What does los mean on a router. The red internet light on the router is on. As practice shows, there are two main reasons

Readers often turn to me for help and advice in setting up WiFi, and one of the popular questions is what does it mean if there is no Internet and at the same time the router is lit with an orange light opposite the WAN icon? On TP-Link routers, the orange indicator is additionally made in the form of a highlighted icon-symbol of the Internet connection, which means that the problem is with it.

Possible Causes of the Orange WAN Light On

In earlier models, the LED could also be green, but when a connection break occurs, it does not stay on all the time, but blinks.


The solution to the problem discussed in this article will only apply to the case when the router lights up orange (or red, or blinks) after inserting the cable from the provider into - normally it should be constantly lit green, which indicates that there is no connection to the Internet. If the router, after connecting the cable, does not light any “lights” at all, then this is a completely different problem.

So, there can be several reasons for the lack of connection.

Let's take a look at each of them in detail. We cannot influence the first one in any way - breakdowns in the provider's equipment, or line breaks occur regularly even with the most stable Internet service providers. Therefore, in case you did nothing, and the orange light on the router itself turned on, the first thing I recommend is calling the support service and finding out if there are any breakdowns or if they are doing technical work.

Orange indicator due to incorrect settings of the TP Link router

The second reason is that the configurations for connecting the TP Link router to the Internet have gone astray. In general, when you first turn on the orange indicator is on until you insert the cable into the WAN port and enter all the settings for connecting to the Internet. If you didn’t know, then after installing the router, the Internet will not work by itself (unless the type of connection to your provider is dynamic IP) - for it you need to enter the data that is specified in the service agreement. After they are entered correctly, the color changes to green.

Orange signal on the router due to binding by MAC address

If this did not happen, but you are sure that you did everything right, then there is such an option that the provider binds the MAC address of the computer to your account. That is, you bought a new router, and now, instead of the network card of the computer, another device “communicates” with the equipment of the service provider, which has a different physical (MAC) address. More responsible providers report this to users - for example, when I change the router, when I try to open any site, a message appears that I need to restart it for a new binding.

There are two options for solving the problem:

  • Call support and say that your computer has changed
  • Make the PC the built-in tools of the router.

The second option is preferable. I describe in detail how to do this in separate articles for each manufacturer - select your company from the menu of our website and read.

The orange light is on due to a program failure or a broken WAN port

If the orange indicator suddenly lights up - yesterday the Internet worked, but today it doesn’t, and at the same time the provider says that everything is OK with him, then you need to think why this happened. The first thing that comes to mind is that due to a power surge, all the settings on the router went wrong. For the future, to avoid this, connect it only through a voltage stabilizer.

In order to return everything to its original state, the easiest way is to use the “Reset” button on the router case. Then go back to the admin panel using the login and password indicated on the label on the bottom of the router case, and set everything up again.


Finally, no one excludes breakdowns inside the WAN connector or on the router chip. Here are my thoughts on fixing the problem of a burning orange indicator on the router - I didn’t seem to miss anything, but if you have something to add, then write in the comments, we will figure it out together.

Errors when configuring a Sagemcom router [email protected] 2804

Theoretically, setting up a Sagemcom router [email protected] 2804, v7 from Rostelecom, is no problem. Immediately after receiving the router for rent (a couple of years ago), I connected the device to the computer, inserted the supplied disk with software (Settings Wizard program) into the drive, and after a few minutes the Internet was already working. A couple of days ago, it was necessary to configure the same router for another subscriber, but the configuration from the disk ended with the red “light bulb” lit up. Those. the Internet LED indicator (with the @ symbol for a dog) signaled that there was no Internet connection.

The red “light” with the @ sign is on on the router - Internet is not available

As a rule, this indicates that incorrect settings have been entered. Since the setup was carried out from the disk, I could make a mistake only when entering the login and password, but the catch is that they were previously “driven” into Notepad and I simply copied and pasted them, i.e. the error has been removed. I reset the settings to the factory settings several times and tried to configure the router again using the supplied disk, the result did not change.

