What is internet lag? Viruses on another computer on the local network. Poor location of the Wi-Fi router
It's very easy to place an order. Just fill out the order form or call.
A lot depends on the speed and stability of wireless Internet these days. Work, personal life, the opportunity to always be in touch with loved ones, relaxation, self-education... You can’t list everything. Therefore, for many people, the Internet suddenly starting to “slow down” is equated to a small apocalypse. What could be the reason for the failure? And what to do in this situation? IT technology experts give their advice.
Poor quality equipment
The problem with low connection speed is often associated with the low power and meager built-in memory of the router. So it's not worth saving on it. The situation is exactly the same as with computers or smartphones: the cheaper the device, the weaker its processor and the smaller the amount of memory. For 1,300 rubles it is quite possible to purchase a router that will cope with a light load. But if you plan to download a large amount of information or conduct online broadcasts (in a word, do something that requires stable high Internet speed), it is better to pay attention to devices costing from 4,000 rubles.
"Peak hour"
It may seem strange, but the speed of wireless Internet depends on how many people are simultaneously connected to you through the same port. If you have a large family, then in the evening, when everyone goes online to chat, watch a movie online or play, the speed will drop. There are several options:
- Install multiple access points.
- Buy a tariff with a speed of at least 20 Mb/s (and, of course, make sure that your router supports this power).
- Agree with your family about a schedule for using the Internet.
Low cable bandwidth
In some cases, you can get rid of problems with the Internet by simply changing the USB cable running from the router to the computer. The higher the cable performance, the faster the information will be downloaded. In addition, cords wear out over time and, accordingly, their capacity decreases.
Poor location of the Wi-Fi router
A big mistake is to assume that if you have a router with Wi-Fi support, the Internet will be equally stable everywhere. The signal strength depends on the location where the router is installed. What can you do if the Internet is slow?
- Make sure that the router is not blocking any large object. It is better to place it in an open space. Many users hide their Wi-Fi router in a closet or table to save space. This is only permissible if the device has enough power to create a stable signal.
- In some cases, you can speed up the Internet by raising the router higher or, conversely, lowering it. Optimal height above the floor will have to be determined experimentally.
- Try moving it closer to your workplace. In large apartments or office buildings, the signal strength may weaken away from the router.
Cheap plan
It’s trite, but this is one of the most common causes of “problems” with the Internet. If the tariff you paid guarantees a speed of up to 2 Mbit/s, then a movie weighing 1.5 GB will download for several hours. Of course, doing something resource-intensive in a browser will also be inconvenient.
In this case, it is worth measuring your Internet speed on one of the specialized sites, familiarizing yourself with the offers of providers and choosing the most suitable tariff for yourself.
Router failure
If a connection problem occurs unexpectedly, then most likely your router is simply frozen. Don’t be surprised: this device has the same operating principle as a computer or smartphone, and it can also experience an internal failure.
Most routers have a key that allows you to easily reboot the device. If it is not there or you do not know where it is, you can do one of the following:
- Press the power off button.
- If it does not work, hold it down and hold it for 15-20 seconds.
- As a last resort, you can simply unplug the power cord from the outlet.
You need to turn on the router no earlier than 30 seconds so that the overload that occurs in the electronics of the device has time to disappear.
Software problem
There is no Internet on your smartphone, or its speed is very low, while other devices easily access the network? No need to try to configure your router! The problem is with the smartphone. Perhaps your Wi-Fi is simply not configured. Or you need to install new drivers. Or perhaps the built-in memory is not enough for normal operation. In such a situation, it is better to contact a specialist who will tell you whether you need to reinstall the software or whether it is enough to simply perform the setup correctly.
Running background task
Many users forget to turn off applications after they are finished using them. They continue to work in the background and take up part of the Internet. Which, accordingly, ceases to be enough for other tasks.
Running programs can also reduce speed because they use a significant part of the device’s built-in memory. This is especially true for low-cost smartphones, tablet phones and budget laptops.
To speed up your internet, try the following:
- Close all unnecessary browser tabs. It is best to leave only one - the one you are currently working with.
- Did not help? Then additionally clear your browser cache.
- Turn off running programs or applications. In Windows, this can be done through the Task Manager. Mark with your mouse unnecessary application and click on the “End task” button at the bottom of the window.
- If you have any computer cleaning program installed, such as CCleaner, delete all temporary files.
