potential server-side issues interfering with push notifications over Wi-Fi connections specifically. Checking with the app developer to see if they are aware of any ongoing server problems can help determine if this is the root cause.
Troubleshooting WiFi Notification Issues
There are various troubleshooting steps you can take if you are not receiving notifications when connected to WiFi on your device:
First, check your device’s notification settings and make sure notifications are enabled for the desired apps. Go to Settings > Notifications and verify notifications are turned on. You may need to check permissions for individual apps as well.
Next, check for any restrictions on notifications in your device’s screen time or parental controls settings. These could be blocking notifications even if they are enabled at the app level. Disable any restrictions to see if that fixes the issue.
It’s also worth restarting your phone or toggling airplane mode on and off. This refreshes all connections and can resolve temporary glitches with WiFi and notifications.
Try manually toggling WiFi as well. Turn it off, wait a few seconds, then turn it back on. Reconnect to the network and see if notifications come through.
Check for any available device or app updates and install them. Older software versions may have bugs affecting WiFi notifications.
If other devices on the same WiFi network are receiving notifications normally, the issue may be isolated to your device. Contact the device manufacturer for additional troubleshooting tips.
As a last resort, reset your network settings or factory reset the device to eliminate any deeper problems. Make sure to backup data first.
