Internet Slow On PC But Fast on Other Devices

While your smartphone and tablet may offer blazing-fast connectivity, you may notice that your PC needs to catch up, causing disrupted workflows and streaming hiccups. The issue of the internet slow on PC but fast on other devices is a common yet perplexing problem many users encounter.

One of the leading culprits behind this issue is outdated network drivers. They can create a bottleneck that prevents your computer from utilizing your internet's full speed.

In contrast, your other gadgets, which may have updated network components, face no such issues. The good news is that updating your network drivers often offers a simple yet effective fix for restoring your PC to optimal internet performance.

By taking this step, you can bring harmony back to your device ecosystem and enjoy consistent speeds across the board. It would be best to read through the following article to learn more about your PC's slow inter issue.

What is Internet Latency?

Internet latency refers to the delay in transmitting data over the network. It's typically measured in milliseconds and plays a crucial role in determining the quality of your online experience.

What is Internet Latency

The time it takes for a packet of data to travel from your computer to a server and back is known as “ping” time. It's a vital aspect of internet latency. This measurement is usually done in milliseconds.

High latency can cause noticeable delays in various online activities. For instance, web pages may load slowly, or online video may buffer. In extreme cases, high latency can make some online services practically unusable.

However, latency isn't solely dependent on your internet speed. The distance between your internet device and the server, plus the number of hops it takes to get there, also impacts this delay. Networking hardware and settings can additionally influence latency.

Reducing latency can improve the quality of video conferencing, gaming, and other real-time online activities. Various tools and strategies can be used for this purpose. Upgrading your hardware or using wired connections can often yield better results.

Internet latency is an essential parameter in your online experience. It impacts the speed and quality of data transfer. Understanding and optimizing it can vastly improve your internet usability.

Possible Causes of Slow Internet on PC

Slow internet on a PC can disrupt your workflow, hinder your entertainment, and generally make your online experience less enjoyable. While other devices may run smoothly, various factors can contribute to your PC's sluggish performance.

Possible Causes of Slow Internet on PC

Outdated Network Drivers

Your network drivers act as a bridge between your computer's operating system and the hardware. Outdated drivers may lack essential updates, affecting the overall speed and reliability of your internet connection.

Background Applications

Certain background applications can hog your internet bandwidth without your knowledge. This can slow down your internet connection significantly when you're actively using it.

Limited Hardware Capabilities

Your computer's hardware also plays a significant role in your internet speed. Older models may lack the processing speed or memory to handle faster connections effectively.

Malware and Viruses

Invasive software like malware or viruses can use your bandwidth and slow down your system. They might run processes you're unaware of, affecting speed and security.

Incorrect Settings

Sometimes, the problem is as simple as incorrect network settings. Your DNS configurations or TCP/IP settings might not be optimized for speed.

Internet Slow On PC But Fast on Other Devices-How to Fix it?

Addressing slow internet on a PC involves identifying the root cause and implementing the right solution. Below are possible solutions for each of the causes you've mentioned:

Internet Slow On PC But Fast on Other Devices

Outdated Network Drivers

Solution: Update your network drivers to the latest version.

  • Windows:
    1. Open Device Manager by right-clicking the Start button and selecting it.
    2. Locate “Network adapters” and expand it.
    3. Right-click your network adapter and choose “Update driver.”
    4. Follow the on-screen instructions.
  • macOS: Apple usually includes driver updates in system updates. Go to “Apple Menu > System Preferences > Software Update” to check for updates.

Background Applications

Solution: Close unnecessary background applications or limit their bandwidth usage.

  • Use Task Manager on Windows (Ctrl+Shift+Esc) or Activity Monitor on macOS (found in /Applications/Utilities/) to identify which applications are using the most resources and close them if they are not needed.
  • Some applications allow you to limit their bandwidth usage in their settings.
  • Consider using a network monitor tool to better understand which apps are using the most bandwidth.

Limited Hardware Capabilities

Solution: Upgrade hardware or optimize settings.

  • Upgrade your RAM or consider investing in a better Network Interface Card (NIC) for improved performance.
  • Use lightweight browsers and disable unnecessary extensions or plugins.
  • Ensure that your hardware meets the minimum requirements for your most frequently used applications.

Malware and Viruses

Solution: Run a thorough malware and antivirus scan.

  • Use reputable antivirus software to scan and remove any threats.
  • Also consider using specialized anti-malware software for a more comprehensive scan.
  • Keep your security software up-to-date to protect against future threats.

Incorrect Settings

Solution: Correct network settings for optimal performance.

  • DNS Settings: Consider using faster DNS servers like Google's ( and or Cloudflare's ( and
  • TCP/IP Settings:
    1. On Windows, you can reset the TCP/IP stack by opening Command Prompt as an administrator and running Netsh int IP reset.
    2. On macOS, you can renew the DHCP lease via “System Preferences > Network > Advanced > TCP/IP > Renew DHCP Lease.”
  • Router Settings:
    1. Ensure your router's firmware is up-to-date.
    2. Optimize settings for performance (e.g., select the best channel and enable QoS if available).

By systematically addressing each of these factors, you're likely to find the root cause and can take steps to improve your PC's internet performance.

Bottom Lines

When you're grappling with the frustration of an underperforming online experience, it's essential to pinpoint the issue accurately. If you find the internet slow on PC but fast on other devices, it indicates that the problem likely resides with your computer rather than your network.

Your PC may suffer from outdated network drivers, bandwidth-hogging background apps, or even malware. This can make even simple tasks like browsing or streaming a nightmare, hindering productivity and enjoyment.

Fortunately, remedies are often straightforward. By methodically addressing these factors, you can optimize your PC's internet performance and align it with the faster speeds you're experiencing on other devices.