As a reference, I remind you that you can reset the router to factory settings using the Reset button. To get to it, use a paper clip or a toothpick.

Customization Error Messages

During the "dancing with a tambourine" various errors occurred, which are presented below in the screenshots.

“The wizard did not find the router” - this indicates that the setup program does not “see” the router at all

"The router is not available" - the message appeared at the stage of setting up Wi-Fi. Simply put, the computer "lost" the router again

I tried to enter the settings through the web interface (IP 192.168.1.1 , login and password admin), but I couldn't. I noticed that you can log in through the web interface without any problems if the settings are reset to factory settings. I read on the Internet that the LAN cable should be connected to the second connector and use the IE (Internet Explorer) browser. Alas, the trick also failed.

It is not possible to get to the web interface of the router, although the IP address is typed correctly - 192.168.1.1

Where did the dog dig?

After trying unsuccessfully to turn a red dog into a green one, I erroneously concluded that the router had failed. I contacted Rostelecom technical support (free technical support phone 8 800 100 08 00) and left a request. The next morning I waited for a call and found out the key information - when configuring the router, the network cable must be connected to port number 3, not #2, as stated in the online source.

When configuring the router, the network cable must be connected to the LAN3 connector - on the Sagemcom 2804 router in a white case, it is marked in green

After connecting the cable to the correct connector, I managed to enter the Sagemcom settings [email protected] 2804 through the web interface and understand the reason why the "dog" icon was red after trying to configure from the disk. It turned out that the information about the login and password was not saved from the disk after setup - the corresponding fields are empty!

After entering the login and password, the Internet started working.

The "dog" icon turned green - the Internet is working! Pay attention to the icon for connecting to the Ethernet port - the number “3” is glowing next to it, indicating that the cable is connected to LAN3

Is everything so simple?

As my further excrement showed, the setup using the Setup Wizard may fail even if the network cable is connected to the LAN3 connector.

As I understand it, the errors “Presence of a PPPoE connection” and “Connection to the Rostelecom server” indicate that the login / password pair was entered incorrectly, although I again copied the data from Notepad. As you probably guessed, the login and password were not saved again in the router settings.

There are two ways to solve the problem:

  1. Go to the settings through the web interface and add a username and password;
  2. Restart the router setup from the disk.

Was it possible to do without an extra headache?

It often happens that we pick up the instructions only after we break something 🙂 If you take the paper instructions for the Sagemcom router [email protected] 2804, v7, it does not say anything about the need to connect a network cable to the LAN3 connector. However, this is clearly indicated when using the Setup Wizard, which is installed from the CD.

To be honest, I didn’t pay attention to this nuance at all, perhaps due to the fact that earlier, for which the port number is not critical. In general, I wonder how the LAN3 port on the Sagemcom 2804 differs from the others?

conclusions

  1. When setting up a Sagemcom Universal Router [email protected] 2804, v7 from Rostelecom, connect the network cable to the LAN3 port (marked in green).
  2. In order not to suffer with setting up the router via the web interface, use the Setup Wizard from the supplied CD. If you don't have a CD, download the Setup Wizard from the official Sagemcom website (the smart software is called "Auto Configuration and Firmware Update/Repair Program", in short the setup program).
  3. Sometimes you should read the instructions - in many cases this will save you an extra headache.
  4. Learn from the mistakes of others, especially ours. To do this, do not forget to bookmark the site 🙂

This is due to the requirements of new services and "heavy" applications that can fully function only with a PON connection from Rostelecom. That is why it was necessary to introduce fiber optic technologies that meet the requirements of high-speed Internet.

This article contains several items:

  • What is PON technology
  • Features of PON Internet
  • Connection equipment
  • Setting up modems

PON technology from Rostelecom

The most important advantage of this technology compared to other types of connection is the high data transfer and, as a result, the responsiveness of networks. Therefore, a PON connection is optimal for connecting large co-companies to the Internet.

