Your video calls freeze and drop whenever someone streams Netflix in 4K - here's how to prioritize bandwidth so everyone's happy.

💡What's Happening

You're on an important Zoom call and suddenly you freeze, your audio cuts out, and you're watching the dreaded "reconnecting" spinner. Meanwhile, someone downstairs is streaming 4K Netflix or Disney+ on multiple TVs. A single 4K stream uses 25 Mbps, and multiple streams can easily saturate your entire internet connection, leaving nothing for your video call. This is one of the most frustrating work-from-home problems, but it's totally fixable with the right router settings.

✓Quick Checks (Do These First)

  • Run a speed test. Go to fast.com and see what bandwidth you're actually getting. If you're on a 100 Mbps plan and have three 4K streams (75 Mbps), there's nothing left.
  • Ask if anyone is streaming right now. Confirm that streaming is actually the problem.
  • Check your video quality settings. Zoom and Teams don't need much - you can lower video quality in the app settings to use less bandwidth.
  • Close other apps. OneDrive, Dropbox, and cloud backup services can eat bandwidth during calls.

🔧Step-by-Step Fixes

Fix 1: Set Up Quality of Service (QoS) to Prioritize Video Calls

This is the most effective solution - your router can prioritize video calls over streaming.

  1. Log into your router admin page (usually 192.168.1.1 or 192.168.0.1)
  2. Find QoS, Traffic Prioritization, or Quality of Service
  3. Enable QoS
  4. Set priorities:
    • Highest: Video conferencing apps (Zoom, Teams, Meet) or your work computer
    • Medium: General web browsing
    • Low: Streaming video (Netflix, YouTube, etc.)
  5. Some routers let you prioritize by device - put your work computer at the top
  6. Save and reboot your router

Fix 2: Limit Streaming Quality on Smart TVs

You don't need 4K for casual watching - HD looks great and uses way less bandwidth.

  1. On Netflix:
    • Go to Account (on the website) → Profile & Parental Controls → select a profile
    • Click Playback settings
    • Change from "Auto" to Medium or Low (saves up to 5x bandwidth)
  2. On Disney+, Hulu, Amazon Prime:
    • Look in app settings for "Video Quality" or "Streaming Quality"
    • Change to "Data Saver" or "Good" instead of "Best" or "4K"
  3. This drops usage from 25 Mbps per stream to 5-8 Mbps - still looks good but leaves bandwidth for calls

Fix 3: Create a Work Schedule and Communicate

  1. Set clear times when you have important calls
  2. Ask family members to avoid streaming during those windows
  3. Post the schedule on the fridge or in a family chat
  4. Most people are happy to accommodate if they know ahead of time

Fix 4: Set Bandwidth Limits on Streaming Devices

Some routers let you cap bandwidth per device.

  1. In router settings, find Bandwidth Control, Rate Limiting, or Device Management
  2. Find your smart TVs in the device list
  3. Set maximum download speed to 10-15 Mbps per TV
  4. This prevents any single device from hogging everything
  5. Streaming will auto-adjust to a lower quality, but calls stay smooth

Fix 5: Upgrade Your Internet Plan

If you've got multiple people working from home plus multiple streaming devices, you might just need more bandwidth.

  1. Calculate your household needs:
    • Each video call: 3-5 Mbps
    • Each 4K stream: 25 Mbps
    • Each HD stream: 5 Mbps
    • General browsing: 10-20 Mbps
  2. If your total exceeds your current plan, call your ISP and upgrade
  3. Going from 100 Mbps to 300 Mbps often costs only $10-20 more per month

⚠️If Nothing Worked

If you've tried QoS, limited streaming quality, and you're still having problems, check if anyone is uploading large files during your calls - cloud backups, Dropbox syncing, or even someone else on a video call. Upload bandwidth is often much more limited than download (like 10 Mbps up vs 100 Mbps down), and video calls need upload to send your camera feed. Pause backup services during calls and check for upload bandwidth caps in your router's QoS settings.

📞When to Call a Pro

If router settings intimidate you or you've tried everything without success, a tech can diagnose exactly where the bottleneck is - whether it's your router, your internet plan, or network configuration. They can also set up advanced QoS rules that automatically prioritize work traffic without any manual intervention.
