R6700v2 Buffer bloat How can we fix this ? Can we get SQM or QOS that works like it ?
I get a lot of buffering problems sometimes with this router as it builds up buffering bloat . I tested it on www.waveform.com and got this result --- > https://www.waveform.com/tools/bufferbloat?te...
What speeds do you pay for?
What modem/gateway do you have it connected to?
have you tested your buffer bload directly connected to the modem/gateway?
I pay for 100mb down and 10mb up and i get more than that but the buffering gets really bad . The modem is what Spectrum gave me and is a Hitron e31t2v1 Docsis 3.1 . I tried connecting my line directly to the modem but i get no connection and windows 10 wouldn't fix it . I think spectrum made it so i have to go through my router or i just have to restart that modem and have my line connected to it instead of the netgear router.

I turned QOS off in the router and now getting a little better connection but also i added in cloudfare's free dns in settings of the router 1.1.1.1 and that helped the ms ping buffering some but still over 100ms ping down added together with local and streaming buffer .
Netgear Firmware just isn't good enough to get rid of buffering problems at least not in this model. It doesn't have enough options . I can change upload to buffer a little in settings of QOS but there are no settings for download buffering to tweak for this router .
disconnect everything from the modem and reboot it.
Then connect a pc.
Try it that way
I connected the computer directly to the modem and the buffering was the same . The Router is supposed to fix the buffering problem IF QOS worked correctly. QOS on this model only has the option to throttle Upload which i was locking at 10mb up and the speed tests at 12 to 14mb up .There is no option at all for download buffering which is where most of the problem is anyway. I get around 50 to 80 ms extra ping with the download and even more with longer distances . Lots of people changing over to ddwrt ,tomato and openwrt on routers IF they can upgrade the Firmware easily .With the chipset on this it can not be easily changed to Openwrt which they have a replacement for this router's Firmware . If you look at this page you can see that SQM for OpenWrt has more options than the pretty much half thought out QOS that my Netgear router has . [OpenWrt Wiki] SQM (Smart Queue Management)
If Netgear could just add in that option for throttling download speed as well like they have on other models,I think the buffering could be managed . Here's my latest test which shows the download has the worst buffering which went up to over 200ms .
