Thanks for this info! I actually use my own modem, the Arris S33, and did find out it does not have the puma chipset.

I’ll try to find out what you mean here, tomorrow! Working now. Thank you! Will report back tomorrow.

Oh?? Hmm. Good to know.. it has automatic bypass on the QoS… interesting. Well, when I disable ipv6, I get half the download speed even at 100% download slider. That’s what ruins it, for me?

I tried that. Mentioned what happens in my intro message, up above. It’s really weird.

Yes, I have. My thoughts exactly. That’s why I hard reset the router between one of those, too. I was like.. this doesn’t seem to be changing the speeds or outcomes.

This is why I don't know that I'm doing it right.. I tried to follow direction. However, when I move the sliders - I assume you guys mean the sliders in the QoS for download/upload? They're really not doing anything to my connection. Even with router restarts in between. Picture proofs attached. The 58ms/46ms pic is with sliders at 85-85. The 50ms/53ms pic is with sliders at 50-35. The 52ms/46ms pic is with sliders at 35-20. I assume I'm doing something wrong? And yes, I tried ping plotter. ignore the giant jumps, as they were from when I did the bufferbloat website tests to test the sliders.

One day I can sit down and really try and understand what that guide is saying to do.. I may just not be technical enough, though, haha. Thanks for replying!

Fiber isn't available to me, unfortunately. I tried looking

So, are you guys saying it's pretty impossible for me with my connection to be able to better my bufferbloat, then? Because I'm held down by the old copper wires of cable?

Thanks for the replies. Well, it seems Comcast nailed down my issue, at least for today.. I talked with a rep on messaging for hours, this morning, and then I've done a 5 hour test stream since then, and had 0 dropped frames. So.. Here's to hoping that's fixed. .....at least it has been, for today, haha. Althoughhhhh.. I played a game of Valorant, just now, and it popped up with a couple 'network issue' icons, here and there.. which is what it was doing before, when I was getting lag spikes/going red latency on OBS during streams. So.. That also leads me to maybe think it's NOT fixed...... However, OBS did not go red this time, during said lag spike.. So. I don't know.. Your guess is as good as mine... Now, as far as bufferbloat goes.. Just took a test while doing the test stream. Goes without saying, apparently it didn't like to test while I was doing the test stream.. But let's be honest.. 99% of the time if I'm playing games, I'm going to be streaming.. Being a streamer, it goes without saying.. So, my question is now.. Where should I start? Anyone have any info for me as to why my connection download cuts in half when I take off ipv6 in router settings to disabled? But upload stays the same? That seemed to be the only way I achieved A ratings on the bufferbloat website.. But only because I had a miniscule 150mb download speed.. Any other things I should try? Thank you, RouterUser

Hello! Thanks for the reply! Yeah, I saw you post that link in many other posts, and did try it out. Not gonna lie, that program and how to work it confuses me. Haha. I'm slow 😅 But yeah. Working on the internet issues. Was hoping someone might have an idea on that, as well.. Since those just started out of the blue a few weeks back, and Comcast/Xfinity doesn't really want to accept responsibility. But once those are fixed, I do want to understand how to fix this bufferbloat I have.. As far as I know, even before these issues with my connection, I was garnering the same results.

Hello all, So, I've googled.. I've searched these forums.. I've tried about every single thing anyone has suggested.. I come across a few problems with anything I try. First of all, I sit flush around these speeds, when I have DumaOS QoS set to my 'Xfinity' speeds from a speed test (900mbps/38mbps) and a 70/70 setting on the QoS sliders (see attached picture). I messed with sliders like crazy, but no matter what I did with them, the only one that 'kind of' noticeably changed speed when I messed with it, was the upload one, and it never really came down in congestion latency (unless ipv6 was turned off, but that ruined the download speeds, as I'll explain momentarily). So, the sliders/QoS really didn't work much, for me.. So then I tried looking around on google and these forums.. Trying what people suggested.. I tried to turn OFF ipv6 in the router settings.. However, that made me get half the internet speed I was getting with it turned on (download). Upload stayed the same. However, even at half the download speeds on a speed test, the bufferbloat website kept either clocking me at 350mbps download, and giving +10 download latency, or clocking me at 160mbps download, and giving me +0 latency.. Although neither time I changed any sliders or speed information in DumaOS. So I'm unsure why it was so back and forth and inconsistent.. Upload with ipv6 turned off was getting roughly the same speeds, however clocking at 32mbps with a +10 latency.. So, I'm not sure what was going on. Sure, the rank changed to an A or B, but my download speeds also went down to either 320 or 160mbps.. when I pay for 'gig internet.' So I figure the loss wasn't worth it. So, I turned ipv6 back on. I've tried just about everything I can think of, and, at this point, am very confused at what to do. Just FYI, when plugged into the PC straight, no router, I get about the same speeds and bufferbloat ratings. Not sure if that info helps or not. Also, on XR450 V2.3.2.134 firmware ('newest'). I'm unsure what to do or what to try, at this point. Any ideas would be great. Also, if I'm just held down by the router, I'm open to moving on/forward with a newer model or something.. But I swear, this one isn't that old, so.. I don't know. Thank you, RouterUser EDIT: On a side note.. For the last 2-3 weeks, Comcast has been hitting me with some lag spikes.. They happen every 2-20 minutes, and last about 3-10 seconds, each time. Usually around 5 seconds. OBS Studio goes from green upload speed to red, usually. Sometimes even dropping to 0kbps upload, briefly.. Before going green again, seconds later. I've contacted Xfinity multiple times, each time with them saying things look great on their end.. One time them saying my modem was sending back 'errors'.. I replaced my modem with an older modem, same issue. I replaced my modem with a brand new modem, same issues.. I bypassed the router completely to just the modem.. Same issues.. They sent a tech out who checked my hard wires, replaced my Cat5 cable going between the router and modem, and did a speed test on everything while he was here with his little tablet thing, and he said everything seemed fine, and he was unsure where the issue lied. So, I'm stuck, still getting this new issue, and unsure how to fix it. Also, each and everytime I contact Xfinity, I either get a call or a text, telling me 'health diagnostics were ran, and they believe my issue has been fixed, and to try to replicate the issue.' And each time, nothing was changed as far as my issue goes. (4 times in a row they've done that, now.... Little sus.). So, any ideas on that front would be great, too. I'm paying for 1200mb speeds from them, and I get roughly 800-900, anyways.
