Have you ever been in an online meeting, playing a game, or watching a video when your internet connection suddenly starts lagging? Even though your WiFi signal appears strong and your internet speed seems fast enough, the connection still feels unstable.
The problem might not be your internet speed but rather packet loss.
Packet loss occurs when some of the data sent across a network fails to reach its destination. As a result, your connection may become unstable, video calls may stutter, websites may be difficult to access, and online games may experience lag.
This issue is relatively common in home networks, offices, villas, and businesses that rely on internet services in Bali. So, what causes packet loss, and how can you fix it?
What Is Packet Loss?
When we access the internet, data is not transmitted all at once as one large block. Instead, it is divided into small units called packets, which travel across the network to reach a server or destination device.
Ideally, all packets should arrive successfully. However, under certain conditions, some packets may be delayed, corrupted, or fail to arrive altogether.
This is known as packet loss.
For example, during a video call, audio and video are continuously transmitted as data packets. If some packets are lost along the way, the audio may sound choppy or the video may suddenly freeze.
Packet loss is usually expressed as a percentage. The higher the percentage, the more likely users are to experience network disruptions.
How Does Packet Loss Affect Your Internet Connection?
Packet loss does not always mean your internet connection has completely stopped working. Instead, it often appears as an unusual or inconsistent connection. Common symptoms include:
- Video calls frequently freeze or have choppy audio.
- Streaming videos suddenly buffer.
- Websites take longer to load.
- Online games experience lag or unresponsive character movements.
- File downloads or uploads fail.
- Remote desktop connections disconnect unexpectedly.
- Applications take longer to respond.
- WiFi feels slow even when speed test results appear normal.
For this reason, running a speed test alone may not be enough to determine the overall condition of your network.
What Causes Internet Packet Loss?
Several factors can cause packet loss. The source of the problem may lie with the user's device, local network, or internet service provider.
1. Weak WiFi Signal
One of the most common causes is poor WiFi connection quality.
Devices that are too far from the router, thick walls, multiple floors, and physical obstacles can weaken WiFi signals. Under certain conditions, data packets transmitted over a wireless connection may be disrupted, preventing some data from reaching its destination successfully.
For homes, villas, or offices with large floor areas, installing additional access points can help provide more consistent WiFi coverage.
2. Too Many Connected Devices
Routers have limited capacity to handle connected devices and network traffic.
When too many devices use the network simultaneously, available bandwidth can become insufficient. This becomes more noticeable when several devices perform bandwidth-intensive activities, such as high-resolution video streaming, cloud backups, large file downloads, or online gaming.
In Bali, WiFi networks shared by multiple guests, such as those in villas or guesthouses, require effective bandwidth management to maintain a reliable connection.
3. Insufficient Bandwidth
Packet loss can also occur when network traffic exceeds the available connection capacity.
For example, a network may be used for several activities at once:
- Video conferencing
- Video streaming
- Cloud-based CCTV
- File uploads
- Web browsing
- Large file downloads
If the internet capacity cannot keep up with demand, network congestion may occur and contribute to packet loss.
4. Router or Network Equipment Issues
Routers, modems, switches, access points, and other networking equipment can also be sources of problems.
Devices that have been in use for too long, overheating equipment, outdated firmware, or incorrect configurations can cause an unstable connection.
Restarting the router may sometimes help. However, if the problem keeps recurring, further investigation is recommended.
5. Wireless Network Interference
WiFi uses radio frequencies that can experience interference from other networks or electronic devices.
In densely populated areas, such as apartments, residential complexes, hotels, and commercial districts, multiple WiFi networks may use the same or overlapping channels.
As a result, wireless connections can become more susceptible to interference and packet loss.
Choosing the right WiFi channel and properly configuring access points can help reduce these issues.
6. Problems with the Internet Route or Service Provider
Not all packet loss originates from WiFi or devices within your home or office.
Disruptions can also occur along the network path between the customer and the internet service provider, or in the routing path to a specific server.
For example, your connection may work normally when accessing local websites but experience packet loss when connecting to servers in other locations.
If the problem persists even when using an Ethernet cable, the source of the disruption may need to be investigated on the provider's network.
How to Check for Packet Loss
One simple way to identify packet loss is by using the ping command.
On Windows, open Command Prompt and run the following command:
ping 8.8.8.8 -t
On Linux and macOS devices, you can also use the ping command through Terminal.
If you see messages such as Request timed out or a packet loss percentage in the test results, it may indicate that some packets failed to reach their destination.
However, ping results should be evaluated as a whole. One or two failed packets do not necessarily indicate a serious problem. Testing should be performed multiple times and against different destinations to determine whether the issue originates from the local network, internet connection, or a specific server.
For business networks, a network technician should ideally perform a more detailed assessment to identify the source of the problem accurately.
How to Fix Packet Loss
The right solution depends on the underlying cause of packet loss. Here are several steps you can try.
Check Your Router Placement
Place your router in an open location, preferably near the center of the area that requires WiFi coverage.
Avoid placing it inside cabinets, behind large objects, or too close to electronic devices that may cause interference.
Reduce Network Traffic
Check which devices are consuming large amounts of bandwidth. If necessary, limit downloads, streaming, or backup activities during peak hours.
For businesses, bandwidth management or Quality of Service (QoS) can help prioritize more important activities, such as video conferences and business-critical applications.
Use an Ethernet Cable for Important Devices
For devices such as office computers, smart TVs, CCTV systems, and work equipment that require a stable connection, an Ethernet cable is generally more consistent than WiFi.
Wired connections can also help reduce the load on the wireless network.
Check Your Router and Access Points
Make sure your network equipment is properly configured and that its firmware is up to date and still supported by the manufacturer.
If the network serves many users, consider using networking equipment specifically designed to handle that number of connected devices and the associated traffic.
Contact Your Internet Service Provider
If packet loss continues after checking your local network, contact your internet service provider.
Provide details about when the disruption occurs, which devices are affected, and any available ping test results. This information can help technicians investigate the issue across the provider's network.
