Video freezes, audio continues
Available bandwidth may be too low or variable for the current video stream.
Fix video chat problems
When a video chat freezes, lags or echoes, identify the symptom first. Reduce competition, stabilize the connection and only then ask the camera for more detail.

Freezing, delay, blur and echo have different causes
A frozen picture with clear audio points to a different problem than both people dropping at once. Describe what is failing before changing every setting.
Long conversational delay
Network latency or congestion can make both people speak over one another.
Metallic or broken sound
Packet loss, weak Wi-Fi or an overloaded connection may be affecting audio data.
Echo
Sound from speakers is returning through a microphone; headphones often solve it.
Reduce competition
Give the conversation a cleaner path
Pause large downloads, system updates, game streams, cloud photo backup and high-resolution television on the same connection. Close other browser tabs or applications using the camera. On a shared network, ask whether someone else is uploading a large file; upload congestion can damage outgoing video even when download speed looks acceptable.
Move closer to the Wi-Fi router and remove obvious obstructions. A wired Ethernet connection is usually more stable when available. Switching networks during a live conversation may interrupt it, so finish or reconnect cleanly after the change.
- Pause uploads as well as downloads
- Close unused camera and conferencing applications
- Move closer to the router or access point
- Use Ethernet when the device supports it
- Avoid changing several variables at the same time
Protect the conversation
Prioritize voice and use patient turn-taking
If the product or device provides a lower video-quality option, use it. Keep your face well lit so the encoder can produce a useful image with less noise. Use headphones and position the microphone consistently rather than speaking from across the room.
With noticeable delay, pause after a sentence and let the other person take the turn. When both people interrupt, agree on a simple reset: one continues, the other responds afterward. This is a connection problem, not a personality judgment.
Read a connection test carefully
A single speed number does not describe call quality
Download and upload throughput matter, but latency, jitter and packet loss can disrupt a conversation even when a speed test reports a large number. Latency is the travel time for data; high latency creates conversational delay. Jitter describes changing delay; packet loss means some data never arrives. Video can blur or freeze while the product tries to preserve usable audio.
Run a test only when you are authorized to use the network, and compare it with the actual symptom rather than chasing a universal minimum. A result taken beside the router may not describe the room where you call. Likewise, a quiet morning test may not represent an evening when several people share the connection.
Do not install an unknown “network booster” sent by another participant. Use the operating system, router provider or a reputable test you choose independently. Support usually needs the symptom, time, network type and device more than a screenshot containing your public IP address.
Mobile networks
Signal strength, movement and data cost can change during the call
On cellular data, stay in one place with a stable signal rather than walking between coverage areas. Switching from Wi-Fi to cellular can interrupt the current connection. Video also uses more data than text or audio, so review your mobile plan and device data controls before a long session.
Battery-saving and low-data modes may reduce background activity or media performance. That can be useful, but it can also change camera behavior. If a problem appears only in one mode, note it before changing the setting. Keep the device powered and avoid heat buildup during a long call.
Public Wi-Fi may be congested and is a poor place to discuss private information. Prefer a network you trust, keep the device updated and do not accept certificate warnings or install profiles merely to make a chat work.
Reconnect or escalate
A fresh connection can clear a growing delay
When lag increases over time, leave the conversation and reload the page. Restart the browser if camera or audio behavior remains abnormal. If every web service is slow, restart the local router only when you are authorized to do so and can tolerate the interruption.
If Nanacam alone repeatedly fails, contact [email protected] with the device, operating system, browser, approximate time and symptom. Do not send passwords or private conversation material.

Helpful answers
Both matter. Your outgoing camera and microphone need upload capacity, while the other person’s stream needs download capacity. Stability, latency and packet loss also matter.
Your pace, your conversation
Try video chat when ready →Stabilize first, sharpen second
Reduce competing traffic, protect clear audio and reconnect when delay begins to control the conversation.
