When it comes to Zoom's performance and connection stability, network performance plays a crucial role. Zoom performance and connection issues can be caused by common network problems like jitter, packet loss and congestion. Which is why Network Monitoring is your biggest ally when monitoring Zoom performance and identifying connectivity issues.

Several factors related to network performance can impact your Zoom experience. Let's explore some of the key aspects to consider:

• Internet Bandwidth: Insufficient internet bandwidth is one of the primary culprits behind poor Zoom performance. Both upload and download speeds influence your ability to send and receive audio and video data smoothly. If your internet connection is slow or shared with multiple devices, it can lead to pixelated video, audio distortion, or even dropped calls.
• Network Congestion: Network congestion occurs when multiple users or devices compete for limited bandwidth simultaneously. During peak hours or in crowded networks, such as public Wi-Fi hotspots, network congestion can severely impact your Zoom connection. This can manifest as lag, jitter, or frozen video frames.
• Firewall and Proxy Settings: Sometimes, the settings on your firewall or proxy server can interfere with Zoom's connectivity. If certain ports or protocols used by Zoom are blocked, it can result in connection issues. Adjusting firewall settings or consulting with your network administrator might be necessary to ensure a stable Zoom connection.
• Wi-Fi Signal Strength: The strength and stability of your Wi-Fi signal are crucial for uninterrupted Zoom meetings. Weak Wi-Fi signals, especially if you are far from the router or obstructed by walls, can lead to intermittent connectivity problems, laggy video, or audio disruptions.
• Network Hardware: The quality and capabilities of your network hardware, such as routers and modems, can impact Zoom performance. Outdated or underpowered equipment might struggle to handle the demands of real-time video and audio streaming, resulting in connection drops or degraded performance.
• Network Quality of Service (QoS): Some routers and network setups offer Quality of Service (QoS) settings, allowing you to prioritize certain types of traffic, such as Zoom calls, over other activities on your network. Properly configuring QoS for VoIP especially can help ensure a smoother Zoom experience by giving priority to video and audio data.

Addressing these network performance factors can significantly enhance your Zoom experience. In the upcoming sections of this blog post, we'll delve deeper into each of these aspects and provide practical tips and solutions to troubleshoot network-related issues and optimize your Zoom connection stability.

To effectively identify Zoom performance issues, it's crucial to have a reliable method for monitoring both your network and Zoom performance. By continuously monitoring these aspects, you can proactively detect and address potential issues before they impact your Zoom experience. We recommend Obkio's Network Performance Monitoring tool.

Obkio is designed specifically for monitoring network performance and can be instrumental in identifying and diagnosing network-related problems that affect Zoom performance. It provides comprehensive insights into the performance of your network infrastructure, including latency, packet loss, and bandwidth utilization.

Additionally, Obkio's end-to-end monitoring ensures that you can monitor Zoom performance from the user perspective. It captures data from both ends of the connection, including your network infrastructure and the Zoom application itself. This holistic view allows you to determine whether performance issues originate from your network or Zoom's servers, enabling you to troubleshoot effectively and engage with relevant support teams, if necessary.

To begin monitoring Zoom network performance with Obkio, you need to deploy Monitoring Agents which continuously measure network and Zoom performance in key network locations.

In our previous article in our Zoom series, How to Monitor Network and Zoom Performance, we talk about setting up the Monitoring Agents, so you can refer to that article for setup.

Essentially, to collect the data you need to translate, you’ll need:

• 1 AWS Monitoring Agent: Since Zoom is supported by AWS, you’ll need the AWS Agent which monitors performance up to the AWS cloud. To learn how to find the AWS Data Center location used by your Zoom, check out our article on How to Identify the Zoom Data Center Location on AWS Infrastructure.
• 1 other Public Monitoring Agent: To compare performance up to the Internet and quickly identify if the problem is global or specific to Zoom. This will be great information for later in the troubleshooting process. You can use an Azure Agent or Google Cloud Agent.
• 1 Local Agent: Installed in the targeted office location experiencing the Zoom connectivity issues. There are several Agent types available (all with the same features), and they can be installed on MacOS, Windows, Linux and more.

Once your Monitoring Agents are deployed, they will continuously exchange synthetic UDP traffic between each other to monitor performance, this is called a Network Monitoring Session.

To identify Zoom issues, you’ll want to let the Agents run and collect data for some time. If you’re unlucky enough, you’ll see the performance issues after just a few minutes, but we recommend letting the Agents collect data for at least 3 hours.

