Why Is My Internet So Slow All Of A Sudden? [Fix 2021]

When we are all getting used to 5G internet globally, minimal lag can make us impatient. Whether you have a domestic or a corporate connection, not getting the promised speed is irksome. In an era where everything depends on the internet, speed has become the lifeline of the service. Everything from minimal daily tasks to critical and emergency services is all dependent on the network. To resolve any troubles, it is vital to understand why is my internet so slow all of a sudden. There are several reasons behind this; poor Wi-Fi modem and bad service from network providers can all play a role in the hazard you are facing. However, each problem comes with its solution and if you recognize the real reason behind the internet trouble, finding out the relevant solution also becomes very easy.   There are several websites and apps which are specifically designed for speed testing your network connection. When you purchase an internet subscription, a specific speed is promised to you. These websites help you check in real-time whether you are getting the promised service or not. Once you are confirmed that the speed is much lower than what it is supposed to be, it is time to look up the reasons behind the trouble. We have listed some of the most common issues that internet users complain about along with their possible solutions. Overloading the Wi-Fi, virus in the system, and network failure all are reasons which occur daily. If you are wondering why is the internet suddenly slow, read on and find out the reasons in detail.

Common Reasons For Such Faults And Solutions:

The following are some of the major reasons behind the internet suddenly slowing down and we have also provided the basic methods to solve these issues:

Often, it’s the Wi-Fi reception that leads to slow internet. Even when you have invested in a fast connection, the Wi-Fi can degrade the speed somewhat. This happens usually if the device’s reception by default is not up to the mark or it is located too far from the device you are trying to connect. Also, note that you are not always going to get the ideal speed that has been promised. The following are the ideal speed limit for each wireless technology:

  • 802.11ac: 50-80 Mbps downstream
  • 802.11n: 25-30 Mbps downstream theoretically is the internet speed is good otherwise it can go much lower.
  • 802.11g: 5-15 Mbps downstream

The best solutions when the primary problem arises from Wi-Fi reception are as follows:

  • Consider upgrading the Wi-Fi modem if it is still based on 802.11g technology.
  • Reboot the Wi-Fi modem, especially if it is used round the clock.
  • Do not connect devices up to the modem’s limit.
  • If possible, stay nearer to the modem while you are using the internet.
If the internet connection qualifies the speed test and you are still suffering from internet suddenly slow, the problem may be with the bandwidth of the server. When you are opening a specific site, you are not the only one accessing the server- there are a million others like you. So, if the bandwidth is not enough, there will be significantly lagging. The easiest way to confirm this is by conducting a speed test. Next, check a website you are familiar with and know for its fast downloadable content. Start a download and note the speed. If it is as fast as it should be, the problem is with the server and not your connection.  

There are so many times we put something on download and forget all about it. This is a common scenario when you have multiple devices in the house. With unlimited internet, this may not be a major problem but when websites like BitTorrent are running, the speed gets lowered. This is because the website uploads the files you have finished downloading to an unlimited number of people unless you close it. Downloading is stopped when the file arrives on your device. However, when you are trying to upload something while such a website is running in the background, you will witness a major lagging.

Steps To Improve Internet Speed:

By this point, you are probably wondering why is my internet so slow all of a sudden and how I can fix it. Now that you know the primary reasons behind the connection becoming this slow, we will give you the solutions in detail.

The router is essentially an electronic device that is running twenty-four hours every day. This leads to heating up and it can eventually damage the device in the long run. The earliest sign of damage is the device hanging time and again. To sort this issue, rebooting it is the easiest solution.

Here’s what you can do:

  • Keep the Wi-Fi turned off and let it rest for some time every day.
  • Let it cool down and if needed, unplug it completely from all power supplies.
  • Once you have rebooted the device, reconnecting will take some time and the router memory will be affected, but be patient and let it connect. It will be back to normal in a few minutes.

A Wi-Fi with a signal problem can also make the internet slow all of a sudden. This means you will not get the optimum speed even when the internet connectivity is good. The Wi-Fi signal is hampered when the airwaves within the house are congested with too many devices, especially if the frequency is 2.4GHz. The problem is particularly common for users in dense urban regions. Also, having a dead zone which means anything in the house that is interfering with the device also causes this trouble. Other devices which interfere with the Wi-Fi signal can make the internet speed suddenly slow. The easiest solution is to keep these devices turned off for the time being. Another thing that you can do is having a mesh Wi-Fi system that has multiple devices that can be placed all around the house or the property. This way, uniform connectivity, and no lagging are made possible.

If you are in your backyard wondering why is my internet suddenly slow while your Wi-Fi router lies near the foray- there you have the answer. The position of the device also plays a vital role in the speed that you are experiencing. The nearer you are to the router, the better is the speed. If you have a large property, the Wi-Fi router should also be of significant strength so that the network access remains uniform throughout the place. Talking about such routers, we have reviewed long distance wifi antennas, check them out. If you do not have a Wi-Fi that is powerful enough, then consider investing in a Wi-Fi extender. As the name suggests, this is a device that can extend the range of your Wi-Fi router and the speed will be improved from all the corners of the house. A simpler solution or rather a quick fix is finding out a place in the house in the central part where the router can be repositioned such that the Wi-Fi strength remains uniform all around the house.  

Often switching the DNS servers can also help to improve the internet speed. If the DNS server of your default service provider is slow, you can switch to another set of the DNS server. However, to do this, you must know the alternate DNS server address to which you can switch. The information is available through Google Public DNS and OpenDNS. Other than that, you can also ask the service provider for the solution when the internet slows all of a sudden.

Frequently Asked Questions (FAQ's)

The current DNS Settings can be changed to get faster internet when nothing else is working. It is a safe method and is reversible. This will not interrupt your network connecting in any way but make sure you are inputting the right alternate DNS server address.

Wi-Fi repeaters, boosters, and extenders all perform the same task and more or less work on the same technology. The difference only lies in what the manufacturer chooses to call their product. However, different types of Wi-Fi extenders work differently. The specifications and configurations are slightly different.

Check the specifications of the Wi-Fi extender like the routers it is compatible with. In case you are not sure about your router’s specification, you can also choose a universal Wi-Fi extender. Do note that, to get improved network reception, your Wi-Fi extender must be compatible.

This depends on the range and power of the router that you are using. The best rule of thumb is to draw the limit within 25 devices at most provided all are being used for minor casual browsing. If heavier activities are done like downloading and movie or live streaming, reduce the number of connected devices first.

There are different models of Wi-Fi extenders available. Some of the best options you will find are Netgear Nighthawk X4 AC2200, TP-Link TL-WA850RE N300 Wireless Range Extender, D-Link DAP-1610 AC1200 Wi-Fi Range Extender to name a few.

However, irrespective of the model you choose, it will only give the best results if it is compatible with your device.

Conclusion:

Many instances make the internet slow all of a sudden. While it is very annoying, recognizing the right source of the trouble can save a lot of time and effort. We have shared some tried and tested solutions to improve the internet connection wherever you are. These are the basics but enough to quickly fix any trouble that arises regarding the speed. Now that you know how to fix the slow internet, enjoying all your network-dependent activities will become much easier. Whether you use a Wi-Fi-extender or simply upgrade the router- keeping internet speed issues at bay is hopefully going to be a cakewalk for you now.
