How To Fix Upload Packet Loss? (Complete Guide)

Packet loss is one of the issues related to data transmission and uploading. It refers to the loss of data that travels in the form of packets across the network.

Higher packet loss is generally associated with slow upload speeds, low-quality downloads, and poor user experience.

However, by following the ideal methods, the packet loss can be reduced to a minimum to boost productivity and yield better results. 

In this article, we will learn about the causes that lead to upload packet loss and ways to fix them. 

So, without keeping much suspense, let us jump right into the article. 

Causes Of Upload Packet Loss

1. Overloaded Network Devices

One of the common issues that lead to significant packet loss is the overload of network devices.

Most users rely on routers for internet connection. Sometimes the routers are infused with traffic, which prevents faster upload speeds owing to packet loss. 

2. Faulty Equipment And Cabling

Fault or broken equipment or cables can contribute to lowering the upload speeds related to data transmission, which enhances the packet loss, hindering the overall user experience.

Thus, ensure using ethernet cables or modems without any damage to them.

3. Bandwidth Congestion

Sometimes the bandwidth capabilities are unable to handle the volume of data uploaded by the user resulting in congestion or packet loss. 

4. Faulty Or Insufficient Hardware

The use of outdated machinery or hardware for uploading, such as worn-out network interface cards (NIC) or adapters contributes to increasing the packet loss resulting in slower speeds and performance. 

5. Software Issues

Sofware issues constitute the use of outdated network drivers, inaccurate networking settings, and other interferences that slow down the uploading speeds through excessive packet loss.

6. Wi-fi Networks

Wireless networks such as Wi-Fi are most prone to packet loss that hinders the user experience.

Network interferences from other nearby connections or connecting to multiple networks can lead to such issues. 

7. Network Attacks

DOS or Denial of service attacks contributes to slower uploading speeds or increased packed loss that affects the performance of the internet connection.

Such malicious activities intend to harm the networking services by overloading the devices with traffic. 

8. Deficient Infrastructure

The use of outdated or deficient infrastructure to carry out networking needs can lead to packet loss that affects the upload performance and disrupts the user experience. 

How To Fix Upload Packet Loss?

A Packet Loss Test checks how many packets are sent from the network to a destination and how many actually arrive. If more packets are sent than received, it means there is packet loss.

Below we have discussed some popular ways to fix the upload packet loss to improve productivity. 

1. Restarting Devices

Restart all the networking devices used in the connection, such as a modem, or router by disconnecting the cables or restarting them using the power switch. 

Once reset, set up the internet connection again and test the speeds to check if the packet loss has been reduced or not. 

2. Check The Cable Connection

If you are using LAN or Ethernet cables for connecting to the internet, ensure that the cables are not faulty or damaged as such cables can lead to further packet loss. 

If any fault in the cables has been discovered, switch to a newer cable without any damage to resolve the packet loss issue. 

3. Check Wi-fi Connection

In case of a Wireless Wi-fi connection, users must check for the positioning of the router. 

Make sure to place the router near the system for better connectivity and update the networking drivers to their latest versions. 

It is also observed that wired connections account for lower packet loss. Thus, you can also consider switching to a wired connection for better performance and results. 

To check for Wi-fi connectivity, head to the settings menu followed by the Network tab. 

Under the list of available options, Select WiFi and enable it to connect to the existing network. 

4. Resetting Network Settings

Follow the steps to reset the network settings to fix the upload packet loss issue. 

  1. Navigate to System Settings using the Windows tab, followed by Network and Internet Settings.
  2. Head towards the Advanced section and proceed by clicking on Network Reset to use the default settings for connectivity. 

5. Adjusting Packet Size

Adjusting the packet size to smaller fragments allows you to improve the network performance and reduce upload packet loss. Follow the given steps to adjust the packet size settings. 

  1. Navigate to the Start menu and search for View Network Connections, followed by your network adapter. 
  2. Under the adapter settings, head towards the Properties and configure the settings. 
  3. Under the Advanced tab, locate the Jumbo Frame property and adjust the value accordingly to lower the packet loss. 
  4. It is advisable to adjust values to 8 KB or lower to improve the network performance. 

6. Configuring Quality Of Service (QoS) Settings

Quality of service settings allows users to give preference to various applications demanding higher internet speeds by improving the bandwidth performance. Follow the given steps to configure the QoS settings. 

  1. Navigate to any browser and enter the default IP address of your router located beneath the device to log in. 
  2. Under the wireless tab, head toward the QoS settings and prioritize the applications for better connectivity. 
  3. You can also add specific networks to priority to reduce upload packet loss. Save and apply the changes to fix the issue. 

7. Upgrading Hardware And Software

One of the best ways to reduce packet loss is by upgrading from outdated networking devices to faster hardware components. 

It is also vital to ensure that the networking drivers are updated regularly to their latest versions to avoid any issues and boost performance leading to a better experience. 

How To Prevent Packet Loss?

1. Implementing Proactive Measures

Users must customize their networking settings to yield better results. Furthermore, it is also recommended to update your network security measures for reducing packet loss and improving safety. 

2. Maintaining Network Infrastructure

The use of outdated networking infrastructure or devices can contribute to poor performance hindering the user experience.

Thus, for optimal results, ensure that no damaged cables are used for data transmission and replace any faulty modems or routers.

3. Regularly Monitoring Network Performance

To monitor the performance to keep track of packet loss, there are various online tools available that can help you improve the overall performance during internet surfing.

You can also keep track of the packet loss by accessing the logs related to connection patterns. 


What Is The Difference Between Upload And Download Packet Loss?

Upload packet loss refers to the mishandling or loss of data during transmission from your system to the Internet. On the contrary, download packet loss refers to data loss during the transmission of information or files from the internet to the system. 

What Can Cause Intermittent Packet Loss?

Interference from other networking devices and bandwidth traffic overload are common causes that lead to Intermittent packet loss. 

How Can I Test For Packet Loss On A Mobile Device?

To test for packet loss on your mobile device, users can rely on various network diagnosing tools available that help analyze the packet loss patterns. 

What Is The Impact Of Packet Loss On VoIP Calls?

Packet loss affects VoIP (Voice over Internet Protocol Calls) by degrading the audio quality that hinders the user experience. Sometimes the audio is distorted or cannot be heard due to such issues. 

Can Packet Loss Affect Online Gaming Performance?

Yes, a significant packet loss can cause problems with your gaming experience as it leads to delayed response times, lag, or unstable movements. 


This was everything you needed to know about upload Packet loss. While most of the issues are software related and can be resolved by following the above-discussed steps, broken or faulty hardware issues will require you to switch your networking devices for a better experience.
