Extremely slow DSL speeds. Up speed higher than Down speed. Please help.

Enthusiast - Level 2

I just purchased the 1.1 - 3.0Mbps hi-speed DSL package.

Verizon speed test shows .17Mbps down and .536Mbps up. This is obviously curious for two reasons: 1) the incredibly slow down speed, and 2) the down speed being slower than the up speed. 

Curiously, speedtest.net shows different results:

2.45Mbps down, .55Mbps up

What could this mean? Transceiver data follows.

Transceiver Revision 3.3.6.10.0.1

Vendor ID Code 4D54

Line Mode ADSL_G.dmt

Data Path FAST  


DSL Speed (Kbits/Sec)

Down Stream Path 3360

Up Stream Path 864

Margin (dB)

Down Stream Path 27.1

Up Stream Path 16.0


Line Attenuation (dB)

Down Stream Path 20.1

Up Stream Path 8.0


Transmit Power (dBm)

Down Stream Path 6.8

Up Stream Path 11.9

Thanks in advance for any advice/ assistance you can offer. This is extremely frustrating.

OK. It seems as though you're suffering from what some people call "Juniperitus." If you're on a Remote DSLAM that uses Alcatel Litespan equipment (Litespan 2000 for example) along with being connected to a Juniper Networks ERX edge router, there tends to be an incompatibility between the two pieces of equipment that causes TCP connections and pretty much any other form of transfer to see artificial packet loss, which results in transmission. This results in inefficiency in every transfer, so what you're seeing is simply a result of all of this. In the past when Verizon first installed Litespan, they were using older Redback Networks edge routers, which did not create such problems. I'm on a Litespan and happen to still be on a Redback in my area (one of remaining ones still in operation in my area) and I get my max line speed with no issue. It's unfortunate that these actually perform better despite the Junipers being far better edge routers in terms of capacity.

I know someone who should be able to get this fixed for you. I'll send you a Private Message.

You have a nice running Telephone there, so the physical circuit should not be causing the problem you're having. Are the results you receive consistent with each test, or does the speed vary based on which server you pick? Visit http://www.giganews.com/line_info.html and post up the Traceroute the page shows, if you wish. Be aware that the final hop (bottom-most line of the trace) will contain a hop with your IP address in it. Remove that line. What I'm looking for is a line that mentions "ERX" in it's name towards the end. If for some reason the trace does not complete (two lines full of Stars), keep the trace route intact.

Thanks for the prompt reply!

If I understand correctly, when I run the Verizon speed test, the results always fall within .1 - .25MBps down speed. I've run it nearly a dozen times. I tried selecting other States near mine from the drop-down list, and the results are consistent, or worse.

The traceroute did not complete (thus not exposing my IP). I will post in its entirety below:

OK, that's what I was looking for. It looks like you are on a Juniper ERX router. Now we need to see if there's a chance you are on certain equipment on Verizon's end that would not be playing nice with the data.

Download the following file using either your web browser or an FTP Client. Let it run for a few minutes, and you could consider restarting the transfer after a minute to see if it will go any faster.

ftp://fedora.mirrors.tds.net/pub/fedora/releases/15/Fedora/x86_64/iso/Fedora-15-x86_64-DVD.iso

On the 3Mbps package you should max out around 340-360KB/s. If the results work out as they should with the above download, you should start to see your speed get close to 300KB/s.

Thanks again for your continuing assistance.

I closed all applications except this browser, then started the download; canceled then restarted the download after a minute; paused then resumed the download after a minute; let it then run for 3 minutes uninterrupted.

Download peaked at 172 kB/s, and averaged about 165 kB/s.

At this point the donwload has between 5 and 6 hours remaining.

Max number of unresponsive hops reached (firewall or filter?)

Had good service for over 5 years

Noticed slow down a few months back inconsistent connects, slow page loads (Netflix unable to stream which had been very reliable for over a year), I had attributed it to major line work 2 blocks over and assumed it would improve. Just rechecked my phone number and program said no high speed available at this number.

I am more than a little upset that the system knew I couldn't receive high speed and yet they continued to bill me for it.

The Fedora download is 7 to 9.6 KB/s only 4 days 18 hours remaining.

Any help would be greatly appreciated.

Your issue may or may not be from the Juniper you're connected to, but I guess we'll find out soon enough! Are the speeds you're seeing now consistently shoddy/slow throughout the day, or are they where they should be in the morning and early afternoon hours? What speed package are you supposed to be provisioned for?