Obkio's Network Response Time Graph and VoIP Quality Graph showing Latency, Jitter, and Packet Loss

When the Agents start exchanging traffic, they start monitoring and collecting performance data, which you can see on the Network Response Time Graph, such as:

• Latency: Latency refers to the time it takes for data to travel from the sender to the receiver. In Zoom, high latency can cause delays in audio and video synchronization, leading to a poor user experience. It is measured in milliseconds (ms), and lower latency values are desirable.
• Jitter: Jitter is the variation in the delay of packet arrival caused by network congestion, improper queuing, or other factors. In Zoom, high jitter can cause audio and video distortion, making it difficult to understand and follow the conversation. Jitter is measured in milliseconds (ms), and lower jitter values are better.
• Packet loss: Packet loss occurs when data packets are dropped or fail to reach their destination. In Zoom, packet loss can result in choppy audio or video, pixelation, or frozen screens. It is expressed as a percentage, and lower packet loss rates are preferred.
• VoIP Quality with MOS Score: VoIP Quality: VoIP (Voice over Internet Protocol) quality specifically focuses on the audio aspect of Zoom performance. It assesses the clarity, consistency, and reliability of voice communication during a video conference. Factors such as background noise, echo, distortion, and dropped audio packets can affect the overall VoIP quality. VoIP monitoring metrics helps ensure that participants can communicate effectively without experiencing audio-related issues.
• Bandwidth: Bandwidth is the amount of data that can be transmitted over a network connection in a given time. In Zoom, sufficient bandwidth is necessary to support high-quality audio and video streams. Insufficient bandwidth can result in degraded audio and video quality. Bandwidth is typically measured in bits per second (bps) or kilobits per second (Kbps).
• Network Congestion: Network congestion occurs when there is a high volume of traffic on a network, leading to reduced performance. In Zoom, network congestion can cause increased latency, packet loss, and jitter. Monitoring for signs of network congestion can help identify potential issues before they impact the user experience.
• Quality of Service (QoS): QoS refers to the ability to prioritize specific types of network traffic, such as Zoom video and audio packets, over other types of traffic. Implementing QoS mechanisms can help ensure that Zoom traffic is given priority, reducing the likelihood of performance issues.

By leveraging Obkio's monitoring capabilities, you gain real-time visibility into your network's performance, allowing you to detect any anomalies or bottlenecks that may impact your Zoom calls. Obkio collects and analyzes data, providing valuable metrics and reports to help you troubleshoot and optimize your network's performance specifically for Zoom.

At this point, if you're experiencing a Zoom performance or connectivity issue, you’ll be able to see it in Obkio's Network Response Time graphs. You can see moments of jitter, packet loss, and latency, and even the impact on MOS Score.

So we now know that poor network performance can affect Zoom performance, but what Zoom issues can it cause exactly? Let's go over some of the most common Zoom performance and connection issues that we'll be troubleshooting:

1. Lag and Delay: Insufficient network bandwidth or high network congestion can cause lag and delay during Zoom meetings. This results in delays between participants' audio and video streams, making conversations disjointed and difficult to follow.
2. Audio Distortion: Inadequate network performance can cause audio distortion, where voices become garbled or robotic. This can make it challenging to understand and communicate effectively during Zoom calls.
3. Video Freezing and Pixelation: When your network struggles to transmit video data efficiently, you may experience frequent video freezing or pixelation. This disrupts the visual quality of the meeting, making it harder to perceive facial expressions and non-verbal cues.
4. Poor Image and Video Quality: If your network is unable to provide sufficient bandwidth, Zoom may automatically reduce the image and video quality to compensate. This can result in blurry or pixelated visuals, making it difficult to view shared screens or presentations.
5. Inconsistent Screen Sharing: Network issues can also affect screen sharing capabilities in Zoom. Participants may encounter difficulties in sharing their screens or experience lag and delays when viewing shared content, hampering collaboration and productivity.

1. Dropped Calls: Unstable network connections can lead to frequent call drops, where participants get disconnected from the meeting unexpectedly. This interruption can disrupt the flow of discussions and cause frustration for all participants.
2. Limited Participant Capacity: In some cases, a weak network connection might limit the number of participants who can effectively join a Zoom meeting. If the network cannot handle the required bandwidth for multiple participants, it may result in connectivity issues or degraded performance.

These issues can significantly impact the effectiveness and productivity of your Zoom meetings. By addressing network performance problems and implementing appropriate solutions, you can mitigate these challenges and ensure a smoother and more reliable Zoom experience for yourself and all meeting participants.

To begin troubleshooting your Zoom issue, you need to first establish: Is it really a network problem?

When encountering a Zoom issue, it's important to determine whether the problem stems from a network-related issue or if it originates from another source. To effectively troubleshoot, you can begin by comparing monitoring sessions between the AWS Public Monitoring Agent and another Public Monitoring Agent you have deployed.

1. Establishing a Baseline: Start by establishing a baseline for normal network performance. Monitor the performance of both agents during typical usage periods when Zoom is functioning without any apparent issues. This baseline data serves as a reference point for comparison when troubleshooting Zoom problems later.
2. Capturing Performance Data: During a Zoom session experiencing issues, capture performance data simultaneously from both monitoring agents. This data should include metrics such as latency, packet loss, and bandwidth utilization. Comparing the data collected from the AWS Public Monitoring Agent and the other Public Monitoring Agent allows you to identify discrepancies and pinpoint potential network-related problems.
3. Analyzing the Data: Analyze the collected performance data to identify any patterns or anomalies that correlate with the reported Zoom issue. Look for variations in network metrics between the two monitoring agents. If there are significant differences in performance, it suggests that the network may indeed be contributing to the Zoom problem.

Obkio can also help you perform a Zoom assessment to identify issues and ensure that your network requirements are meeting those needed to support Zoom.

