Hey All, So I ran this speed test on my cable connection. I have great results, with the exception of my F in bufferbloat. How do I resolve this bufferbloat issue. The information on DSLReports says to adjust my QoS settings to limit my download and upload to around my connection speeds. The c6300 does not give me control over the QoS settings. Any ideas? Thanks, Chewiegoodie

Hello Chewiegoodie Have you tested at another site for bufferbloat? and are you experiencing any issues because of it? hope to hear your feedback DarrenM

Bufferbloat is undesired latency/lag when a router is handling a lot of traffic. It always occurs at the bottleneck link (your cable/DSL connection). It is caused by the router forces time sensitive traffic (gaming, Skype, Facetime, VoIP, DNS lookups, etc.) to wait behind large flows of data (downloads, Youtube uploads, etc). You have probably experienced this as laggy, sticky performance when someone else is using the network. This is a solved problem using the fq_codel algorithm (or others). These have been part of the Linux kernel for over three years. I'm using it with OpenWrt firmware on a Netgear WNDR3800 quite successfully.DarrenM: Can you speak to when Netgear might incorporate fq_codel or some other algorithm to combat bufferbloat?

I work from home and do VOIP and screensharing sessions over GoToMeeting frequently. I have been experience major slowdown issues during these sessions. The most recent time this happened no one else is in the house or using the network. I am trying to rule out everything that could be causing it and this buffer bloat issue is on the list.

That would be really frustrating. I'm not sure, though, what you mean by major slowdowns: what do you see? (slow downloads, lag in responses, ?)

It seems to slow my entire system down to a crawl. Which doesn't seem to point towards a network issue, but my performance counters are not spiking. My CPU utlization is usually around 60% and memory is around the same and I have an SSD which is barely being used at the time. This is only an issue when I am doing a screen share session. I have had similar issues with sharing over Lync, which is now Skype for Business. PC Stats:Intel i7-5600U CPU 2.6GHZ16GB Ram500GB SSD As soon as I stop sharing my screen everything goes back to normal. So I am wondering if this is a bad response by my sharing applications to the buffer bloat issue. DarrenM What other buffer bloat evaluation tools would you recommend? I have run it from multiple browsers and with "Private" as well as without. I always receive an F on bufferbloat.
