What to Do When Your WiFi Keeps Disconnecting
Although there are many reasons why your WiFi connection keeps disconnecting, you can solve most of them yourself. Before we get into more complex solutions, try some of these quick checks to immediately restore your WiFi and run it again.
- Check if your WiFi switch is on.
- Make sure you are using the correct WiFi connection.
- Make sure everything on the router is connected as it should.
- Check the router indicator lights for abnormalities or indicators other than green. You can use the router manual to understand the meaning of each indicator and how to solve any problems.
- Move your device closer to the router, especially where there is a lot of interference. You can also purchase a WiFi range extender to increase the strength of the WiFi signal.
- Connect the Ethernet cable to your device and check again that the connection is secure. If it works, the problem is with the wireless signal.
- Check with your ISP for any connection problems or service interruptions in your area.
Remove any electronic objects or devices that may interfere with the router.
- Change the router’s WiFi channel, especially if your network overlaps with nearby networks.
- Restart your computer, mobile device, or router to help reset network settings, and then try connecting to WiFi again.
- Check for pending updates on the computer and install them.
- Delete and read the wireless network.
- Temporarily disable your security software (antivirus software), as this may conflict with other software and cause problems with your WiFi connection.
- Update router firmware. If you are not sure how to do this, please consult your ISP.
- Run network diagnostics to resolve the problem. In Windows 10, right-click the WiFi icon on the taskbar and select Troubleshoot problems. On Mac, select Menu > System Preferences > Assist Me > Diagnostics and use the Network Diagnostics tool.
Update or Reinstall WiFi Adapter Driver
If your WiFi adapter driver has expired, your device will continue to disconnect from WiFi. You can update or reinstall the driver to solve the problem.
- Right-click Start > Device Manager and then select Network Adapters to expand the category.
- Next, right-click your WiFi adapter and select Update Driver.

Check Power Management Settings
Your computer’s power management settings may disable the wireless adapter and cause it to temporarily disconnect. You can make small adjustments to the parameters and solve the problem.
- Right-click Start > Device Manager and expand the Network Adapters section.
- Double-click your WiFi adapter’s name, select the Power Management tab and uncheck the Allow the computer to turn off this device to save power box. Restart your computer and check if the WiFi works again.
Check DHCP Settings
DHCP (Dynamic Host Configuration Protocol) automatically assigns IP addresses throughout the network so your devices can connect and communicate over the network. If there is a problem with DHCP, your WiFi will not work properly.
- In Windows 10, select Start > Settings > Network & Internet and then select Wifi.
- Select your connection and then check whether the IP assignment option under IP Settings says Automatic (DHCP). If it does, then DHCP is enabled, but if it doesn’t, select Edit > Automatic (DHCP) and then check if your WiFi is any better.
- On a Mac, select Menu > System Preferences > Network and ensure your network has a green dot next to it.
- Select Advanced > TCP/IP tab and check if the Configure IPv4 option is showing Using DHCP. If not, select the dropdown menu, choose the option and check whether your WiFi works again.
Resolve Dropped or Lost WiFi Connections
If your WiFi is still disconnected even after trying the steps in this guide, you can restore your computer or router to its original factory settings. During the factory reset, you will lose all settings and data, so be sure to back up all data on your computer.
After restarting the router, please take the time to reconfigure and check the WiFi connection. If all else fails, please contact your ISP for more guidance or to get WiFi without an Internet provider.