In the screenshot below, you’ll see an example of a Network Session with no performance issues. As a reference, this is what it looks like when the network isn’t the cause of your Zoom problem.

If it’s not a network issue, it might be a user issue. In this case, you can install a Monitoring Agent directly on a user’s workstation (the user who is experiencing the Zoom issues) to get a performance perspective from their point-of-view.

If you still don’t find a network problem at this point, it may just be a problem that can be solved directly on the user's workstation. Zoom, like several other hardware-intensive videoconferencing systems, uses up a lot of resources (CPU, RAM).

Luckily Obkio also monitors these important resource metrics for you!

In the screenshot below is an example of a network issue happening on both network sessions.

This implies that there is a broader issue within a common network segment that impacts all services and applications relying on the network. The affected network segment could be the local area network (LAN), the firewall, or even the local loop Internet connection. Let's explore this further:

• Common Network Segment: The fact that both network sessions display similar performance issues suggests that the problem lies within a network segment that is shared by both sessions. This segment could be a specific LAN, a particular subnet, or even a network segment behind a common firewall.
• Impact on All Services and Applications: Since the issue affects multiple network sessions, it implies that all services and applications utilizing that particular network segment may encounter connectivity problems or degraded performance. It is not isolated to Zoom alone but can extend to any other application or service that relies on the same network infrastructure.
• Possible Culprits: The problem's source could reside within the LAN infrastructure, such as network switches, routers, or cabling issues. Alternatively, it could be associated with the firewall configuration or the local loop Internet connection provided by the Internet Service Provider (ISP).

To address this broader network issue, you may need to investigate and analyze the affected network segment. We need to examine the LAN setup, ensuring the network devices are functioning correctly, and verifying the integrity of the network cabling. Additionally, reviewing the firewall configuration and checking for any misconfigurations or rules that could impact network traffic is essential. Finally, contacting your ISP to diagnose and resolve any potential issues with the local loop Internet connection may be necessary.

In the screenshot below is an example of a network issue happening on only one network session.

This means that the network problem is happening specifically towards that specific location on the Internet and that the problem is further away.

• Isolated Network Session: The fact that the network issue is occurring in only one network session indicates that the problem is not widespread across all services or applications. It is localized to the specific session or connection being observed.
• Location-Specific Problem: The issue suggests that the network problem is specific to the location on the Internet associated with the affected network session. This could indicate a potential issue with the network infrastructure or connectivity at that specific geographical location.
• Further Away Issue: The observation that the problem is further away implies that the issue lies beyond your local network or immediate network environment. It could be related to the Internet Service Provider (ISP), a problematic network node or link, or issues with routing and traffic management further down the network path.

To address this location-specific network problem, you may need to focus on factors beyond your direct control. In this case, skip right to Step 6.

If the network problem is happening on both network sessions, compare that data using Obkio’s Device Monitoring feature to further understand if the Zoom connectivity issue is happening on your end, or over the Internet, in your Service Provider’s network.

When you compare your previous data with Device Monitoring metrics, if you find CPU or Bandwidth issues, this likely means that the problem is on your end and you need to do something.

Here are a few suggestions:

• Look into what traffic is being used. Understand if the traffic is legitimate or not by looking at the firewall logs. Illegitimate traffic might be a security breach (data exfiltration), or mass data backup happening during business hours instead of during the night.
• Manage priorities in your Firewall to prioritize Zoom traffic in order to reduce the impact on Zoom during periods of congestion. This means that all the traffic towards or from Zoom will be prioritized first when passing through the network.
• Upgrade your Internet connection bandwidth with your ISP if you’re just running out of bandwidth.
• Look into your device to understand why it’s missing resources and causing high CPU usage. There may be a software problem, your device may need a firmware update, the last update may be bugged, or the device may just not have enough resources available and needs to be upgraded to a bigger device.

If you notice CPU-related metrics indicating high utilization or spikes during your Zoom sessions, it suggests that the performance bottleneck may lie within your device or computer. High CPU usage can strain system resources and affect the smooth operation of Zoom, resulting in performance issues such as lag, audio/video distortion, or freezing.

To address CPU-related issues, you can take several steps:

• Close any unnecessary applications or processes running in the background to free up system resources.
• Update your device's drivers, including graphics and audio, to ensure compatibility and optimal performance.
• If your device's hardware is outdated or insufficient, consider upgrading to a more capable system that can handle the demands of Zoom effectively.

If the comparison of your previous data and bandwidth metrics reveals low available bandwidth or excessive utilization during Zoom sessions, it suggests that your network connection may be struggling to handle the required data transfer for smooth Zoom performance. Inadequate bandwidth can result in audio/video distortion, buffering, or dropped connections.

To address bandwidth issues, there are a few steps you can take:

• Firstly, check if there are any other devices or users on your network consuming excessive bandwidth.
• Temporarily pause or limit bandwidth-intensive activities such as large file downloads or streaming on other devices during important Zoom sessions.
• Contact your Internet Service Provider (ISP) to ensure you have sufficient bandwidth for your needs and consider upgrading your plan if necessary.
