1. Change Home Network from Public to Private

Setting the profile type of your home network to private can make your connection more reliable. Follow these steps to change the network profile:

  1. Open the Action Center, and click the “Manage Wi-Fi connections”
    button next to the Wi-Fi icon.
Clicking the "Manage Wi-Fi Connections" tab next to Wi-Fi.
  1. Click the “Properties” icon in the upper-right corner of your current network.
Clicking the network Properties icon under Wi-Fi.
  1. The Settings app will open to show options for this particular network. Under “Network profile type,” change the marked option from “Public network (Recommended)” to “Private network.”
Clicking the "Private network" option under "Network profile type."

Note: it’s not recommended to do this when you’re using a publicly accessible network (e.g., in coffee shops, libraries, etc.), as you’d be opening the door to malware infection or hacking.

2. Turn Off Automatic Connection

This feature may be causing your Wi-Fi connection to switch between networks because of your proximity to a Wi-Fi signal. In turn, you may experience an intermittent Internet connection. Here’s how to turn it off:

  1. Go to the Action Center, and click “Manage Wi-Fi connections” as shown above.
  2. Click the “Properties” icon for your current network.
  3. Uncheck the “Connect automatically when in range” option.
Unticking the "Connect automatically when in range" checkbox in "Network & internet."
  1. In older versions of Windows 10, this might be known as Wi-Fi Sense. To access it, go to “Settings -> Network & Internet -> Wi-Fi (from the side panel) -> Manage Wi-Fi Settings -> Wi-Fi Sense.” Toggle off the option to “Connect to networks shared by contacts.”

3. Configure Power Management Options

Your wireless adapter may be affected by the power-saving features in Windows. Below are the steps to modify your power management settings:

  1. Press Win + X, then choose “Device Manager” from the list.
Clicking the Device Manager option from WinX menu.
  1. Locate “Network Adapters,” and click the arrow beside it. 
Clicking on "Network Adapters" under Device Manager.
  1. Select your wireless adapter from the expanded menu, and double-click it.
  2. Go to the “Power Management” tab in the new window, toggle off the option for “Allow the computer to turn off this device to save power,” and click “OK.”
Enabling the "Allow the computer to turn off this device to save power" checkbox under Power Management
  1. Make sure that all changes are applied by restarting your Windows PC.

4. Use the Network and Internet Troubleshooter

Windows features a built-in network troubleshooter. It may help determine and resolve the underlying issues that make your Wi-Fi disconnect all of a sudden. Follow these steps to use the Network Troubleshooter on Windows:

  1. Open the Settings app.
  2. Go to “System -> Troubleshoot.”
Clicking the Troubleshoot option in Settings app.
  1. Select “Other troubleshooters.”
Clicking the "Other troubleshooters"option in Settings app.
  1. Find the “Network and Internet” troubleshooter, and click “Run.”
Clicking on "Network and internet" troubleshooter.
  1. In Windows 10, go to “Settings -> Network & Internet -> Status.” Under “Change your network settings,” select Network troubleshooter.

Tip: sometimes even the Windows troubleshooter needs troubleshooting. Learn how to get started with that.

5. Check Whether the Device Connection Limit Has Been Reached

Your Wi-Fi’s bandwidth isn’t unlimited: the more devices connected, the slower your connection gets. When the number of devices connected reaches the limit, your Wi-Fi may disconnect from some devices, including your Windows device.

The fix for this is very simple: just change your Wi-Fi password. This automatically disconnects everyone from your network, allowing you to connect your devices again.

While the steps vary depending on your provider, this example shows a Wi-Fi password change on a ZTE modem:

  1. Navigate to 192.168.1.1 in your web browser.
  2. Log in using your credentials.

  1. Go to “Network -> WLAN -> Security.”
  2. Change the password written in the “WPA Passphrase,” and click “Submit.”

  1. You will automatically be disconnected from the network.
  1. Reconnect using your new password.

6. Fix a Bad Wi-Fi Signal

The sudden disconnections happening on your device may be caused by it not sufficiently detecting your Wi-Fi signals. It may do this because:

  • Your workstation is too far from your Wi-Fi router.
  • There are reflective obstacles between your device and your router, such as glass and metal.
  • You placed your router behind an area made of stone and tile, making its signals unable to pass through easily.
  • There are electronic devices (e.g., baby monitors, microwaves, etc.) near your Wi-Fi router that interfere with its signals.

In this case, changing the position of your router may be the first thing you want to try. Consider using the Wi-Fi signal meter on your device to check areas with poor connections. On a Windows PC, view the Wi-Fi networks in the Access Center to know when the signal is stronger.

You can also try moving your workstation closer to your connection and removing obstacles between it and your Windows computer.

FYI: check and understand the differences in this guide on Wi-Fi 5 vs. Wi-Fi 6 vs. Wi-Fi 6E.

7. Reset Wi-Fi Autoconfig Service

The WLAN AutoConfig service is a Windows service that automatically configures your computer’s wireless network adapter. It may be disabled, causing your Wi-Fi disconnection issues. Follow these steps to reset it:

  1. Press Win + R to open the Run window.
  2. Type services.msc, and click “OK.”
Opening the Services app via Run utility.
  1. Right-click “WLAN AutoConfig” in the Services window, and choose “Properties.”
Showing WLAN AutoConfig properties in Services app.
  1. Select “Automatic” in the “Startup type” drop-down, and click “Apply.”
Seting automatic startup type for WLAN AutoConfig.
  1. Restart your computer to ensure that all changes are applied, then close the window, and check your Wi-Fi.

8. Check Your Internet Plan

Your device may not have disconnected from your Wi-Fi; it may just be too slow to load. This usually happens when you’re trying to consume more than the bandwidth limits of your Internet plan will allow, or there are too many people using your Wi-Fi.

The best way to curb this issue is to get an upgrade. If it’s not within your current budget, try avoiding bandwidth-heavy usage, such as downloading a movie or streaming in 4K. You can also try removing people from your network.

Tip: always ensure that you create a backup of your registry before applying any tweaks.
