Common Reasons Why Internet Keeps Disconnecting

There are several possible reasons why your internet connection might be dropping, leaving you wondering, "why does my internet keep disconnecting?" Let's explore the most common ones:

  • Weak signal: One of the primary reasons for WiFi disconnections is a weak signal. This can be due to your router being too far away from your devices, placed in a poor location, or simply not powerful enough to cover your entire home. To learn how to improve your WiFi signal strength, check out our guide on how to fix weak WiFi signal.
  • Overuse: If your internet connection is shared with many devices, especially during peak hours, it can get overloaded. This congestion can cause your WiFi to keep turning off or result in an internet that keeps going in and out.
  • Interference: WiFi interference is another significant factor that can lead to your WiFi keeps disconnecting. This interference can come from other wireless networks nearby, especially in densely populated areas, as well as from household electronic appliances like microwaves, Bluetooth devices, and cordless phones.
  • Outages: The issue doesn't always have to be on your end. Your internet service provider (ISP) might be experiencing an outage or spike in traffic, both of which can make your internet connection keep dropping and reconnecting.
  • Router issues: Outdated firmware, overheating, or hardware malfunctions can all cause your router to perform poorly or disconnect entirely. Such router issues can be intermittent, making them particularly difficult to diagnose.
  • WiFi adapter issues: The network adapter in your computer or device is responsible for receiving the WiFi signal. Outdated drivers or malfunctions in the adapter itself can cause your internet to keep dropping.
  • Power issues: While less common, unstable power supplies or local power fluctuations can cause your WiFi router to misbehave and your WiFi to keep going in and out.
  • Malware: Routers can be infected with malware, such as the infamous ZuoRAT malware, which infected routers made by Cisco, Netgear, Asus, and DrayTek and caused serious connectivity issues as it allowed attackers to gain access to devices on the same network.

Note: In some cases, a slow internet connection might be mistaken for Wi-Fi disconnections. If you suspect your internet speed is the issue, visit our why is my Internet so slow page for helpful tips and solutions.

How to Troubleshoot and Fix Disconnecting Internet

Knowing the common causes of why your WiFi keeps disconnecting is just the first step towards solving the problem. Determining which specific issue is responsible for your connectivity woes is where the challenge truly begins.

However, this task becomes much more manageable when you approach the troubleshooting process methodically and use a capable WiFi analysis software, like NetSpot, to provide you with the data you need.

1. Start With the Basics

We recommend you start by restarting your router. The classic "turn it off and on again" fix works surprisingly often as it can clear temporary errors and refresh connections. While you're at it, you might as well plug your router into a different outlet (preferably using a different adapter) to rule out power issues.
