What are causes of why is internet slow on only one computer?

Hardware Problems:

In addition to the software problems mentioned above, you might experience particular hardware problems that result in a slow internet connection. To determine if the computer hardware causes the connection problem, you must start your computer in Safe Mode. If a hardware issue arises, the best course of action is to contact a specialist or start troubleshooting.

Changing the Frequency:

Most modern routers include multiple bands, typically 2.4GHz and 5GHz, while some high-end versions also offer an additional 5GHz band. Use the 5GHz frequency if you want a quick and strong signal and your device is near to the router. For a device placed in a more remote area, the 2.4GHz band is more advantageous.

Background-Running Apps:

On occasion, when using the computer, you may not be aware of some apps or programs operating in the background. These applications and programs can consume a lot of memory and disk space, competing with your web browser and slowing down your internet connection. Your internet connection may experience significant speed and stability loss as a result.

In this circumstance, you can look for problematic background apps and programs. Find the programs using a lot of internet bandwidth in the Task Manager and disable them. This will give your browser more leeway in how it can use RAM to provide a flawless internet experience.


A VPN can use a remote server to provide a secure connection with encrypted communication, but it might also reduce your internet speed. In contrast to the free alternative, a premium VPN offers a better deal with a somewhat quicker connection. To speed up signal transmission, it also helps to connect to a server that is close by.

Virus and Spyware Attacks:

Two of the most harmful pieces of software in the modern internet environment are computer viruses and spyware. Your internet speed will drop due to their attack and many additional interruptions to your PC. Possibly worse, you can even completely lose your internet connection.

You should install the many anti-virus and anti-spyware products available on the market. Although a free version is usable, it almost certainly isn’t sufficient to safeguard your machine. A premium application will provide a strong defence against nefarious assaults from such destructive viruses and spyware.

Computer’s Position:

A poor Wi-Fi signal is most likely the cause of a slow internet speed. In general, your ISP’s modem and router won’t function as efficiently as you might anticipate them to, and they won’t distribute Wi-Fi signals across the complete house. There might also be intermittent dead zones. Obstacles like thick walls and flooring make the issue worse.

If you can still manage with the conventional setup, try moving your computer closer to the router because the Wi-Fi signal will be stronger and faster the closer the distance between your computer and the router. Additionally, make an effort to avoid obstructions to prevent the signal from passing through too many walls or dividers.

Other electronic gadgets that could use the same frequency as your computer or network include microwaves, smart TVs, security cameras, and many more. Moving them out of your Wi-Fi signals’ paths could improve the flow of traffic to your device.

Alternately, swap off the default ISP router for a better one. Even though you might have to invest a considerable sum of money, it will be worthwhile because you won’t have to continue paying monthly equipment fees. Another wise choice for enhancing the signal strength is to spend money on a high-quality Wi-Fi extender.

Additionally, you might think about investing in a mesh Wi-Fi system, which would ensure a more consistent and extensive coverage area without having to worry about dead patches.

Frequently Asked Questions

Why is my internet speed different on different computers?

Since the algorithms employed by the Speedtest.net website and Speedtest.net app are so comparable, the variations in speeds are most likely caused by one of the following external factors: variations in the bandwidth available: Make sure the tests don’t run concurrently; each test requires a dedicated portion of your capacity.

Why is my internet slow on my computer but not my phone?

Your laptop can be linked to a 2.4GHz channel rather than a 5GHz channel, which you might not have realized. However, you are ostensibly employing a dual-band router. Therefore, your laptop may use the 2.4GHz channel while your phone is connecting to the 5GHz frequency.

Why is my WiFi slow on my laptop only?

Your laptop’s WiFi is running slowly because it is too far from the router. Typically, WiFi can be hampered by walls, large objects, and other radio frequency-using items. Update your driver software and restore the factory default settings for your router if it doesn’t fix the issue.

Does Internet speed depend on the device?

Your network’s hardware, like the router or cable, has a big impact on how fast your internet may be. For instance, ethernet connections are typically faster and more reliable than WiFi connections. As additional devices join the same WiFi network, your internet speed may drop if you use that connection.
