| [speed/latency] Verizon 3/768 speed drop
Last December I was upgraded to the 3/768 speed from the 1.5/386 I had before. Everything was working great with speed test of 2500 to 2900 down and download tests of 340 to 360. Then a couple week ago I did a Verizon speed test and it showed down as low as 700. I did it again it would stay the same or it would jump up to 1200 or so. After several tries it might jump up to 2100 to 2600. I have two computers and they are both doing the same thing. I tried other speed tests and am seeing the same thing. I have tweaked my setting and run the tweak test and it tells me everything looks good.
I called Verizon and the tech told me that it must be my pc because my modem is showing 3360/864 on the down stream and up stream. He claims that is what is coming into my modem and the problem has to be in my pc. He said it is probably a virus, spyware, adware, or I need to clean my pc up.
Is he correct? I believe he is wrong and I told him I would be calling back after I cleaned up my pc. I did so and it still does the same thing on my speeds. Please help, this is driving me nuts!
Thank You |

| Call up Verizon tech support. I am having the same problems as you, since Friday January 27th. My pc's are clean. I connected 3 desktops and one laptop all with the same problem.
This is both with and without my router. I posted something this morning in the Verizon direct forums. My next step is to talk to a rep via the live chat interface which I plan to do to later today.
Good luck to you.

First, I don't recommend using the Verizon speed test. I've found it to be inaccurate. Try using SpeakEasy.net instead »speakeasy.net/speedtest/, and try NY and DC, and then LA and SF, and post back here, along with your OS and modem stats. Are the slow speeds all of the time, or only at certain times? If only certain times, it sounds like net (or Verizon) congestion. If you have a router between your pc's and the modem, try running directly to the modem. If it's possible, plug the modem into the NID outside of your house and see it it helps. These are all pretty much just the generic dslreports things to do/check first (kind of like what Verizon support does, only better), so don't worry if none of them fix them.
I recently went through almost the same thing for 2 months with Verizon, getting the same thing from them about it being my pc (all 3 of them, and all 3 suddenly, yeah right). It wasn't until a tech came out and said that the line stats he was reading into the house were actually great, and I replaced my modem, that I dug deeper into my systems. Even though I made no changes at all to any of them, I found my "tweaks" were now killing my speed, on all 3 machines. Using some really off the wall numbers, I've been able to get my speeds back, but every tweak test out there tells me my system is not configured properly. Tell that to my speeds. Several people who gave lots of time helping me could do nothing but shake their heads because they've never heard of anyone with a problem quite like mine. Even though I found a solution on my end, I suspect the cause was on Verizon's. I only say this because of 3 things. First, the suddeness with which it started on 3 separate machines. Second, I know they've been swapping out a lot of hardware at my CO (told to me by someone in the CO). And third, because it all started the same day I was no longer able to log in with multiple ip addresses. None of this is proof, but right now nothing else makes any sense. |

| Thanks for the response jodokas96.
Here are the speed tests. NY 1683/717 DC 1935/717
SF 2569/712 LA 2561/713
What I notice is on a download. Before it would start out higher and then settle out between 342 and 360. Now it starts out low around 180 or so and works up to around 310. It just is not normal!
I was on line with tech support for an hour this evening and was told that what I was getting, 1761 to 2954 was acceptable to them. I ask who I could go to above them after hearing that! I was not a happy camper! Of course after ending with them, I checked the speed again and it was down below 700 again. I used the Verizon test site.
I told the person that nothing changed on my end but the speed just started jumping all around a week or so ago.
I am trying replacing my phone cord and trying different phone jacks. I do not know if I can make it to the NID but will try.
Thanks again for the reply! |

My guess is that they are getting really congested up in the NE. Im in massachusetts, and am having the same exact problem. Friends of mine in NY are having the same problem as well.
One thing I find really odd is that there is apparently no congestion when I try the speakeasy SF or LA, but tons of congestion in NY and DC. Upload is fine both ways but download is having severe problems in the east coast speed tests. I think they have an overloaded or not properly functioning router in NY somewhere imo. Its really wierd that I have no problems on the west coast speed tests, but terrible results with east coast. |

| Ok, I think you 2 have been the people I've been looking for, namely someone else that has my problem. Those good speeds all the way out west are pretty close to confirming it. Dslammer, I already told you what to try in the other thread, and I'm really starting to suspect that it will help. kbd13, if you know what RWIN is, try setting it to 17424, and see if that helps to the east coast sites. If you don't know what it is, try what I just told dslammer to do here: »[speed/latency] Speed Issues |

