Slow internet

An important role in the development of computer technology was played by the worldwide information computer network Internet, designed to connect users of computer networks and exchange information. The Internet has become such an integral part of our lives that many users use it daily for work and entertainment. Due to its ease of use and easy accessibility, the Internet has gained wide popularity. Considering the possibilities of the Internet, the range of its application is unusually wide.

For example, people receive additional education, learn the latest news, send and receive emails and messages, watch the latest movies and listen to music, have access to a huge amount of data and digital libraries, attend exhibitions and concerts, communicate with other people through social networks, etc. .d. Many users have founded or promoted their business via the Internet: provision of consulting services, creation and promotion of websites and Internet projects, sales through online stores, exchanges, creation and development of remote projects, advertising, business presentation through corporate websites, etc.

Therefore, it is not surprising that in order to achieve the goals set, a stable high-speed Internet connection is required, which allows access to the Internet instantly and without delay. However, this is not always possible to achieve. And when the Internet connection is slow, it turns into wasted time and money, forcing the user to look for the causes and ways to fix such a problem.

There are many different reasons that can affect your Internet connection and significantly slow down its speed. For example, the problem could be your modem or router, a weak “Wi-Fi” signal, insufficient signal strength on your cable line, other devices connected to your network and additionally loading it and reducing network bandwidth, or even a slow “DNS server”. In this guide, we will look at various troubleshooting methods that we hope will help you identify and fix the cause of your slow Internet connection.

Narrow down the range of slow Internet connection problems by checking through websites and additional devices

Internet speed test

Run an Internet speed test, and if it confirms that the Internet is really slow, then to narrow down the range of possible problems, you should try to navigate your browser to different websites and connect several devices in your home. If as a result, you see that only one website loads slowly, then this is probably a problem with the website itself, and not with your Internet connection. In fact, there is nothing you can do about it, except to wait until the support service responsible for the functioning of the site fixes this problem.

Reducing the possible variants of the problem will help you identify and fix it faster. Does the process of slowing down the Internet connection only occur on one computer, or does it repeat itself on all your devices? If this is just one computer, then you know that the solution to the problem will probably have to be found here. You may just need to restart your computer, or you may need to run a full computer scan for malware with your antivirus to make sure everything is in order. If your internet connection is slowing down on multiple devices – for example, on multiple computers, or on your personal computer and your phone, then it’s almost certainly a network issue and you’ll need to check and tweak your router.

Check the speed of your Internet connection and compare it with your data plan

Before moving on to solving the problem, it is worth doing a test check of the Internet connection speed to find out how effective it is and how it corresponds to the declared plan or package to which you are connected. The test can be done in different ways: using special applications or using various websites. Choose any method that suits you. Be sure to stop any data downloads, updates, video streaming, or other heavy internet activity before running the test to ensure as little interference with results as possible.

Compare your speed measurements with the expected speed of the Internet connection you are paying for. If you do not remember the value of the guaranteed Internet connection speed for your tariff plan, then you can find it: in the contract for the provision of services for connecting to the Internet; on the invoice presented to you for payment by the Internet service provider; on the website of your Internet service provider or on a page in your personal account of this website.

However, there are some caveats here. Speed ​​tests can sometimes seem quite high as some ISPs may prioritize and have servers located very close to you. If the connection speed is slightly lower than what is declared in your tariff plan, then this is normal – usually, all tariffs indicate the condition “up to” a certain speed, and you do not always get the exact speed that you pay for. Also, the speed of the Internet connection may sometimes slow down at a busier time of the day when most users use the Internet connection than at other non-peak times when many are sleeping or at work.

Of course, it is also possible that you initially chose a data plan with a low Internet connection speed – in this case, you will need to contact your Internet service provider and select a different, faster Internet connection tariff plan.

However, if you are paying for a certain internet connection speed and are consistently getting significantly slower speed test results, then it’s time to move on to the troubleshooting steps below.

Restart your modem and router

Restart modem and router

Like personal computers, modems and routers can sometimes slow down your Internet connection due to being in a slow and congested state. This problem can be easily fixed with a reboot. If you haven’t rebooted your router or modem in a while, you should definitely do so now.