Currently, Internet speed requirements reach 100 Mbps, and will approach 1 Gbps in the near future. Only optical cables can support such high performance. This is especially true for large distances, which, of course, exist between the provider and the user.

For service providers, FTTH (Fiber to the Home) bandwidth is already available, which is routed to the home. Thus, new buildings will serve as the basis of access networks and will be able to function for many years. The implementation of FTTH access networks is far from being a cheap process, which requires not only labor-intensive construction work, but also significant financial costs.

However, the development of wavelength division technology (WDM), which uses a single fiber for incoming and outgoing traffic, has greatly improved the situation. The first of the FTTH networks have already moved to a newer standard, where a single fiber is connected to a passive optical splitter, which in turn distributes the signal to several subscribers.

It was this standard that began to be called the PON technology, which Rostelecom is now actively using. With this technology, the network can support 1:64 signal splitting from a single fiber. In addition, Rostelecom's PON technologies allow subscribers to use without the use of IP set-top boxes.

Advantages of the Internet using PON technology from Rostelecom

The most significant advantage of PON Internet from Rostelecom is that with the help of inexpensive optical splitters, a common fiber provides a network for many users. But it should be remembered that such splitters maintain network responsiveness with up to 64 users. Thus, this technology is of interest not only to subscribers, but also to service providers who want to replace somewhat outdated copper networks.


Features of PON networks, which can also be called pluses, are:

  • absence of electromagnetic interference, since there is no need to use active equipment directly in the access network;
  • reduction of fiber and equipment in the central office.

Rostelecom's PON equipment provides greater throughput and supports dual distribution ratio. This means that with a 64-lane allocation, each user will get a fairly large connection bandwidth, about 35 Mbps. If the provider uses lower distribution factors, for example, 16 or 32, subscribers will receive even more bandwidth. Due to the efficient use of the bandwidth of the PON standard, subscribers are provided with a high data transfer rate. In addition, this technology makes it possible to use not only high-speed Internet, but also multi-service services such as video, voice, data.

Which modems are suitable for connecting PON from Rostelecom

GPON technology is an industry-wide interchangeable standard. This indicates that PON modems of any manufacturer will work correctly with devices such as ONT.


This, in turn, affects the reduction in the cost of equipment and enables providers to offer subscribers the most favorable tariffs for services. Also, it is important to note that the updated technology based on XGPON standards increases network performance up to 10 Gbps, while maintaining backward compatibility with already deployed networks.

How to set up the equipment

As a rule, PON equipment from Rostelecom does not need to be carefully configured, since all the necessary parameters have already been entered by the provider. But in some Wi-Fi router models with PON technology, you will need to configure the wireless network and set connection parameters. These parameters include the login and password of a PPPoE user type, which Rostelecom provides to the subscriber when concluding an agreement.


If, after correctly entering all the necessary parameters, the PON indicator on the equipment lights up red, we recommend that you contact Rostelecom customer technical support with this problem.

If you have any questions about this technology, we recommend watching this video.

If a red light is on on the Rostelecom router, you definitely won’t be able to use the device, since such a signal clearly indicates a connection problem. To restore the connection and return access to your favorite sites, you need to understand the reasons for what is happening. After all, without finding the source of trouble, the user will not be able to decide what to do. At the same time, the fight against difficulties will not cause huge difficulties and will not take much time, since the list of possible causes that caused equipment failures is extremely short. Therefore, it is enough for subscribers to stock up on attentiveness, accuracy and patience, after which they can proceed to troubleshooting and restoring access to the network.

Why is red on the Rostelecom router

There are several reasons why the indicator is lit red:

  • equipment failure;
  • incorrectly set device parameters;
  • loose or loose cable;
  • lack of funds on the account and the subscription fee for connection not paid by the client;
  • technical work or network repair by the provider.

