Is anyone else having the same problem? Maybe the problem is somewhere beyond your computer. Or maybe someone had the same issue and knows a quick fix.
Is everything plugged in? Could any of the cords have been pulled or disconnected? Push on each end to be sure it’s fully plugged in.
Check the power source. Could the power strip be turned off or overloaded? Try plugging a different device in and see if it works. Maybe the power strip has reached end of life.
Cycle the power. Shut down and restart your device. Turn off, then on, printers and other devices. When turning off, wait a few seconds before turning back on. For devices, without an on/off switch, just unplug the power cord. If it is a computer always shut down properly before unplugging!
If a problem with a wireless connection, check that wireless is enabled on your device. Laptops usually have a button or Fn key to enable/disable wireless.