If you have a combo modem/router, you can simply reboot your device by pressing the reset button on it. Or simply unplug the device from the electrical outlet and wait for ten seconds before plugging it back in (some ISPs, depending on the settings of their equipment, may recommend disconnecting the modem and router for up to five minutes). It may take some time for your device to be able to reconnect to your ISP and provide you with Internet access, so take your time and be a little patient. Then check if your speed has improved after reboot.

Improve your “Wi-Fi signal”

Check your Wi-Fi

Your Internet may be fine, but your Wi-Fi network, which connects your computer or mobile device to the Internet, may have some signal problems. A bad “Wi-Fi” connection can turn out to be an internet connection issue, especially since it can affect every device in your home. There are quite a few reasons why you might have a bad “Wi-Fi” signal. Airwaves can be overwhelmed by a large number of nearby devices, especially if you are using the 2.4 GHz frequency band rather than 5 GHz, which allows the network to support many more devices. This is a particularly common problem in denser urban areas – for example if you live in an apartment complex with neighbors who have a bunch of wireless routers and other devices.

You may also just have a dead zone, perhaps something is interfering with your “Wi-Fi signal” or poor coverage in your home. Check with your Wi-Fi signal provider to find out how you can speed up your Wi-Fi connection and get a stronger signal.

If your existing “Wi-Fi signal” strength is not enough for you and you need wider coverage, then consider setting up a mesh “Wi-Fi” system, which includes several base stations that greatly expand the “Wi-Fi” area. signal”.

Stop overloading your connection (or try QoS)

Devices on the network can overload your internet connection

Your Internet connection is used by all devices in your home that has permission to access it. Therefore, other devices on the network can overload your Internet connection, slowing it down for everyone else.

For example, if you are streaming high-definition video on the network online, and additionally, from another device, they try to download a file via a torrent and also watch the streaming video, then each of these processes will slow down. Stop (or slow down) some of them to speed up your Internet connection.

If this problem appears quite often, then you may need to upgrade your Internet connection plan to a higher-speed package. However, you can also find out if your router has a Quality of Service (QoS) feature that will allow your router to automatically prioritize and throttle the bandwidth of various devices and services. For example, it can automatically throttle torrent bandwidth to avoid slowing down the streaming video.

Checking coaxial separators

Checking coaxial separators

If you have cable internet and you have coaxial cable splitters on the line going to your cable modem, then this can reduce the signal strength and result in a slower internet connection. Splitters vary in quality, and a bad or cheaper one can significantly reduce your Internet signal strength than a higher quality splitter. Many splitters can also cause a problem and reduce the quality of the Internet connection.

If you have splitters on your cable line, try disabling them to troubleshoot your Internet connection. See how your Internet connection works without any splitters on the line. If your Internet connection speed increases significantly, then you were able to solve your problem.

Try setting up a different “DNS server”

Check DNS servers

In some cases, changing the “DNS Server” may increase the connection speed if the “DNS Server” offered by the service provider by default is slow.

The way DNS works are that when you connect to a site like, your computer contacts its “DNS servers” and queries it to determine the numeric “IP address” associated with After receiving a response, it connects to this “IP address”, which can be something like “”, and then connects to this address.

Typically, the “DNS servers” you use when you connect to the Internet are provided by your ISP. But if they are slow or heavily congested, then you can get a faster Internet connection by switching to a different set of “DNS servers” (for example, you can use the “Google Public DNS” and “OpenDNS” public servers, which are very popular).

Call your ISP and report the problem

If you’ve tried all the troubleshooting steps above for a slow internet connection and can’t fix this issue, then it’s most likely not your problem. This may be a problem with your ISP. For example, there may be a problem with the cable line from your home to your ISP, or any other equipment it has installed. In this case, you should call your ISP and report the problem.

You are paying an ISP to provide you with a stable Internet connection, and it is their job to ensure that you have that connection and fix any Internet access problems that may arise. Just make sure the problem is with the ISP and not with you or your equipment.
