Summary
"You're breaking up," or "You sound like a robot" are the most common phrases heard in remote work. When your video freezes or your audio drops out during a Zoom or Teams meeting, 99% of the time it is an issue with your home Wi-Fi network, not the software itself. This guide helps you diagnose and fix poor connection quality.
Symptoms
- Coworkers say your audio is cutting out or sounds robotic
- Your video feed is blurry, blocky, or completely frozen
- Zoom/Teams displays a warning saying "Your network bandwidth is low"
- You get disconnected from meetings entirely
Prerequisites
- You must be on your home Wi-Fi network
Instructions
1. The Quick Fix (During a Meeting)
If you are currently in a meeting and everything starts breaking up, do this immediately to save the call:
- Turn off your video camera. Transmitting HD video takes massive amounts of bandwidth. Turning it off leaves all the bandwidth for your microphone.
- Close all other apps. If you have 50 Chrome tabs open, or you are downloading a large file in the background, close them immediately.
- Turn off Virtual Backgrounds. Blurring your background or using an image takes significant processing power. If your laptop is overheating, it will struggle to process the video.
2. Check Your Network Speed
If you consistently have bad quality, you need to prove whether your internet provider (like Comcast or AT&T) is giving you the speed you pay for.
- Open your web browser and go to
fast.comorspeedtest.net. - Let the test run.
- You are looking at two numbers:
- Download Speed: (How fast you receive data). You need at least 15 Mbps for smooth video calls.
- Upload Speed: (How fast you send data). This is the most critical number for video calls. You need at least 5 Mbps. If this number is below 2 Mbps, you will always look and sound terrible to others.
3. The Physical Environment (Wi-Fi vs. Ethernet)
Wi-Fi signals hate physical obstacles. Walls, microwaves, and distance all destroy your internet speed.
- Move closer to the router: If your home office is on the second floor and your Wi-Fi router is in the basement, your signal is likely very weak. Move to the same room as the router for an important call.
- Use an Ethernet cable: The ultimate, permanent fix for bad home internet is to plug an Ethernet cable directly from your laptop (or docking station) into the back of your Wi-Fi router. A hardwired connection is immune to Wi-Fi interference.
4. Who Else is Using the Internet?
Your home internet acts like a single pipe of water. If someone else turns on a hose, your water pressure drops.
- If you are on a very important client call, ask your family members to pause downloading massive video games (Xbox/PlayStation updates are notorious for killing home internet) or streaming 4K Netflix movies.
Troubleshooting
| Symptom / Error | Potential Cause | Solution |
|---|---|---|
| Speed test is fast, but Zoom is still terrible | VPN Interference | If your company requires a VPN, disconnect from the VPN (if allowed) while on the video call to improve speed |
| Only my audio is bad, video is fine | Bad microphone | Your internet might be fine, but you are using a cheap built-in laptop mic. Use a dedicated USB headset |
| Router requires restarting every day | Failing hardware | If your Wi-Fi router is more than 5 years old, it may be failing. Contact your internet provider for a replacement |
