Solution to WiFi drop-out on Windows 10 PC

  • by Michael Kearney

At some point (not sure what the trigger was), my PC started to drop its WiFi connection. This would happen several times a day and was very frustrating!

Right clicking on the wireless icon in the task bar (bottom right) and hitting Troubleshoot would temporarily fix it most of the time. Sometimes, I had to go into the device manager (windows key + x) and disable and re-enable the wireless network adapter to get it going again.

WiFi dropping out problem fixed.  Nervous breakdown averted :-)​
