# How to Check Whether the Network Is Smooth

> Run a network diagnostic in DingTalk to test bandwidth, latency, packet loss, and firewall connectivity before joining a critical meeting.

Video meetings support network detection, which helps quickly determine whether audio stutter or blurry video is caused by network issues.

## View the Current Network Status During a Meeting

**Entry 1:** Move the mouse over the signal icon in the upper-left corner. A pop-up automatically displays the current network status, uplink and downlink bandwidth, packet loss rate, and latency. Click **Details** to view more detection data.

**Entry 2:** You can also go to **More** > **Settings** > **Quality Monitoring** at the bottom. On mobile, tap the triangle icon at the top of the video meeting and view **Network Detection**. Together with weak-network prompts, this helps you understand the current network status and troubleshoot lag or latency.

## Detect Network Status Before a Meeting

Use the video meeting network detection tool. Select the network node closest to you, click **Start**, and wait for the detection to complete to view the network report.

## Recommended Network Conditions

| Client                            | Maximum Video Resolution | Maximum Frame Rate | Recommended Bandwidth |
| --------------------------------- | ------------------------ | ------------------ | --------------------- |
| Mobile video                      | 720p                     | 15 fps             | 1.5 Mbps              |
| Mobile sharing                    | 1080p                    | 5 fps              | 1.5 Mbps              |
| Desktop video                     | 1080p                    | 15 fps             | 2 Mbps                |
| Desktop sharing                   | 1080p                    | 5 fps              | 1.5 Mbps              |
| Hardware meeting terminal         | 1080p                    | 15 fps             | 2 Mbps                |
| Hardware meeting terminal sharing | 1080p                    | 5 fps              | 1.5 Mbps              |

To ensure meeting quality, internet packet loss should be below 5%, and latency should be below 100 ms.
