Wi-Fi Keeps Disconnecting

Overview

Wi‑Fi that disconnects repeatedly can be caused by weak signal, router issues, driver problems, interference, or incorrect network settings. This guide walks through the most common causes and how to fix them.

Common symptoms

  • Wi‑Fi drops randomly
  • Connection disconnects when moving around the home
  • Wi‑Fi disconnects but reconnects automatically
  • Other devices stay connected while one device drops
  • Streaming or downloads stop unexpectedly

Possible causes

  • Weak Wi‑Fi signal
  • Router firmware issues
  • Outdated Wi‑Fi drivers
  • Interference from other devices
  • Power-saving settings disabling Wi‑Fi
  • Incorrect network configuration

Step 1 – Restart your router

  1. Unplug the router and modem.
  2. Wait 30 seconds.
  3. Plug the modem back in and wait for it to fully start.
  4. Plug the router back in and wait for it to fully start.

Step 2 – Move closer to the router

Weak signal is one of the most common causes of Wi‑Fi drops. Test the connection near the router to confirm.

Step 3 – Forget and reconnect to the network

  1. Open Settings > Network & Internet.
  2. Select Wi‑Fi.
  3. Choose your network and select Forget.
  4. Reconnect and enter your password.

Step 4 – Update Wi‑Fi drivers

  1. Right‑click the Start button and select Device Manager.
  2. Expand Network adapters.
  3. Right‑click your Wi‑Fi adapter.
  4. Select Update driver.

Step 5 – Disable Wi‑Fi power-saving mode

  1. Open Device Manager.
  2. Right‑click your Wi‑Fi adapter and select Properties.
  3. Go to the Power Management tab.
  4. Uncheck Allow the computer to turn off this device to save power.

Step 6 – Change Wi‑Fi frequency band

If your router supports both 2.4 GHz and 5 GHz, try switching bands:

  • 2.4 GHz = longer range, slower speeds
  • 5 GHz = faster speeds, shorter range

Step 7 – Reduce interference

Devices that can interfere with Wi‑Fi include:

  • Microwaves
  • Bluetooth devices
  • Wireless cameras
  • Baby monitors

Step 8 – Reset network settings

  1. Open Settings.
  2. Go to Network & Internet.
  3. Select Advanced network settings.
  4. Choose Network reset.

Step 9 – Update router firmware

Log into your router’s admin page and check for firmware updates. Outdated firmware can cause frequent disconnects.

Step 10 – Test another device

If only one device disconnects, the issue is likely with that device. If all devices disconnect, the router or ISP may be the cause.

When to contact your ISP

  • Frequent disconnects on all devices
  • Router restarts randomly
  • Wi‑Fi drops during peak hours
  • Speed tests show unstable results
