Does your network connection seem slower than usual? This can be caused by problems with your modem, router, Wi-Fi signal, slow DNS server, or even devices on your network that are overloading your bandwidth.
While these are the most common problems that you can think of whenever you have a slow network connection, one hidden problem that you won’t notice right away is packet loss.
This typically reduces the bandwidth or speed of the connection, sometimes resulting in poor quality protocols or latency-sensitive applications such as VoIP or video streaming.
Packet loss is a critical metric for network performance and should never occur on your network at the same time. We’re going to find out what packet loss is, what causes it, how to detect it, and how to fix packet loss.
What is packet loss?
Information is transmitted over the network as a series of discrete units, commonly called packets.
When connected together in the correct order, these individual blocks form a coherent whole and the network connection works fine. However, sometimes packets may arrive incomplete, incorrect or corrupted, making them useless, but if they are lost, the network connection is broken.

In simple terms, packet loss is the loss of data during a specific transfer, resulting in a slower-than-normal connection and decreased reliability of communication between your network and local and remote devices. It can also affect your CPU utilization, increasing it to handle additional network overhead.
Most networks experience low packet loss from time to time because network connections differ so that packets will inevitably be dropped from time to time.
Ideally, however, networks should not be dropping packets. This is rare on properly functioning networks, but almost every ISP suffers or suffers from packet loss. It is also more common with wireless than wired.
What causes packet loss?
Data is transmitted in packets that are sent over the network at regular intervals. When these packets do not reach their destination, the sender receives an echo request to notify them that it was unsuccessful.
It is normal to receive one or two of these losses, but if the problem gets worse with more and more packet losses, there will be more postbacks, eventually overloading the transmission line, and you may experience a data transmission timeout. / p>
There are several reasons for packet loss on your network connection. Among them:
- Inefficiency or failure of a component that transmits data over the network, such as an unreliable cable connection, a faulty router, or a poor WiFi signal.
- High latency, which causes difficulties in sequential delivery of data packets.
- The interval between delivered packets, causing a synchronization problem at the destination.
- Insufficient bandwidth or inability to optimize existing bandwidth.
- Faulty software, which may contain many bugs.
- Old transfer points are used for data transfer.
- Damaged, improperly connected, or slow cables that may “leak” packets.
- Hardware and physical infrastructure are not optimal for data transmission or may be damaged or have errors.
- The wireless network may be affected by elements such as distance, thick walls, or other interference from nearby wireless networks.
It can also be intentional, for example, when there is high network congestion, packet loss can be used to limit bandwidth during video streams to avoid delays, or during VoIP calls. The result is calls or streams of poor quality, which in turn affects the user experience.
To find out the root cause of packet loss, you need to first find it and then work backwards to fix it. This could signal the vulnerability of your network, especially to hacker attacks, or expose you to risks that could attract cybercriminals to take and take your security system hostage.
All of this happens when packet loss levels exceed the allowable rate of 1-2 percent of the total packet flow. Anything above has a significant impact on quality.
Your network administrator can check to see if the packet loss is 0 percent, and if it starts to increase, check with your ISP to determine the root cause.

How to fix packet loss issues on your network connection
1. Determine the reason for the packet loss
2. Replace problem equipment
3. Correct software bugs or inform vendor (if third party)
4. Use a network monitoring tool
Determine the reason for packet loss
To figure out the root cause of packet loss on your network, you need to check some things first, such as the Ethernet connection between your devices, any improper connections or physical signs of damage, the cables are working properly, and checking your switches and router or modem.
Determine if your network has enough bandwidth to handle the required devices, and if there is any equipment processing more than it should. It is a matter of searching until you find and replace anything that is not working as expected until the problem is resolved.
You can also use a good router or switch and replace the problematic hardware on your network to see if it fixes packet loss.
There are software applications that can be used to detect packet loss on a network. These programs listen for packets by looking at them or analyzing their transit time. However, you can also check connectivity with devices on your network to see if packet loss exists.
More advanced packet loss detection tools are available, but once you learn how to check network connections, all you have to do is isolate and fix to determine the cause and source of the problem.
Replace problem hardware
Now that you know the root cause of packet loss on your network connection, you can do two things to fix this packet loss: replace the problematic hardware.
Isolation and remediation steps will help you find out the source and cause of packet loss, depending on the equipment causing it, from devices on your network.
Correct any software bugs or report to supplier (third – Batch)
You can fix the software bugs yourself or, if you are using a third-party program, report it to the vendor for support and a possible fix.
Use a network monitoring tool
Closely coupled networks with better connections and routers experience almost no packet loss. However, not everything that happens on the Internet is known along the way, so packet loss should be expected.
The good news is that you can use network monitoring tools that can help you identify hardware-induced packet loss while offering continuous monitoring of your devices to prevent the problem.
One of the best network monitoring tools on the market is SolarWinds Network Performance Monitor. It runs on Windows Server and is a comprehensive network health checker that uses SNMP for real-time monitoring.
The tool displays your network so you can see any signs of packet loss and identify its source. It has an auto-discovery feature that constantly displays your network, creating a list of devices on it, a network map, and any network changes.
It also monitors the performance of virtual machine systems and wireless devices by collecting SNMP messages that report all alerts on all devices on your network. Ultimately, this helps prevent excess bandwidth that can lead to packet loss.
Packet Loss Prevention
Depending on the root cause of packet loss, you can choose any of the above methods to solve the packet loss problem on your network connection.
If it is a hardware issue, replace it with a new one that might fix the problem, but if your network is congested, you can increase your bandwidth or use a QoS solution to prioritize real-time network traffic.
Simple ways to manage packet loss include checking that your ports and cables are properly connected and installed, and that you are using cable connections if you want to improve the quality of your connection. Eliminate any interference with wireless connections and keep your devices and software up to date.
