Working from home has been accelerated since COVID-19. The number of video calls for meeting with the team or clients has increased so much. But, every home has a different network environment or peripherals, and I guess you sometimes feel inconvenient to have video calls.

Here are some of the causes of audio choppiness or video freezing during video calls in remote work, as well as how to solve these issues.

Slow Internet Connection

There are four types of Internet connections. The most comfortable is 60Mbps, which is fine for playing online games and watching videos. However, once you get to 5Mbps, you would feel free to text but it’s annoying to make video calls or do anything on the Internet.

First, rest the line. In addition to reconnecting the connection on your device, try turning your modem off and then rebooting it.

Next, if the line continues to be unconnected, try switching to Ethernet rather than WiFi. Ethernet may limit where you’re available to work, but the speed would be much faster.

If you still can’t get connected, there may be a problem with the provider itself. You may want to consider a different internet provider, as your home and land may be compatible.

Devise fault

Do you ever hear a booming, annoying sound when you’re making a video call? If your device is running out of capacity, it would run slower than it should. You can check the lack of capacity from the memory status of the CPU.

Windows OS

  1. Right-click on the taskbar and select “Task Manager”
  2. Click on “Performance” tab
  3. Check the history of CPU usage and PF usage
  4. Check the available memory


  1. Open “Finder”
  2. Click “Go” on the top taskbar
  3. Click on “Utilities”
  4. Click “Activity Monitor”

If your device is running low on memory, there are two solutions: 1) close unnecessary apps to reduce memory consumption, or 2) buy more memory by purchasing external equipment. What you can do immediately is 1) So, first let’s check the resident programs and close unnecessary ones.

Camera Problems

Your camera may not be in focus if the video is blurry. Refocus the camera manually. Alternatively, the lens may be dirty. Take a silk or microfiber cloth, have it with isopropyl alcohol (do not use water), and wipe it lightly.

Recommend you buy a webcam if it wouldn’t even work. You can get a cheap one for $20.

Audio Problems

Your device and Internet connection is OK. Your headphones may be broken even if you couldn’t hear any sounds. With the current climate where meetings are more frequent, a dedicated headset would definitely help you with your video call life.

There are also some precautions to take when using a headset. If you are experiencing any anomalies, such as false-positive identification, you would see “!” on the device manager. In this case, you need to initialize the device.

Disconnect the headset from the computer and pug it back into another USB port and see the connection available even if this doesn’t fix the situation. If the message “USB device not recognized” shows, plug and unplug the headset again and it may be recognized correctly.

Use Bluetooth? Please turn off the PC’s Bluetooth connection, turn it back on, and then turn the headset back on.
