We all know how frustrating it is to deal with slow internet while working on a computer. Even after restarting the router two or three times, the connection does not appear to improve. But, other devices under the same router may seem to work fine, indicating that your computer is not getting the connection required.

So, why is your internet slow on one computer but fast on another? This can happen simply because of the distance between your PC and the router. However, you can also face slow internet due to a virus attack or a slow VPN connection.

While this issue is quite irritating, the good news is that there are several options for resolving it. Continue reading to learn how to prevent similar issues from occurring in the future.

The Primary Causes of a Slow Connection on One Computer

Here are some significant problems one must know as to why your internet is slow on one computer but fast on another:

Internet Slow on One Computer but Fast on Another

The Router is Not Close to the Computer

This is the most prevalent issue when we have a slow internet connection. When a house is large and only has one router, the areas do not appear to cover completely, resulting in the internet slowing on one computer but fast on another.

There Might be an Existing Virus on the Computer

Many individuals are unaware that computer viruses can cause their internet connection to slow down. What’s even worse is that a computer virus can corrupt and erase everything saved on your PC.

Lack of knowledge of computers

Although not everyone has the intelligence to understand computer components, most people find this a problem. It is critical to understand the exact quantity of power used by a computer. Of course, it varies from computer to computer.

For a computer to work smoothly, knowledge of memory space or disk space is also required, as these factors have a significant impact and are frequently cited as reasons why the internet is slow.

VPN Can Slow the Internet Connection

Using a VPN with a small number of servers can cause your internet connection to slow down. Some VPNs consume higher bandwidth in exchange for making you anonymous. Therefore, you should always utilize a good paid VPN.

Using Busy Web Servers for Streaming

When a new episode of any anime or series is released, the server can become exceedingly slow. The slow internet connection is frequently due to many individuals simultaneously checking in to the website to watch the episode. The internet connection is also slowed as a result of this. So, always try to determine if a website has too much traffic.

How To Fix Slow Internet In One Computer

Well, the good thing is that fixing a slow internet connection on one computer doesn’t require expert knowledge. You can do it all by yourself in your home’s comfort. And here’s how:

The router is not close to the computer

Call the ISP

Before jumping to any conclusions, be sure your office’s internet server is down. If the office personnel suggest restarting the router, see if the internet connection is still slow. If the connection is still slow, follow the rest of the methods of fixing the slow connection.

Move the Router and Check Frequency

As previously said, if a housing area is larger than the router coverage, your computer may be unable to connect. Moving it closer to your computer or upgrading your router’s antennas is preferable.

Moreover, many apps are available in the AppStore to check frequencies these days. It will assist you in determining your internet speed in different areas of your home.

Use WiFi Extenders to Avoid Slow Internet

If the problem is with your computer, you can use extenders to improve your internet connection. But an extender will make no difference if the internet speed is slower than the WiFi speed.

Choose a Faster VPN for the Computer

It all ultimately comes down to finding the best VPN and using it. A faster VPN can improve your internet connection while also allowing you to visit websites while maintaining your anonymity. You can accomplish this by rerouting your internet traffic through a secure server.

Regular Computer Maintenance

The hard disk’s speed along with other parts impacts how well the computer performs. The computer’s performance is usually determined by the overall performance, although the speed of the hard drive varies as well. In many circumstances, however, the size of the hard disk is irrelevant.

Keeping your drive free of junk files, safe internet browsing, and keeping your PC free from overheating impact on how well the computer performs. So, make sure you do all that for better performance, hence better internet connectivity.

These methods require the slightest knowledge to fix slow internet. The internet problem is slow on one computer but quick on another can be simply solved.

The Significance of Certain Routers

It’s critical to understand that some routers might cause your internet to slow down since they promote data transfer between your devices and other networks. Many websites provide internet speed tests, which you may use to evaluate your router’s speed.

However, I will present you with a few top-of-the-line routers that will provide you with the fastest internet speed possible under any circumstance.

TP-Link Archer AX50

The most appealing feature of this router is that it reduces latency for all devices and apps while also providing coverage of up to 2000 square feet. It has four antennas and is compatible with a wide range of devices. This router has the advantage of being incredibly cost-effective.


This router contains a built-in software scan for viruses, distinguishing it from the competition. It protects linked devices from various online security dangers, making your computer’s internet connection fast. However, the sole disadvantage of this router is that it is pretty pricey.

 ➔ Netgear XR500 Nighthawk Pro

This router is ideal for gamers that demand a high-speed internet connection. It also features four antennas and the option of LED lighting. The router’s appearance and internet supply are highly appealing, but it is also costly, making it challenging for everyone to afford and use. However, I can assure you that it is well worth the price.

ASUS ROG Rapture GT AX11000

This router is the world’s first 10 Gigabit WiFi router, which speeds up gaming traffic from device to game server at every stage. It has eight antennae and protects your network from online dangers before they reach your network. This ensures that you will get an average of 80% WiFi range.

Nest WiFi

This is an excellent tiny router to have if you like small routers. It is inexpensive and may simply fit into your home without taking up too much room. The signals are strong enough to provide internet. Thus, they are well worth purchasing. It even comes with a built-in Google Home speaker, which adds to its attractiveness.

Online Frauds Can Infect and Cause the Internet to Slow Down

I’m sure you have heard stories from friends and family, or maybe experienced it yourself. This happens often due to visiting a website or accidentally visiting a page that caused your entire system to crash. These websites are regarded as online frauds because they infect your computer with viruses, slow down your internet, and hack your personal information.

Websites That Offer Free Trials

Scammers create these websites to advertise a free product, with the only cost being the shipping fee. People are unaware that these websites collect credit card information and charge them far more than what is mentioned since they click the “I Agree” button without reading the extremely long clause.

“Click and Win the Prize” Websites

We’ve all come across such sites at some point in our lives. These draw our attention to the fact that we will obtain spectacular presents that may be limited by just visiting the websites.

The fact is that there is no such thing as gifts in this world. These quickly hijack your computer and may even hack your personal information, thus exposing you to danger.

Downloading From Untrustworthy Websites

In the technological world, there is no such thing as free software. When you download free software, you inadvertently pay the price by allowing malware to infiltrate your machine. Your internet speed will ultimately suffer as a result of this. Always be wary of free software offerings and avoid downloading them if at all possible.

CPU Components Can Cause Your Internet to Slow Down

There are a few issues with your CPU that can significantly impact the speed of your internet. A low-end CPU coupled with a high-end gadget will be unable to keep up with workload demands, causing your computer and internet to slow down.

To address such a problem, you must first determine whether the issue is with your GPU or installed software. Installing free software has the largest risk of causing difficulties since it sends viruses to your computer, slowing it down.

Other primary factors might include a lack of storage space on your computer or outdated technology. There are simple remedies for these situations. For the former, all you have to do is delete or back up the data or programs you don’t need in your Google Drive or cloud.

An old hard drive is as good as dead in this case, so always consider purchasing a new one. It’s preferable to be safe than sorry.
