Reasons Wi-Fi Connections Drop

Solutions to Dropped or Lost Wi-Fi Connections

Was this page helpful?

On home or public wireless networks, your Wi-Fi connection might drop unexpectedly for no obvious reason. Wi-Fi connections that keep dropping can be especially frustrating.

Dropped Wi-Fi connections are much more common than you might think, and fortunately, solutions do exist.

Consult this checklist to determine why it is happening and how to prevent it:

Wi-Fi Radio Interference

Radio signals from various consumer electronic products around your house or in the vicinity of your device and the router, can interfere with Wi-Fi network signals.

For example, cordless phones, Bluetooth devices, garage door openers, and microwave ovens can each take down a Wi-Fi network connection when powered on.

Solution: 

You can move your network equipment or (on home networks) change some Wi-Fi radio settings to avoid this problem.

Insufficient Wi-Fi Network Range and Power

Even without interference from other equipment, Wi-Fi connections can occasionally drop on devices located near the edge of the network's wireless signal range, or even when the device is too close to the router.

Solution:

Wi-Fi links generally become more unstable with distance. Relocating your computer or other gear is a simple, but not always practical solution.

Otherwise, consider antenna upgrades and other techniques to improve wireless signal transmission and reception

The Network Is Overloaded

Your hardware and home might be set up perfectly to accommodate Wi-Fi signals and avoid interference, but if there are too many devices using the network, the available bandwidth for each device is limited.

When each device lacks enough bandwidth, videos stop playing, websites won't open, and the device might even eventually disconnect and reconnect from the network, over and over, as it tries to hold on to enough bandwidth to keep using Wi-Fi.

Solution:

Take some of the devices off of the network. If your TV is streaming movies, turn it off. If someone is gaming on your network, have them take a break. If a few people are browsing Facebook on their phones, ask them to disable their Wi-Fi connection to free up some of that bandwidth... you get the idea.

If someone's downloading files on their computer, see if they can use a program that supports bandwidth control so that less bandwidth will be used for that device and more will be available for your Wi-Fi device.

Unknowingly Connecting to the Wrong Wi-Fi Network

If two neighboring locations run unsecured Wi-Fi networks with the same name (SSID), your devices may connect to the wrong network without your knowledge.

This can cause the interference and range problems described above. Additionally, in this scenario, your wireless devices will lose connection whenever the neighbor network is turned off, even if your preferred one remains functional.

Not only that but if the other network is suffering from bandwidth issues like described above, then your device might experience those symptoms too, even if their Wi-Fi remains on.

Solution:

Take proper security measures to ensure that your computers and other devices connect to the right network

Network Driver or Firmware Upgrade Required

Each computer connected to a Wi-Fi network utilizes a small piece of software called the device driver. Network routers contain related technology called firmware.

These pieces of software might become corrupted or obsolete over time and cause network drops and other wireless problems.

Solution:

Upgrade the router's firmware to the newest version to see if that fixes the network connection problems.

Also consider updating your device's driver, if that's supported on your particular device. For example, if your Windows computer keeps disconnecting from Wi-Fi, update the network drivers.

Incompatible Software Packages Installed

A Wi-Fi connection might fail on a computer if it has incompatible software installed.

This includes patches, services, and other software that modifies the networking capabilities of the operating system.

Solution:

Record each time you install or upgrade software on your computer, and be prepared to uninstall any incompatible software or reinstall a corrupted program.
