The router turns off wifi after a while. Should I turn off my WiFi router at night?

26.09.2019

Many experts call wi-fi the “silent enemy.” Their main argument in defense of this point of view is based on the fact that the wi-fi router produces radiation.

New technologies have changed the world and expanded our options for communication, work, entertainment and almost any thing we can imagine. In particular, it plays a very important role in our lives. wireless internet, which gives us access to many useful tools. Wi-fi has become an indispensable thing in our homes, at work, in educational institutions and other places where it is important to maintain contact with the outside world. Unfortunately, wireless internet has some disadvantages that most people are not aware of. In particular, it can negatively affect our health.

Why can Wi-Fi Internet technology be dangerous?

Although the means mass media report the dangers of radiation from cell phones and other electronic devices, many people ignore these warnings or are still not sufficiently aware.

This technology has been used by humans for several decades, but it actually takes much longer to understand how it affects the human body.

There have already been several scientific research, which analyzed the influence electromagnetic waves on brain activity and our life support system. There is reason to believe that wireless Internet and radiation from it can cause cancer and other serious diseases.

A public-domain report known as Bioinitiative claims that nearly 2,000 international studies have found a link between long-term exposure electromagnetic radiation on the body and the formation of tumors.

In addition, this radiation can cause ongoing headaches, migraines, hyperactivity and sleep disturbances.

People who work with this type of equipment must strictly follow the recommendation to reduce the impact of the negative effects of radiation on the body.

Concern is heightened by the impact of Wi-Fi signals on children, whose bodies are especially susceptible to damage as they are in the process of development.

With this in mind, countries such as the UK, France and Sweden have begun removing wi-fi routers from schools, museums, libraries and other public areas to reduce the impact of this technology on children's health.

How can you reduce the negative effect of using a wi-fi router?

To reduce the negative effect of a wi-fi router, you can do the following:

Turn off the router at night or when no one is using it.
If the router is in the kitchen or bedroom, try moving it to a less frequented location.
Think about installing a cable network, even a telephone network. Wireless mobile internet much more comfortable, but the effect of radiation causes a lot of harm to our health.
Use mobile phones and computers only at certain times. Don't keep them in your room.
Spend more time on fresh air, do it physical exercise and read books on paper, not in digital format.

Unfortunately, it is not yet possible to know for sure when we are exposed to radiation. In addition, electromagnetic pollution in the world is increasing by leaps and bounds, and we still do not know what its levels will be in a few years. In countries such as the United States and Japan, scientists are already trying to develop another type of technology that does not involve the use of electromagnetic waves. According to preliminary estimates, it took about 30 years to warn people about the impact these devices have on the human body.

Each of us can reduce the impact of harmful technologies on our bodies and the bodies of loved ones. We must be responsible and careful users of new technologies for our own safety. Remember that although wireless Internet is very convenient, it can be dangerous to our health. Find a balance! published

Very often, when connecting to the World Wide Web via local network Users are faced with the fact that the Internet through the router periodically disappears. After rebooting the device, the Internet connection usually appears, but this does not solve the problem. And the router has to be restarted every 5 minutes.

And here we will look at the main reasons why the Internet connection through a router drops out so often, as well as what needs to be done if interruptions in the Internet connection occur.

Why does the Internet keep dropping out?

1.The most relevant periodic “disappearance” of the Internet is when the router distributes a connection to the World Wide Web to several devices simultaneously.

In most cases, this is due to the technical capabilities of the router: the router simply cannot cope with the network load placed on it.

Let's look at why the Internet constantly disappears through a router using a specific example.
Let’s say the Internet is distributed by a router to 3 computers at once:

- on the first, the user watches the movie online;
- on the second - they play an online game;
- at the same time, the third computer is downloading a “heavy” file from a torrent.

Of course, an average router cannot withstand such a network load (especially if it is from “old times”) and cuts off the Internet connection. After rebooting the router, the Internet appears, the user again launches all suspended programs - and the situation repeats.

In this case, the optimal solution would be to buy a new, more powerful router. If for some reason it is not possible to replace the router, then on the “old” router you should set a limit on the simultaneous use of large Internet traffic.

2. Another common reason why the Internet through a router regularly disappears is outdated firmware of the device. Let's look at how to update the router firmware using the example of the D-link 2640U router:

There are cases when the problem of constantly losing the Internet is corrected, on the contrary, by returning to an earlier version of the firmware. The principle of operation is the same: download an “earlier” firmware and install it on your router.

Why the Internet keeps disappearing: other reasons

This reason is especially relevant if the Internet disappears due to “downtime”. To fix the problem, write in the router interface (in the tab) either the address of your provider’s DNS server, or any public one (for example, Google 8.8.8.8.)

4. In addition, the Internet on a computer or laptop may disappear due to virus activity.
This does not happen often, but it is one of the possible regular causes of interruptions in the Internet connection. Check your computer for viruses: a scan is not needed, but a complete one. For example, with the Doctor Web Cureit utility: first a full scan, and then a boot scan.