In addition, the appearance of an unusual signal leads to a banal equipment breakdown or a broken cable. But this is much less common, and subscribers will not be able to cope with such serious troubles on their own. Therefore, the only way to solve the problem in such situations will be to contact the service center and transfer the equipment for repair.

Why is it not lit (@)

When faced with a problem for the first time and notice that the dog (@) icon is not lit, users should use the easiest way to solve problems. They should just turn off the equipment and leave it for a couple of minutes, then turn on the device again. Such actions will allow you to restore the operation of the device after a possible failure.

It is important to emphasize that the described approach will not help if the reason that the red “dog” light is on on the Rostelecom router is due to more serious errors and malfunctions. But this does not mean that the described method is bad. Its main advantage is simplicity and the ability to save time if the proposed solution proves to be effective.

Internet cable not connected

The next step that can help restore the Internet connection is to check the cable. Subscribers will have to look at how securely and firmly the wires to the router are hooked up. Poor cable contact with the device is one of the most common reasons for a lack of communication. In this case, the user may not be aware that the contacts have moved away, since sometimes one awkward, careless movement leads to problems.

It is important to add that in situations where the red power light is on on the Rostelecom router, it is worth checking the reliability of connecting the power supply to the device or trying to insert it into another outlet.

Technical work on the provider's side

Sometimes the light does not flash green due to the actions of the service company. You can find out about the technical work:

  • on the official portal of the provider;
  • in the client's personal account;
  • by calling the contact center and asking questions of interest to support operators;
  • by contacting consultants in another convenient way for the client;
  • visiting the nearest office and talking about the difficulties with the manager working there.

It is worth emphasizing that a call is the most convenient, since it allows you to get accurate, verified information without wasting time standing in line and independently searching for the necessary information.

Connection errors

The next reason that can lead to connection difficulties is the incorrect configuration of the router.

To correct the situation, you will need:

  1. turn on the set-top box and connect to the network through a computer or laptop (lack of connection will prevent access to the Internet, but will not interfere with the connection);
  2. open a browser and enter the combination 192.168.1.1 in the address bar (the exact address is indicated on the device case);
  3. log in to the system (usually the admin/admin pair is used);
  4. open the network settings section;
  5. change the parameters by following the instructions or by contacting support operators to clarify the required values;
  6. save status changes.

After that, it remains to check the result and make sure that the malfunctions are in the past.

Forgot to pay internet

Situations when subscribers forget to replenish their account deserve special mention. You can check the balance and make sure that you have enough money in your personal account. To log in to the official portal, it is enough to know the username and password from the account.

An alternative way to obtain information will be a universal call to the hotline. Such a solution is convenient due to its own availability, since to use it it is enough to have a telephone at hand and know the number of the contact center.

The solution to the described problem will be to replenish the balance with the required amount.

What indicators should be lit on the router

For a simpler understanding of the reasons for what is happening, users need to understand the meaning of the indicators. The following bulbs are usually present on the body of the device:

  • Power - power indicator that lights up when the device is turned on;
  • Status - indicates the correctness of the system settings;
  • Internet (@, WAN) - indicates a connection to the network and the appearance of incoming traffic;
  • LAN (1, 2, 3, 4) - responsible for connecting a computer or laptop via cable;
  • WLAN - responsible for the distribution of traffic via Wi-Fi;
  • DSL - shows the status of the connection with the provider (blinks - in the process of connection, green - the contact is established).

The number of lights that should light up at the same time depends on the user's activity and the connection method chosen by him.

How to fix the problem

The last method of dealing with troubles, if a red light is on on the Rostelecom Internet router, will be a call to the contact center. The consultants will listen to the client who has contacted them and suggest what to do, or, if it is not possible to cope with the problem remotely, they will accept an application for a visit from the master.

But callers should prepare for the fact that operators may ask:

  • passport data;
  • contract number;
  • the exact connection address.

The listed information is required to identify the person who applied for help and ensure the safety of personal data.
