    What to Do When Your WiFi Keeps Disconnecting

    While there are varying reasons why your WiFi connection keeps dropping, you can troubleshoot most of them yourself. Before we go into more complex solutions, try some of these quick checks to get your WiFi back up and running again in no time.

    Quick Checks

    • Check whether your WiFi switch is set to On.
    • Ensure that you’re using the correct WiFi connection.
    • Make sure everything on your router is plugged in the way it should be.
    • Check the lights on your router to see if any seem unusual or other than green. You can use your router manual to know what each light means and how to resolve any problems.
    • Move your device closer to the router especially where there’s lots of interference.  You can also get a WiFi range extender to boost your WiFi signal’s strength.
    • Plug an Ethernet cable into your device and check if the connection is strong again. If it works, the issue is with the wireless signal.
    • Check with your ISP whether there are any connection issues or service outages in your area.
    • Remove any objects or electronics that could be interfering with your router.

    • Change your router’s WiFi channel especially if your network tends to overlap with nearby networks.
    • Restart your computer, mobile device or router to help reset the network settings and then try connecting to WiFi again.
    • Check for any pending updates on your computer and install them.
    • Remove and re-add the wireless network.
    • Temporarily disable your security software (antivirus) as this could be conflicting with other software causing issues with your WiFi connection.
    • Update your router’s firmware. If you’re not sure how to do this, check with your ISP.
    • Run a network diagnostic to troubleshoot 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.

    1. Right-click Start > Device Manager and expand the Network Adapters section.

    Check DHCP Settings

    DHCP (Dynamic Host Configuration Protocol) automatically distributes IP addresses across the network so that your devices can connect and communicate over the web. If there’s a problem with the DHCP, your WiFi won’t work properly.

    1. In Windows 10, select Start > Settings > Network & Internet and then select Wifi.

    1. 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. 
    2. On a Mac, select Menu > System Preferences > Network and ensure your network has a green dot next to it.

    Resolve Dropped or Lost WiFi Connections

    If your WiFi is still disconnecting even after trying the steps in this guide, you can factory reset your computer or your router to return them to out-of-the-box factory settings. You’ll lose all your settings and data during a factory reset so make sure you backup any data on your computer.

    Once you reset your router, give it time to set itself up and check your WiFi connection again. If all else fails, contact your ISP for more guided assistance or get WiFi without an internet provider.
