- What is Bufferbloat
- Bufferbloat causes latency spikes during file uploads and downloads on network
- It occurs when network packets are temporarily buffered before sending
- Affects real-time applications like VoIP, gaming, and video calls
- Testing Methodology
- Test latency while running download and upload speed tests
- Compare results with unloaded connection latency
- Use HTTP requests instead of WebSockets for testing
- Test over ethernet cable to isolate modem-router bufferbloat
- Best Routers for Fixing

- NETGEAR Nighthawk Pro Gaming offers DumaOS with SQM
- IQrouter IQRV3 designed specifically for bufferbloat reduction
- Ubiquiti EdgeRouter 4 supports up to 350 Mbps with SQM
- Solutions and Recommendations
- Disable bandwidth-heavy tasks on network
- Ensure router connection speed matches internet speed
- Upgrade router with SQM implementation
- Use Cloudflare CDN for speed testing
- Check browser compatibility for accurate results
