You lot're Performing a Forced Reboot
Unplugging something usually works because many consumer-tech devices, like cable modems, routers, and streaming TV boxes, take tiny computers within them. Unplugging and plugging them dorsum in forces those computers to restart and clear any temporary software problems.
The internal computers in those devices run built-in software (called firmware) that controls the beliefs of the device. Sometimes, the firmware includes bugs that might lead to error states, retentivity leaks, or crashes.

It'due south a Temporary Ready

To do that, you lot'll take to download and perform a firmware update for that particular device.
Hardware faults in a device can besides cause problems that restarting might temporarily solve. Nonetheless, a permanent fix will crave a repair or replacement of the device. In these cases, it's all-time to consult the manufacturer's support department.
Devices that Often Benefit from the Unplug/Plug Back in Method
Generally, it's best to only unplug devices designed as consumer appliances that don't have On/Off switches. These devices load their software from firmware, which generally won't be corrupted from an abrupt ability bike.
A few examples are:
- Cablevision modems
- Internet routers

What if a Device Has a Power Switch?

Switching off a "soft" ability button and turning it on again on a faulty device won't necessarily strength an internal reckoner restart. So, you might nonetheless have to motion on to the next step: unplugging the device and plugging information technology back in.
When Y'all Shouldn't Unplug a Malfunctioning Device

Sometimes, though, a computer becomes completely unresponsive and in that location's no way to fix it within the software. In these cases, it's okay to pull the ability cord, and then restart the machine equally a last resort. There might exist some data loss, but, sometimes, y'all just accept no other choice.
There are also sure types of sensitive scientific and medical equipment that should never all of a sudden be unplugged. Doing so could crusade damage or put someone's life at risk.
Manifestly, you lot want to brand sure any device you're about to unplug won't put anyone's prophylactic at take chances while it goes offline and powers dorsum on.