5. To diagnose your Internet connection, you can use third-party programs: for example, “VisualRoute”.

Or programs - optimizers. There are many such programs, but one of the most convenient is “TweakMaster”: the program is paid, but there is a 30-day demo version (that’s enough for one specific test). Using this program, build the most optimized network and test it for load: for example, start downloading a torrent or online game.

6. A break in the Internet connection may be due to physical damage to the router’s power supply or Internet cable (twisted pair).

Try connecting a different power supply to the router. If possible, check the cable for breaks or pinching.

If you have a multimeter or tester, you can “ring” the cable. To do this:

- use the tester probes to touch the orange and white-orange wires;
- further to the green and white-green wire: the resistance in both the first and second tests should be 1-2 Ohms;
- next, check the resistance between the green and orange wires: it should be at least 100 Ohms. If all 3 indicators are within these limits, then the cable is working.

7. Perhaps the reason for “losing” the Internet connection every 5 minutes lies not in the router, but in the computer itself. The most common situation here is outdated network card drivers. You can check whether this is the case in the “Device Manager”: if in the “Network Cards” section there is a yellow triangle with an exclamation mark, then it is necessary.

8. If none of the methods described above helped to fix the problem, and the Internet through the router still disappears every 5 minutes, then the reason is most likely on the provider’s side: contact technical support to check the status of your connection.

However, in most cases, the reason for interruptions in Internet connection lies in the router itself, and the best way out The solution to this situation would be to buy a new router.

Tp-Link TL-WR741ND and Tp-Link TL-WR741N routers are very popular. In fact, these are the same router, it’s just that the newer TL-WR741ND has a removable antenna. Perhaps there are some other differences in the hardware itself, but this is not known.

These routers from Tp-Link have proven themselves very well as inexpensive, high-quality devices for the home. Their prices are really attractive. The router is really worth the money, which is why it is so popular and easy to assemble huge amount reviews in online stores. Many Internet companies offer Tp-Link TL-WR741ND at a promotional rate. But, not without its drawbacks, of course: a weak signal, slow speed, and a problem that I will write about below. Although, considering its cost, this is quite normal.

Why does the Internet disappear on Tp-Link TL-WR741ND?

So, today I want to tell you about one problem that very often appears on the Tp-Link TL-WR741ND router and its younger brother. The problem is that the Internet simply disappears, both via Wi-Fi and cable. On computers, the status “Without Internet access” appears and a yellow exclamation mark appears next to the network icon. On mobile devices there is a Wi-Fi connection, but nothing loads and sites do not open.

This problem may appear on its own. But most often, the Internet disappears when you start downloading something, watching online videos, playing online games, download torrents, connect many devices, etc. Simply put, when you create a load on the router.

I think you already understand what the problem is here. Yes, the router simply cannot handle the load. People very often write that the Internet disappears on the TL-WR741ND when they try to download something or launch online games. This already suggests that the router simply cannot cope with such a load and simply “crashes”. Only saves.

What can be done?

You must understand that this is a weak, budget router, and this is basically normal. It is designed to connect 2-3 devices and be quiet. If you start downloading via torrent on one device, turn on online video on another, etc., then of course it will not withstand this load and the Internet will disappear. Moreover, if you also have Internet using PPPoE or L2TP technology, when the load is even greater compared to the same Dynamic IP.

I'm not saying that you can't play online games or download torrents through the TL-WR741ND router. It is possible, but only you must be prepared for the fact that such troubles can happen and the Internet may disappear.

If you have exactly this problem, then try completely disabling all programs through which you download and distribute torrents. If possible, disconnect multiple devices from Wi-Fi networks. If the problem persists, then it is possible that there are problems with the router's power supply. If possible, try connecting the router through a different power supply.

Update the firmware on your router. I wrote how to do this. Or see the instructions specifically. Perhaps it will work more stable on newer firmware.

There are no software settings that can remove this problem. Unless the problem appears when downloading torrents, you can slightly change the parameters in the program itself. Perhaps this will help. I wrote about this in the article: .

But, if you want stable operation, then it is best to buy a more expensive and powerful router. This is the best solution if you connect a lot of devices and put a significant load on the network.

Update: enabling protection against DoS attacks

In the comments, Andrey wrote about the solution, after which his TP-Link TL-WR720N stopped envying and losing its Internet connection. He simply enabled protection against DoS attacks.

In the section: Security - Advanced protection settings.

Enable "Protection against DoS attacks"
Enable filtering against ICMP-FLOOD attacks
Enable UDP-FLOOD filtering
Enable filtering against TCP-SYN-FLOOD attacks.

Honestly, I don’t know how this can reduce the load on the router. Maybe the provider’s equipment “attacks” the router, thereby creating additional load. But it's definitely worth a try.

I think it makes sense to also try to enable the function “Ignore Ping packets from the WAN port” on the same page.

Try it. Write about your results in the comments. Thanks to Andrey for the advice.

