A modem, like any other small and large equipment, is a rather complicated system. Therefore, the appearance of errors and malfunctions cannot be avoided. Sooner or later some unpleasant situation will happen. For example, one of the problems when connecting to the Internet: the light on the modem is off.
Next, we will consider ways to resolve the situation, as well as the most common errors that occur during operation of the device.
Before checking
If suddenly the Internet connection is lost, and the light on the modem lights up without interruptions, try checking the connection speed. This can be done using the SpeedTest program. It can be downloaded from the Microsoft Store or you can check it in your browser.
Why could this happen?
Quite often, a non-flashing light error appears due to some malfunctions or irregularities in the process. We will understand why the Internet light on the modem does not light up. This may be due to the fact that:
- the splitter has stopped working;
- the telephone cable is not connected to the hardware device correctly, and therefore such malfunctions occur;
- the equipment itself is not working properly;
- on the PBX line, interference or disconnection is observed;
- the subscriber was not connected to the PBX network.
Now we will understand why the Internet light on the modem is off and the Internet itself is not.
Restart
Quite often, users panic when network outages begin. The first thing that comes to mind is to call the provider and find out why. But not always the fault for the lack of connection to the global network lies with those who provide access to communications. To begin with, it is worth checking whether the red Internet light on the Rostelecom modem or another provider is on or off. If no signals are received, then perform the following algorithm:
- turn off the device and unplug the plug;
- wait from 15 seconds to five minutes;
- after that connect the modem back to the network and press the start button;
- wait until it boots, then check if the red Internet light on the Rostelecom modem or another provider is on.
In the event that the light signal does not interrupt, the connection is established. If it blinks, it means that the router searches for the network and tries to connect to it. This process can take about three minutes.
Most often, the action should solve the problem that the Internet does not light up on the modem.
Damage check
It may also happen that the absence of a light signal on the modem may result from mechanical damage to the cord or the device itself. To verify this, do this:
- turn off the modem and disconnect it from the network;
- Check the cord going to the outlet. Look for signs of a break in the coating, broken wires or signs of kink;
- if they are missing, check the cord that goes to the computer, inspect it for the same damage as mentioned above;
- Now check the modem itself - carefully inspect the case and antenna, make sure it is connected securely;
- try connecting all the wires to the connectors, make sure that they are installed firmly.
Another option is to check the light bulb itself. In the event that a network connection is present, but the signals do not go, then the indicator itself has failed.
Computer shutdown
If the modem has a red light on and there is no Internet, then you should pay attention to the settings for connecting to the network. In order to check whether the computer is connected to the global web, you must perform the following steps:
- through the Start menu, open the Windows settings program;
- go to the "Network and Internet" section there;
- you will see a window of parameters and network status;
- Scrolling to the bottom, among the subsections, on the right side, find the line of the Network Control Center, open this paragraph;
- There will be a transition to the standard application, where all available connections will be displayed, as well as the status of the current connection.
You can also try in another way:
- run the program "This computer" through the Start menu;
- in the left part of the window that opens, find the tab called "Network";
- by right-clicking on the displayed device, check the Internet connection (if it is disconnected, turn it on).
In the event that all of the above did not help and the Internet light on the modem does not light, try one of the following methods.
Driver update
Quite often, outdated network card drivers or the router itself may become the cause of problems with the modem. To check if there are updates available, you should do the following:
- in the Windows search bar, enter the phrase "Task Manager";
- You will be prompted to open a standard application - run it;
- among the list of devices, find the paragraph with network adapters;
- expand it and, right-clicking on each item, check in the context menu the need for driver updates.
This should fix the situation if the Internet light on the modem does not light.
What to do if only the power signal is on?
Sometimes it may happen that only the power connection indicator will work on the router, and there is no Internet connection. In such a situation, it is worth trying the following steps:
- the first is to disconnect and reconnect the modem to a power outlet (sometimes this action can correct the situation);
- if the restart does not help, then reset the device to factory settings (instructions for this action can be found in the manual for the modem itself or on the manufacturer’s website for a specific model).
Additional troubleshooting options
In the event that none of the above methods has corrected the situation, then it is worth trying the following steps:
- If you have such an opportunity, replace the modem power adapter.
- If resetting and updating drivers does not help, use the help of specialists in service centers. If the device is still under warranty and you have not made any interference with its operation, you can try returning it to the store.
- Well, the most commonplace option. If you have a fairly old device with an expired warranty, just replace it with a new modem.
