As a rural dsl customer after struggling with intermittent service over and over again for years about a year ago after many calls for service and three trips to my house to fix the wires on the service pole outside my house I finally got passable internet at 2.8 megs down and around .65 up. I pay a total bill of about $80.00 monthly (Enhanced Internet On Bill) for a phone line and internet that I used to use for faxing only many years ago, which is now used only to support Verizon DSL. I r ecently noticed that outbound emails with attachents are taking much longer to send. I rechecked my speed and although the download speed is still acceptable at 2.8 megs down, all of the sudden instead of getting uploads between .6 and .75 my upload speed has been throtled to .25.
I called and went throught the horrible recordings and nonsense gauntlet that you have to run through to talk to a script reader in India and was told that my service was within acceptable parameters. I do alot of emails with 1-4 meg attachments and this is slowing me down. It of course is not anywhere near as bad as a slow download issue. The phone rep was horrible and when I asked for an explanation, she told me that my speed was acceptable. I couldn't get any answer as to why the upload speed has dropped to one third. My internet is working fine, I'm positive the uploads have been throttled back. I of course only want what I have been finally getting for over a year. I honestly was afraid to call because I did not want my download speeds to revert to slow and none. Having had verizon phone service at my house for 22 years and internet service from Verizon for at least 10 years, I was told that if I didn't like it she could transfer my call to the termination of service number if I wanted to drop my service.
All I wanted was a straight answer, instead I got a person who read from a script, was not knowledgeable or forthcoming, and was very non-chlant about immediately asking a 22 year customer if they wanted to terminate their account. I hate this company and everything it stands for, and if and when I get a real choice other than a capped 4G Home Fusion Account from this same worthless provider I will leave in a heartbeat. Way to go Verizon, another completely dissatisfied customer. By the way, I"m not switching to Home Fusion, you can keep your 30 Gig Cap.
Does anybody have a answer as to why my upload speeds suddently dropped to one third. To me it certainly doesn't appear to be a technical issue, but a purposeful upload throttle by Verizon. I would pay more to get more, but what I had is about all that the line is capable of at my location, excepting however the upload speed of .25.
Certainly not purposeful.
And you are not making the speeds you are seeing clear.
2.8mbps and 65 what up? (certainly you don't mean 65 mbps.
Lots of things, some under your control, effect upload speed.
Remember you are talking to peers here. First we would need to know the speed you get to verizon speedtest http://speedtest.verizon.net . It is the least effected by things outside Verizon's and your control. Also try running Verizon's NDT (network Diagnostic test) and post that (minus any confidential info such as your IP address). NDT is listed on the Verizon's speedtest page but sometimes its tough to get to run.
Thanks for responding, and I know this is the community and do appreciate feedback and input. I apparently didn't put the decimal point in on the upload. I was getting between .60 and .75 up and now get about .25. The download speed is fine for dsl and I am not unsatisfied, just trying to find out why I have suddenly dropped to one third for uploads. The one of my post was in no way intended to be negative to the community, however the phone reps at Verizon support do make it difficult to maintain composure when dealing with them.
Here is the Verizon speedtest result, I will try to run the test you suggested and post the results.
Could you post your modem's Transceiver statistics or sync speeds? If you don't know how to get this, tell us what modem you have.
Verizon doesn't shape on the upstream at all, only on the downstream to prevent those who have their line cards set too high from downloading faster than they should be, and to stop buffer overruns caused by the Juniper gear. The upload can be set to anything and it'll go at anything.
I have a fairly new Modem supplied by Verizon - ActiontecGT784WN. Sync speeds are:
Downstream 3360 kps
Upstream 290 kps
Using modem for download purposes is fine. Upload works ok, but has slipped to less than half of what I was used to getting. Speed tests used to show about .6 to .75, and as I recall sync speeds used to show about 768 when checking modem statistics. I have made no changes at all to the modem or to any connections, this started spontaneously a few weeks ago.
Send buffer is really small. in that report. Not sure what typical DSL Values are, I have FIOS. What os are you running If windows XP, did you ever run Verizon's speed optimizer? http://www.verizon.net/speedoptimizer .Note shouldn't be necessary on windows 7 or later and doesn't apply to non-windows machines.

Although it shouldn't be necessary, what happens if you do let Verizon Speed Optimizer change values (the page also lets you restore back if the results are not what you want).
All my computers are fully updated Win 7's, and speed tests are the nearly identical on all of them.