As a rule, these simple steps can significantly speed up not only the Internet connection, but also the gadget itself as a whole.
The signal is jammed by other electronic devices
The cause of an unstable Internet connection may lie in devices that emit radio frequencies. It could be a TV, remote control remote control, car radio. It’s easy to check whether they affect communication: step aside and try to access the Internet again.
If the suspicion is confirmed, you will have to make a small rearrangement: move the router as far as possible from the “hostile” equipment, ideally, in another room. Make sure that there is nothing else between the router and the place where you usually use the Internet that could jam the signal.
In most cases, problems that arise can be easily solved using one of the methods listed above.
This article is intended to answer two of your questions: why does the Internet slow down, and how to deal with it? If you are sure that your Internet speed is lower than that stated by your provider, then this article is for you.
To make it easier to understand the reason for low speed, we will divide all the reasons into those that depend on you and those that do not. The first is those problems that arise with your equipment, and everything else is problems with the provider’s equipment that are independent of you. Many providers do not admit that they are to blame for the low speed, and upon departure they issue quite large bills for the provision of their services. So, why is the Internet slow?
Reasons up to you:
1.Viruses
Spyware, Trojans, worms - all of them can significantly reduce the speed of the Internet. They are embedded in the browser and can use the entire Internet channel, track your actions and keystrokes (keylogger), send information and your data to their owner. There are cases of complete loss of communication.
2.Antiviruses and firewalls
Enough common cause low speed - antiviruses and firewalls. Such programs “on the fly” check data coming from the network, which is reflected in the connection speed. But not all antiviruses slow down the Internet too much. Try turning off the Internet and checking the connection quality again; if this is the problem, then you should think about replacing the antivirus.
3. A large number of network programs and add-ons.
All kinds of chat rooms, downloads, add-ons and plugins in the browser, bars, can significantly reduce the speed of the Internet. Try turning them off before measuring speed. If the difference is significant, think about whether you really need all these programs, and whether you need these half-monitor bars with information about quotes, weather, etc.
4.Operating system (OS)
Quite often the problem is solved by reinstalling Windows, because... works on regular distributions a large number of unnecessary services that not only use network resources, but also hardware resources.
5. Incorrectly configured wireless equipment.
If you use a wireless router (WiFi), it is possible that your neighbors can take advantage of such a freebie; you don’t even have to be a hacker to do this. Even your neighbor, a schoolboy, can try his hand at using your Internet out of interest.
To prevent this from happening, when connecting all your devices to the router (computers, laptops, netbooks, mobile phones, tablets, game consoles), be sure to use data encryption and enable a MAC address filter, indicating the addresses of all your devices.
6 . Technical limitation routers And modems
If you are using an access point and the speed does not suit you, then try to exclude the router from the chain by connecting directly to the modem and measure the speed. This problem often occurs if the router does not support high data transfer rates, i.e. lower than that of the provider. In any case, read the information about your equipment, specifications, customer reviews.
7. Malfunctions network cards
A fairly common case, but the malfunction will not be obvious. That is, the network card seems to be working, is identified as a device, shows the connection of the network cable, it may even be under warranty, but there is still a problem!
If it is possible to check the speeds with another device (laptop, computer) and if it shows a higher speed, then the problem is most likely with the network card. First, you need to reinstall the driver to a newer one, and if it doesn’t help, then you need to replace the network card (not an expensive matter); if the problem is in the laptop, an external network card will help.
In such cases, it helps as a temporary solution to force the network card to set to 10 Mbit/s mode, always Full Duplex, this is enabled in the network card settings, additional tab, Speed&Duplex or Connection Type section. By configuring the network card in this way, you will limit your connection to 10 megabits, but will make it more stable. And remember that the problem will remain, and this is a temporary solution until a specialist arrives or the card is replaced. The same temporary solution helps with poor quality cables or connections.
In any case, you need to make sure that the problem is really in the network card.
8. Network cable problem
At this point highest value has connection qualityconnectors and network cable. The cable is laid in such a way as to exclude any physical interactions.Over time, the copper wire oxidizes and thereby deteriorates the quality of the connection. They extend the cable incorrectly, without paying attention to the length of the turn in the pair, and the result is low speed and poor signal quality.
Reasons beyond your control.
