Internet stopped working and you don't know why? One of the things you can do is unplug it router or your modem, wait for ten seconds and then reconnect it.
Your router is a computer
You might not think of it this way, but your router is a computer. Inside that plastic box is a CPU, a μνήμη and one space local storage. All of these work with an operating system. And just like with a computer, things can go wrong at some point. Maybe there's an error causing a memory leak, or maybe the CPU has overheated.
The simplest solution to these kinds of computer problems? Power off and on.
Restarting a computer can solve these kinds of problems. But why do you need to wait 10 seconds or more?
If you ever unplug a gadget you might see the indicator light modes stays on for a few seconds? There is a reason it happens and it is linked to our answer.
Most electronics use capacitors, which basically work like tiny batteries.
They don't store much energy, but sometimes they can have enough to keep a memory chip running for a few seconds. The 10 second wait ensures that each capacitor is fully discharged and thus each memory chip is erased. This will ensure that all the settings on your router will be reset to the way they were.