So, you have configured your wireless router, but for some reason something is not working. I will try to consider the most common problems with Wi-Fi router problems and ways to solve them. Most of the problems described can equally occur in Windows 10, 8.1 and Windows 7 and the solutions will be similar.

From my work experience, as well as from the comments on this site, I can identify the following typical problems that users encounter when, it would seem, they have configured everything exactly and according to all sorts of instructions.

The router status indicates that the WAN connection is down
Laptop, tablet, smartphone does not see Wi-Fi, but sees neighbors’ access points
Constant disconnections
Local city resources of the provider, torrent, DC++ hub and others are not available

If I remember other typical things like the above, I’ll add to the list, but for now let’s get started.

(provided that the router is configured correctly)
What to do if when connecting it says:
What to do if .

Wi-Fi connection disappears and low download speed through the router (through a wire everything is fine)

In this case, changing the wireless network channel can help you. We are not talking about those situations that also occur when the router simply freezes, but only about those when wireless connection disappears on its own on certain devices or in specific places, and it is also impossible to achieve normal speed Wi-Fi connections. You can read more about how to select a free Wi-Fi channel.

WAN is broken or the Internet is only on the computer

The main reason why this problem occurs is with WiFi router om - connected WAN connection on the computer. The point of setting up and operating a wireless router is that it will establish a connection to the Internet on its own, and then “distribute” access to other devices. Thus, if the router is already configured, but the Beeline, Rostelecom, etc. connection available on the computer is in the “connected” state, then the Internet will only work on the computer, and the router will take virtually no part in this. In addition, the router will not be able to connect to the WAN, since it is already connected on your computer, and most providers only allow one connection from one user at a time. I don’t know how clearly I was able to explain the logic, but even if it’s not clear, just take it for granted: for everything to work, a separate provider connection on your computer must be disabled. Only a local network connection should be connected, or, in the case of a laptop, etc., a wireless network connection.

It is impossible to access the address 192.168.0.1 to configure the router

If you encounter the fact that when you type the address to access the settings of your router, the corresponding page does not open, do the following.

1) Make sure that in the local network connection settings (your direct connection to the router) is set to: obtain an IP address automatically, obtain DNS addresses automatically.

UPD: Check whether you enter this address exactly into the address bar - some users, when trying to configure the router, enter it into the search bar, resulting in something like “The page cannot be displayed.”

2) If the previous point did not help, use the run command (Win+R keys, in Windows 8 you can simply start typing the word “Run” on the start screen), enter cmd, press Enter. And in command line mode, enter ipconfig. Pay attention to the “Default Gateway” value of the connection used for configuration - it is at this address that you should go to the router administration page. If this address differs from the standard one, then perhaps the router was previously configured to work on a specific network with certain requirements. You can reset it to factory settings. If there is no address at all at this point, then, again, try resetting the router. If that doesn’t work, you can also try disconnecting the provider’s cable from the router, leaving only the cable that connects it to the PC - this may solve the problem: make the necessary settings without this cable, and after everything is configured, reconnect the provider’s cable. Pay attention to the firmware version and, if relevant, update it. If this does not help, make sure that the “correct” drivers are installed for the computer’s network card. Ideally, download them from the manufacturer's website.

Settings are not saved

If for some reason the settings are not saved after entering them and clicking “save”, and also if you cannot restore the settings previously saved in a separate file, try performing the operation in a different browser. In general, in case of any strange behavior of the router admin panel, you should try this option.

Laptop (tablet, other device) does not see WiFi

In this case, the most possible different options and they are all about equally common. Let's go in order.

If your laptop does not see the access point, then first of all, check whether the wireless module is turned on. To do this, look at the “Network and Sharing Center” - “Adapter Settings” in Windows 7 and Windows 8, or in Network Connections on Windows XP. Make sure your wireless connection is turned on. If disabled (displays gray), then turn it on. The problem may have already been resolved. If it doesn’t turn on, see if your laptop has a hardware switch for Wi-Fi (my Sony Vaio, for example, has it).

Let's move on. If the wireless connection is turned on, but is constantly in the “No connection” status, make sure that the required drivers are installed on your Wi-Fi adapter. This is especially true for laptops. Many users, having installed a program to automatically update drivers or have a driver installed automatically by the Windows operating system, believe that this is the right driver. As a result, they often encounter problems. The required driver is the one that is located on the website of your laptop manufacturer and is intended specifically for your model. Laptop computers often use specific hardware, and using drivers (not just for network equipment) recommended by the manufacturer can avoid many problems.

If the previous option did not help you, try logging into the “admin panel” of the router and slightly changing the wireless network settings. First: change b/g/n to b/g. Did it work? This means that the wireless module of your device does not support the 802.11n standard. It's okay, in most cases, this will not affect the speed of network access. If it doesn’t work, try manually specifying the wireless network channel there (usually “automatic”).

And another unlikely one, but possible option, which I had to deal with three times, and twice for the iPad tablet. The device also refused to see the access point, and this was solved by setting the United States region in the router instead of Russia.