Problems on the line in general
The problems may not be within your apartment. Due to poor-quality connections and oxidation of wiring in basement pipes and underground wells, Internet speed is significantly reduced, and sometimes disappears altogether. You can check the line very in a simple way. Run ping on the command line10.8.0.1 - t – l 1500 (specify your gateway or VPN server) where -l 1500 sets the size of the sent packet to 1500 bytes.
After starting the ping, watch the response for a while (time = 2ms.) If the message appears periodicallyTimed out request This means that your packets are lost before reaching the gateway and are sent back, after which the system tries to send them again. All this requires time, which you spend waiting for the page to load in the browser.
Summarize. I talked about the most common problems affecting Internet speed. In general, troubleshooting is determined by the method of elimination, one by one of the points described above. I wish you good luck and a quick connection!
Tired of waiting for a website to load and the Internet running very slowly? So it's time to figure out why this is happening.
On forums about computers, topics often appear with the headings “The Internet is slowing down, what should I do?”, but it is impossible to solve the problem in one action, since there are many reasons for such phenomena.
We'll look at common reasons for slow Internet speeds, and you'll have to determine what exactly is stopping you from using high speed connection. I would like to say right away that first of all, contact your Internet provider, since the problem may be related to technical work or failures.
7 reasons why the Internet is slow
- Viruses. Be sure to update your antivirus and run a full system scan. It is quite possible that some Trojans and worms are sending various requests, thereby slowing down the speed of your connection.
- Security software. Some antivirus and security programs can cause slow internet if it is scanned on the fly before traffic arrives. To be sure this is not the case, disable your security software and test the speed. If necessary, disable the firewall.
- Downloading various updates. Many users don't even pay attention to how many programs they have running all the time. For example, you may have an antivirus database update running, Windows, various instant messengers, clients, and so on. All this reduces the speed of the Internet.
- Operating system. What if you just installed the operating system, and there are no viruses or additional programs No? In this case, the problem may be related to the OS itself. This is especially true for those who install non-standard versions of Windows (Zver). For example, because of this, original drivers for the network card may not be installed.
- Setting up network equipment. Connecting to the Internet can be done through various devices (modems, routers, routers, etc.). All equipment must be configured separately and ensure that it is accompanied by up-to-date drivers, clients, software and so on.
- Network card failure. Not so often, but still there are speed problems due to a broken network card. This is easy to determine; just plug the Internet cable into any other computer and measure the speed.
- Cable problem. Many people are sure that the Internet cable may or may not work, but there are also situations when it reduces the Internet speed. The cost of twisted pair is not high, so just buy a new cable and check if this is the problem.
Modern technologies make it possible for household users to reach speeds of up to one gigabyte. But a slow connection prevents you from fully enjoying all the benefits of the information age.
The Internet can slow down for many reasons, ranging from viruses to line problems. With proper skill, the user can cope with most problems himself. But first you need to discover them.
Viruses
Due to hacker programs and modules, the Internet takes a long time to load information.
There are a number of prerequisites that allow you to determine the presence of virus software:
If you discover any of the above while working, you need to scan your computer for viruses. In the presence of antivirus program It's worth thinking about an alternative. Since the installed software module does not cope with the task.
Before scanning, you need to update the virus databases to the latest version. If you are interested in what programs can help in this situation, then the best healing utility is Cureit, developed by the dr.Web laboratory. It performs a deep scan and can eliminate the most dangerous viruses.
After completing treatment, the best solution would be to change the antivirus utility. Avast is considered one of the best free applications. It puts minimal load on the system and provides decent protection. As an alternative, it's worth considering Kaspersky Internet Security.
You also need to check your firewall and configure it to work with programs that have an Internet connection. Moreover, it is important to avoid dubious sites. They are the ones that most often contain malware.

operating system
Sometimes the reason why the Internet is very slow is the operating system. For example, this situation is possible when the system disk is full and the OS cannot quickly access the required entry. It is enough to delete part of the data from the system disk to get rid of this defect.
The best option old restore points and temporary files will be deleted. Be sure to empty the trash. Remember, storage space for data sent there is reserved on the system hard drive.
Additionally, you need to take care of cleaning the registry. For this it is better to use CCleaner. It will carefully erase outdated records without harming the operating system.
If after carrying out maintenance work the loading speed remains the same, perhaps the reason lies in poor-quality OS assembly. Unlicensed versions of Windows often cannot work properly with the network.
