Basic Troubleshooting for Loss of Internet Access

Step 1: Hardware

  • Confirm all network wires are still plugged in and in good condition, including all wires for Modem/Router/Access Point and possible Ethernet connections coming from the router to the computer.
  • Check your laptop for a hardware switch that toggles the WiFi on/off, similarly, some laptops have a keyboard key for that, it may look like an antenna on the top row.
  • Check to see if any other devices on your network have lost their connection to the internet.
  • If you have no internet connection on multiple devices, your internet might be down.
  • Restart your Computer and unplug your router for 30 seconds then power it back up.

If you determine that more than one device is unable to connect to the internet, there’s likely an issue with your service provider or Router/Modem/AccessPoint.

If only a single device has lost connection continue to step 2 for Windows instructions.

Step 2:  Software

After each major bullet point check to see if your connection has been restored.

  • Check to make sure WiFi is enabled and airplane mode is disabled.
  • Open Settings Network & Internet and run the Network Troubleshooter
  • Select Start button, type Command prompt, right-click Command prompt, and then select Run as administratorYes.
    • At the command prompt, run the following commands in the listed order.
      • Type netsh winsock reset and press Enter.
      • Type netsh int ip reset and press Enter.
      • Type ipconfig /release and press Enter.
      • Type ipconfig /renew and press Enter.
      • Type ipconfig /flushdns and press Enter.
  • Select Start button, type Device Manager, select Device Manager from the list of results.
    • In Device Manager, select Network adapters > the network adapter name.
    • Right-click the network adapter, and then select Update driver > Search automatically for updated driver software. Then click Close.
    • If it installed an updated driver, select the Start button Power  > Restart and see if that fixes the connection issue.
  • Go back to Device Manager again select Network adapters > the network adapter name.
    • Right-click network adapter, and then select Uninstall device > Don’t delete the driver unless you made a backup prior.
    • After uninstalling the driver, select the Start button Power  > Restart. Windows should reinstall the driver automatically upon restart.

Hopefully, by this step your connection has been restored, if it hasn’t there may be an issue with your wireless card adapter or Ethernet port/cord.
