A common mistake many of you make is overlooking network congestion’s role in causing upload packet loss.

Network congestion is akin to a traffic jam of data on your network—too many packets trying to move along the same path at once can lead to some packets “losing their way” or being discarded altogether. This results in upload packet loss, resulting in slower upload speeds, interruptions, and poor network performance.

How do you manage and prevent this? The simplest solution is often to reduce the network’s traffic. Here are a few tips:

  1. Limit Bandwidth Usage: Moderate the number of high-bandwidth activities run simultaneously on your network. This could include file uploads, video streaming, online gaming, or video calls.
  2. Optimize Peak Usage Times: Schedule heavy data usage tasks for off-peak times when fewer users are likely to be active on the network.
  3. Use QoS Settings: Quality of Service (QoS) settings in your router can prioritize certain traffic over others. For instance, if video calls are crucial to your work, you can prioritize those over other data types.
  4. Upgrade Your Internet Plan: If the demand for data on your network is high, it may be time to consider upgrading your Internet plan to offer higher bandwidth.

These steps allow you to manage your network effectively, reduce congestion, and minimize upload packet loss.

Remember, a less congested network leads to smoother sailing for your data packets.

Mistake 2 – Using Outdated Routers and Modems

Utilizing outdated hardware is another common mistake that often gets overlooked. Old or obsolete routers and modems may not be capable of handling today’s high-speed internet connections effectively.

Packet loss can occur if your hardware can’t keep up with the data speeds your internet service provides. Similarly, outdated hardware may lack the requisite technologies for effective packet handling, thus hampering performance.

Here are some tips on maintaining your hardware to prevent packet loss:

  1. Regular Hardware Checkups: Like your car, your network hardware needs maintenance. Carry out regular performance checkups to ensure they’re functioning optimally.
  2. Install Firmware Updates: Keep your modem or router firmware up-to-date. These updates often contain patches for bugs that could be contributing to packet loss.
  3. Upgrade Outdated Hardware: If your hardware is old or cannot support the speed of your internet connection, consider replacing it with a more recent model.

By maintaining up-to-date and functioning hardware, you are ensuring the overall health of your network, driving down upload packet loss rates, and improving your internet usage experience significantly.

Mistake 3 – Overlooking Firewall and Security Settings

In the effort to secure our network, you overlook the firewall and security settings on packet transmission.

While firewall settings are implemented to protect the network from potential threats, some aggressive configurations can inadvertently block or delay data packets, resulting in packet loss.

Here are some guidelines to tweak these settings without compromising your network’s security:

  1. Review Your Firewall Settings: Check your firewall’s security levels. If you are experiencing packet loss and suspect the firewall might be the cause, try to decrease the security level or switch to a setup that allows for better data packet transmission.
  2. Inspect Security Software Settings: Check its settings if you have security software like antivirus or anti-malware installed. Some security software might monitor your network traffic and delay or block certain packets. Customize these settings to avoid network interference while still ensuring protection.
  3. VPN Consideration: If you’re using a VPN, be aware it might also contribute to packet loss. Try switching servers or temporarily disabling the VPN to identify if it’s the cause.

By thoroughly examining and aptly configuring your network’s security settings, you maintain a robust defense against threats and optimize data transmission, reducing the odds of upload packet loss and enhancing your internet experience.

Mistake 4 – Not Considering Software Updates

Just as hardware plays a vital role in network performance, so does the software running on that hardware.

Ignoring software updates can lead to situations where the software becomes outdated, resulting in impaired network performance and even packet loss.

Outdated software might have undiscovered bugs, compatibility issues, or lack the necessary optimization and enhancements found in their updated versions – making them less efficient at managing data traffic and directly contributing to upload packet loss.

Regularly updating your network software helps mitigate these issues by providing bug fixes, new features, performance improvements, and enhanced capabilities for managing network traffic. This helps improve overall network performance and significantly reduces the likelihood of incidents leading to packet loss.

Mistake 5 – Neglecting Packet Loss in Video Conferences and Online Gaming

Packet loss can significantly impact real-time online activities, and it’s a mistake to neglect it, especially in video conferencing and online gaming.

Data transmission happens in real-time in these scenarios, meaning every packet counts.

When packets are lost, it could result in stuttering sound, low-quality or frozen images, lag in video games, and even dropped connections.

Addressing this issue can greatly enhance the quality of these experiences, leading to smoother gameplay and clearer communication during video conferences. Here are some potential solutions:

  1. Wired Connection.
  2. Close Unnecessary Applications.
  3. Configure QoS Settings: As mentioned before, you can configure Quality of Service (QoS) settings in your router to prioritize certain types of traffic. For instance, gaming and video conferencing can be assigned a higher priority.
  4. Use a Gaming VPN.

Mistake 6 – Failing to Identify External Factors


Sometimes, the root of upload packet loss lies outside your immediate network, and it is a mistake to overlook external factors like Internet Service Provider (ISP) issues or physical barriers.

  • ISP Issues: Your ISP plays a pivotal role in your internet experience. Any congestion, technical issues, or faults in the ISP’s network can lead to packet loss. Similarly, issues at the ISP level might constrain your internet speed, resulting in packet loss if the data rate exceeds the available bandwidth.
  • Physical Barriers: Physical barriers can significantly impact wireless signals. Things like walls, electronic appliances, and even underwater cables can weaken the signal, leading to intermittent connections and packet loss.

To handle these issues, here are some potential solutions:

  1. Contact your ISP.
  2. Consider a Different ISP.
  3. Optimize Wi-Fi Signals.
  4. Switch to Wired.

Mistake 7 – Unwarranted Multitasking

You consume bandwidth whenever you open another browser tab, stream another video, or launch another online game. If these demands outpace the available bandwidth, packet loss can occur as the network struggles to accommodate all the data streams.

Here are a few tips to effectively manage your tasks and reduce the chances of packet loss:

  1. Prioritize Tasks.
  2. Limit the Number of Running Applications.
  3. Schedule Updates Appropriately.
  4. Use QoS.

By effectively managing your tasks and resources, you can reduce network strain, prevent upload packet loss, and ensure a smoother and more efficient internet experience.


Upload packet loss can negatively impact your overall network performance, leading to frustrations from choppy video calls to laggy gaming experiences. Avoiding these seven common mistakes can substantially reduce packet loss and enhance your internet experience:
