What is bufferbloat caused by?
Bufferbloat is a cause of high latency and jitter in packet-switched networks caused by excess buffering of packets. In such equipment, bufferbloat occurs when a network link becomes congested, causing packets to become queued for long periods in these oversized buffers.
How do I fix bufferbloat on my router?
In general, the most effective way to combat bufferbloat is to implement so-called Smart Queue Management (SQM) in your router. Ideally, your router should be running the most effective SQM algorithms that specifically address bufferbloat, such as FQ-CoDel or the more advanced CAKE (Common Applications Kept Advanced).
Can ISP cause bufferbloat?
Yes, if your router is underpowered and you have a high-speed connection through the ISP, then your router could become a bottleneck and show bufferbloat.
How do you identify bufferbloat?
A Quick Test for Bufferbloat
- Start a ping to google.com. You’ll see a series of lines, one per ping, typically with times in the 20-100 msec range.
- Watch the ping times while the speed test is running. If the times jump up when uploading or downloading, then your router is probably bloated.
What does anti bufferbloat do?
Anti-bufferbloat is a feature of the Duma operating system. Anti-bufferbloat prevents a single device from using all of your network’s bandwidth. By using the anti-bufferbloat feature you can prioritize and control which devices or games you want to have more bandwidth.
Why is my upload bufferbloat so high?
Bufferbloat will only happen if your connection is overloaded. The ISP will place data into buffers if there is no room in the transmission to your house rather than discard them.

How do you know when your modem is going bad?
5 Warning Signs Your Cable Modem is Dying
- Connection indicator lights have turned off even if you can still surf the web.
- Data transfers/downloads are slow.
- The connection speeds are slow.
- The modem is making a lot of loud or weird noises.
- The modem turns off or stops functioning.
Do I have bufferbloat?
Measure the Bufferbloat: Use the DSLReports Speed Test or Waveform Bufferbloat Test to measure the latency under load (this is a good measure of responsiveness). If the test shows a letter grade worse than a B, you probably have bufferbloat.
