Why is my download speed so slow all of a sudden?

When your download speed is unreasonably slow, it might be due to a variety of factors.

It can be due to the router settings, ISP issues, and physical damage to your wires and devices. 

Continue reading to figure out some of the most common causes slowing yours down and how to solve them…

Device overheats or overruns

Heat is an enemy of electronics, especially computers. 

If your computer becomes too hot, it may become unstable.

If your PC feels warm to the touch or you suffer sudden shutdowns, screen freezes, or the dreaded blue screen crashes, your computer may be overheating.

In this case, the first thing you should do is find out the underlying reason.

You may have too many active tabs in your browser or be performing intensive tasks like playing games, editing multimedia files, or streaming videos online.

After that, you’ll know if your PC has to be physically cleaned, the airflow needs to be improved, or some browser tabs need to be closed.

Notably, give your computer a break and shut the resource-intensive app for a time if it is running hot but otherwise functioning normally.

The router is in the wrong place

The distance between your router and your device, though sometimes overlooked, is critical to your Internet performance. 

The closer you are to the router, the stronger the signals, and hence the faster your Internet connection.

Additionally, WiFi signals have a low enough frequency to penetrate materials like walls. 

However, WiFi signals can be greatly weakened and blocked by objects like stone, water, metal, and tile.

Therefore, position the router where the least amount of walls must be crossed for the signal to reach the device.

Ideally, put the router as centrally as you can as the signal spreads out in all directions to ensure every room in your home is within the WiFi signal's range. 

Try extending the antenna in a different direction or adding a WiFi extender if moving your router is not an option.

Your WiFi signal will be strengthened, extended, and distributed in various directions as a result.

Connection speed is slow

Well, it’s also one of the answers to the question of Why is my Chrome download speed so slow.

Your ISP's claimed speed is only valid under ideal situations, such as when your equipment has no congested websites, rush hours, or logical or physical defects.

Sometimes, your actual speed may be much lower than the quoted megabits.

Your router is outdated

An out-of-date router acts as a bottleneck, slowing down web downloads and file transfers between connected devices.

Some individuals never replace their routers, particularly those who continue to use the router that their Internet service provider lent them years ago. 

These routers, which frequently double as modems, are frequently sluggish and limited in range. 

It is, therefore, time to purchase a fresh, speedier router.

A newer router could improve your WiFi performance because older models use outdated wireless standards.

So how can you tell if your router is new or old?

Verify the router and you'll see figures as follow:

  • 11ac: It runs the most recent standards => Good

  • 11n: It’s a little dated but still useful => OK

  • 11g: It’s quite outdated, thus it's likely time to replace it => Not good

Multiple connected devices

Do all members of the household arrive home at the same moment your Internet suddenly becomes slow?

If so, your bandwidth is the cause of your slow Internet issues.

It resembles traffic congestion during rush hour quite a bit.

There is no other way to avoid or reduce traffic but to reduce the number of vehicles on the road or find a method to widen it.

The bandwidth is identical to that of this road.

It cannot handle the data traffic that your housemates are producing if it is too low.

The extender must be plugged into a power outlet located halfway between your router and the dead zone area to produce the best results. 

The WiFi signal from your router can then be picked up by the extender and extended further inside your house.

Remove any gadgets that use a lot of data

You may think having the Apps running in the background is OK when you are not using them.

However, instead, it uses your WiFi Internet signals and might slow down your Internet connection. 

You can switch off any apps when you are not using them.

It is also a good habit to turn off your mobile WiFi when you are not using it.

If you’re using Windows 10, follow these steps:

  • Choose Start => Settings => Privacy => Background apps

  • Check if the “Let apps run in the background” has been turned on

  • Turn the settings of each app On or Off under the “Choose which apps can run in the background”

Frequently Asked Questions (FAQs)
Why is my Internet so slow but the speed test is fast?

A speed test only measures your network connection in real time.

Thus, the results from tests performed a short while apart may differ slightly depending on network congestion and available bandwidth. 

Hence, make sure you're testing the same connection and testing to the same server if your testing results are noticeably different.

What is a good download speed?

At least 100 Mbps for downloads and 10 Mbps for uploads are considered good speeds. 

You can watch Netflix or YouTube, participate in Zoom meetings, and play most online games on multiple devices at once with 100 Mbps downloads.

Why is my 100 Mbps Internet Slow?

Your capacity may be constrained by the WiFi protocol that your hardware supports. 

100 Mbps is not supported by some WiFi standards. 

Similar to this, various factors, such as electrical interference, distance, etc can affect the speed of your WiFi connection.


By finding out the reason for a sudden sluggish download speed, you can discover a few simple ways to fix your device. We hope our explanations and suggestions for Why is my download speed so slow all of a sudden can help you improve the situation as quickly as possible.
