Why did the Internet stop working through a Wi-Fi router?

 The router does not respond to the power connection

Sorry, but your router most likely died completely. Every router (well, almost every one) has activity indicators.

This is interesting: I gave my neighbor a Wi-Fi password, how can this threaten me? Is it safe to give a password to your Wi-Fi network?

And if these indenters do not light up when connecting the device to the outlet, then this is very bad.

What can be done?

Well, first check if there is a power off button on the router. This is the button on the TP-LINK TL-MR3220:

If the button is on, then you need to check the power supply, maybe it's in it. Usually, power supplies burn out more often than routers themselves. Perhaps the neighbors have the same router, run and ask for a couple of minutes.

If the device still does not work, then return it under warranty. And if there is no guarantee, then it is better to throw it out and buy a new one than to give it to a paid repair. Although, you can take it to the workshop, perhaps the repair will not be very expensive.

Why is this happening?

For many reasons. Perhaps a manufacturing defect, but most likely the router burned out due to an unstable voltage in the network, a thunderstorm, or moisture. If possible, connect the router through a voltage regulator. Well, or just turn it off when you see that there will be a thunderstorm.

This was the most difficult case, now we will consider lighter breakdowns.

Error diagnostics

In the event of emergency situations, many people wonder why there is no Internet after setting up the router. In reality, there can be many reasons, therefore, to identify it, it is necessary to carry out diagnostics.

How to connect and configure a D-Link Dir model 615 router

If, after setting up the router, the Internet does not work, then you definitely need to look for the culprit.

If the Internet disappeared abruptly, and before that everything worked, you need to perform the following measures:

Computer networks are the basis of communication in IT. They are used in a huge variety of ways and can include many different types of network.

First of all, you need to reboot the router and all devices connected to it. As practice shows, in most cases it helps.

Make sure the connection of the network cable to the router is not broken. Perhaps during the operation, something has moved away.

It may seem obvious, but such situations also occur. You need to make sure that the Internet is paid for, as well as that there are no problems on the part of the provider. In order not to guess, you need to call the round-the-clock technical support and find out everything.

If the above methods did not help, then you need to connect the network cable directly to the computer and check its performance. If there is no connection, then there is a 100% problem with the provider. If it works, then the reason lies in the router. It is recommended to perform a factory reset.