For example, the computer does not receive an IP, the ping disappears, or unstable drivers were installed at the very beginning. In this case, the only solution is to reinstall.
Antiviruses and firewalls
In some cases, difficulties arise due to the antivirus. This is due to the fact that the program checks information when loading web pages. If the verification algorithm is too complex and the information packets are large, the download will take a long time.
Disable the firewall for a while to test this hypothesis. If the flow of data reception has increased, then the problem is with the antivirus. The best option would be to change the security utility settings, lowering the security level. Or you can find an alternative program that will use fewer system resources.
Incorrectly configured wireless equipment
Most users prefer wireless routers to connect their devices to the network. Incorrect configuration may result in unauthorized access and reduced download speed through the router.
Therefore, you need to set data encryption and appropriate settings. It wouldn't hurt to change your access password to a more complex one. It is best to use numbers and letters in combination.
Router limitations
To set restrictions, connect all devices to the network. Then go to settings and enable MAC address filter. Enter the details of the connected gadgets in the appropriate fields. Make a couple of test visits to the Internet.
If nothing has changed, connect the computer directly to the cable. If changes are detected, we can conclude that the reason is in the router itself: its characteristics are not enough to ensure comfortable surfing on the Internet.
- go to the official website of the manufacturer;
- download the updated firmware;
- perform the installation.
Some operators create unique firmware for the routers they sell. Try installing it too. Also keep in mind that most products only indicate the ability to connect to a network designed for 100 Mbit/s (Ethernet 100 Mbit/s). This does not mean that the device will work at the same speed.
When choosing a router, you need to pay attention to the following parameters:
- Static IP;
- Dynamic IP;
- PPtP;
- L2TP;
- PPPoE.
They indicate the actual transfer of data between WAN and LAN. These indicators are published on the pages of manufacturers or independent testing laboratories. The last attempt to increase the speed of the router is to switch the device to bridge mode.

Internet slows down after reinstalling Windows
Check if your laptop is responding system requirements new version installed OS. Test the network on other browsers. Make sure you use latest version search engine. If this is not the case, please update.
Do not write off the incorrect operation of drivers installed in automatic mode. Go to the motherboard manufacturer's website and download the appropriate software. Then make a replacement.
Important! Sometimes, in order to achieve good network performance on a new OS, you need to increase the volume random access memory or implement more radical modifications to the PC.
Network card problems
A faulty network card is difficult to notice. The device may be normally detected by the system and respond to the connected cable, but this does not mean that it is working properly.
The best option would be to connect another PC and test the Internet on it. If everything is fine, reinstall the drivers on the first computer. Ideally, you need to install a different network card and try to download data from some site.
Some cards have Full Duplex functionality. It is located in the Speed&Duplex or Connection Type sections. Set the download to within 10 Mbps. If the device is faulty, this will help stabilize the channel for a while until a replacement is made.
Cable defect in the apartment
If the cable is broken, the system usually shows that there is no network as such. Without specialized equipment, the break point can only be found manually. After detecting damage, it is necessary to twist the copper wires and insulate them.
Attention! If you decide to replace the cable yourself, consider not only the number of pairs, but also the presence of pairs.
Otherwise, after replacement the speed will be extremely low. It is logical to assume that you are interested in how to make the laid cable work stably?
There are a few simple rules, which must be followed when laying wires in the apartment:
- lay the cable in such a way as to exclude all possible impacts on it - it is best to do this on top;
- use a drill to create holes in the walls; interior doors should not break the wire;
- use special protective skirting boards to protect the wire;
- avoid twisting.
These simple precautions will ensure long and stable operation of the cable.
Problems on the line
After all of the above methods for increasing speed have been tried, all that remains is to test the speed of data packet exchange with the provider. To check the line you need to run the Ping.exe file. It is usually located in the System 32 folder. To save time, use the search bar.
Replace 10.8.0.1 with your gateway. The data packet size is 1500 bytes. Run ping. If everything is in order, a picture like the one above will appear. If the message “Request timeout interval exceeded” appears, contact technical support.
To restore file download speed, you will have to find the problem by elimination. In most cases, an advanced user’s knowledge and the desire to receive information from the network at high speed are sufficient to resolve the problem. In particularly difficult situations, you will have to contact technical support.