So jodo, do you think the problem is some sort of congestion up in the NE with oversubscribing? |

| If you change those settings to what I suggested and the speeds to the east coast tests jump (the west coast should then fall off), then no, I don't think it is congestion in NE. I suspect hardware changes on Verizons side, but that is just a hunch. |

| It's really not necesarry to try it. It's like DRTCP, but with more reg values to mess with. It has some presets, but with your problems they wont work. With DRTCP, if you want to try some different RWIN values that don't stray a whole lot from what we came up with, go for it. Try to keep them multiples of 1452. Also, as a final test, try this: »»ftp://ftp1.optonline.net/pub/test64.exe. Stop it at the 30% mark and note your speed. Then cancel the download. Do the same for this link: »»ftp://ftp.aol.com/aol6.0/171340/setupaol60.exe. You should be able to get about 345-355 kB/sec. for both of them. |

| I can't thank you enough for your help and others on this forum.
I am sorry I had to get off line last night when you were so kind to help me but it was getting late and work comes early.
I will try the links you sent, use this one a lot "ftp1.optonline.net/pub/test64.exe", when I get home from work.
If Verizon is having a problem, why do they not fix it? We should not have to go through all of this. It really ticked me off when they told me that the speeds I am getting is acceptable to them. If that was the speed / performance I was getting before I could accept that but it is not. They need to fix the problem!!!!
Thanks again! |

3 edits | I don't know what the problem is. It took me since Thanksgiving to get to what we did in a few minutes last night. That's because no one once suggested lowering RWIN, because up till now, that made no sense. I stumbled on it by pure accident. I don't really think it's a problem so much on Verizon's end, if you really think about it. Let me explain. I do believe it has something to do with hardware upgrades on the Verizon network. However, everyone that has had the problem so far has tweaked their RWIN up to a much higher value (63888 or so) than Windows default (17520). The values that me, you, Dslammer, and now I beleive Trooper (hasn't got back with results yet) have now tried are much closer to the Windows default. Most user's out there have never tried tweaking their speeds, so won't notice it. Also, a lot don't check to see if their speeds are where they should be. At my worst, I was still getting about 800-1000 kbps, so browsing wasn't really affected, which is where the average user would notice something funny. What we see as a problem, Verizon might just see as a solution for those that say they need to tweak. Remember, this is all just a guess, I don't actually know anything. I have no real background with any of this stuff either. I only came to dslreports for the occasional speed test, and to this forum to check for new speed upgrade packages. I wasn't a member until 2 months ago when I knew I had a real problem that would require real help. I've learned a lot here (you guys in this forum know who you are; IrishShark in the Broadband Tweaks forum) , as well as over at testmy.net (guy named trogers over there spent lots of time explaining things and trying to help out).
I don't see what we've done here as a fix just yet, merely a band-aid. The fact that I can tweak my system to get a good result for any speed test (just tell me how far away it is) disturbs me. If I only visited sites in my general area that might be ok, but this isn't the case. But if this is the start of something new for Verizon, it just may put the tweakers out of business. God I hope not! If I see others having this issue, I may consider giving that Verizon Direct a shot and asking them about it. Anyone know how they respond to just general information seeking as opposed to actual problem solving? |

I'm having the same problem as everyone on this thread - experiencing SEVERE speed issues, with NO resolution from Verizon. Consistently getting speeds of 500 Kbps down (uploads appear unaffected) on a 3.0Mpbs service. Have tried 2 different modems (Westell Wirespeed and 6100), 3 different routers (Motorola, Linksys, and now Netgear), and 3 different computers (running XP *and* Mac OSX!). Verizon keeps telling me my connection is "perfect" and that it's a problem between the modem and my computer(s). I have no idea what this could be (have tried swapping out cables) and they can't tell me.
Is changing the RWIN settings possible in a Macintosh, and might it help? If so, how does one do it?
Thanks in advance! |

I left Verison dsl because I had the same problem during peak-hours. One thing they won't admit is they over-sold subscriptions and it's causing the slow-downs. They will make you your PC vendor, Microsoft, and who ever just to make you tired of wasting your time on the phone. I spent 4 months w/ those ppl, finally gave up and moved on to covad. GL. |
