Slow DSL in evenings

Enthusiast - Level 2

Hello,

I'm getting some extremely slow download speeds with my Verizon DSL during afternoons and evenings.  I'm supposed to get 768 kbps, but typically I'm getting in the neighborhood of 50--100 kbps during those times. Between 7 and 10 PM, quite frequently I can't even get the dsl test sites I use to load---it will sit and chug for minutes at a time.  In fact, I often can't do much of anything on the internet during that interval.

It works fine in the mornings however.  I get right around 768 kbps download speeds then.

So I called tech support, and they claim my line is fine.  They even ran a 24-hour test on it, and presumably found no problems.  I received a robo-call today saying the problem had been "resolved".  I don't think anything has been changed, though---it's still slow as molasses every evening.

Given the fact that the slowness always occurs during what I assume are peak usage times, I'm guessing that it's some sort of congestion problem.  Anyone have any suggestions?

Thanks.

#1 What is the brand and model of your modem?

#2 What is the brand and model of your router?

#3 What software firewall is on your computer?

Thanks for the reply. I have a Westell Model 6100 modem/router.  I don't use any other routers.  I just run the firewall that comes with Windows XP SP2.

#1 If your Westell 6100 is the red and black firmware

For example as addressed on http://www.dslreports.com/faq/13600

go to System Monitoring -> Advanced Status -> Transciever Stats, and post that info.

#2 In the router, go to Advanced -> UPnP.

#3 If that feature is turned on, please turn that off.

#4 Is Wireless in the modem combo (modem and router all-in-one) enabled?

#5 If so, any wireless security set? For example, WEP/WPA.

#6 Does this happen at certain times with all server(s)/website(s) or only certain server(s)/website(s)?

#!:  My modem does indeed have the red and black firmware.  Here are the Transciever Stats:

Transceiver Statistics

Transceiver Revision:     7.2.3.0      
Vendor ID Code:              4      
Line Mode:                        G.DMT Mode      
Data Path:                         Interleaved      
 
Transceiver Information        Downstream Path     Upstream Path
DSL Speed (Kbits/Sec)         864                                160
Margin (dB)                              22.0                               31.0
Line Attenuation (dB)             36.5                               22.5
Transmit Power (dBm)          5.2                                 11.1

#2--3:  The UPnP is currently turned off.

#4--5:  No to both, AFAIK.  I don't see any way to enable wireless on this modem, or to turn on any wireless security.  I've never tried using wireless on this computer (it's about 6 years old, and I don't even think it has the required hardware). 

About a month ago, my neighbor in the apt complex did approach me offering to share the cost of a wireless connection if I already had one.  Heh.  I told him I didn't have wireless, though.

#6:  The slowing seems to happen with all websites that I use---my school email, various blogs, youtube.  I've been checking my speeds with speedtest.net, and the highest download speed I've gotten between 6 and 9 PM is 0.38 Mbps.  About 0.10--0.15 is more typical.  I've run the test with several different servers in my general region.

Thanks again for the assistance.

By looking at the one of sample screen(s) that are provided over there for that firmware, the router has the following options on top: Main, Wireless, My Network, Firewall Settings, Advanced, and System Monitoring.

The Wireless Settings, I would think would be at Wireless.

This applies that your router, does not have only: Main, My Network, Firewall Settings, Advanced, and System Monitoring.

As need be, if you do not understans what you see in Wireless - Show a screen shot of that area.

Thanks---the model 6100, which I have, doesn't have the "wireless" icon, as the dslreports page indicates just below the screenshot.  I've clicked around the various menus, and haven't seen anything pertaining to wireless settings. 

And I may have spoken too soon about the issue being solved, unfortunately.  Later last night and also this afternoon, speeds are dropping as before. 

Thanks for the continued help.

While you are not on FIOS, I wonder if your issue is somehow releated to this other thread

Thanks, I'm going to read through that thread and see what I can pick up.  FWIW, I just tried using tracert on google.com, verizon.net, etc, and the only "hop" that shows up is my dsl router; the rest time out.  I can't ping those sites either, I just get a time out message.

Ok, I set the firewall on my modem to "low" security, and now I can get tracert to work anyway, if that's useful to know.

What was it set to before you changed it to low?

Thanks for the response.  I've been away for the weekend, so I'm just checking in now.

It was set to "typical security (medium)" before, which is described as:

The medium security setting only allows basic Internet functionality by default, just like High level security. Medium security, however, allows customization through Port Forwarding configuration so certain traffic can pass.

I also now have my laptop, so I'll see if I still get slow speeds on that computer.

Well, changing to my laptop doesn't appear to make any difference.  According to speedtest.net, it's performing about the same as my desktop.  What's frustrating is that some sites, like this one, will load ok (albeit very slowly), but the ones I really need to use (my school's blackboard and email) load only partially, so I can't use them. 

The cyclical behavior continues like clockwork, with good speeds in mornings to early afternoons, and then slowing almost to a halt in the evenings, so I'm pretty certain it's not my system.

Here are some results I just got running pingplotter:

I've truncated the list of hops, but it looks like I'm having quite a bit of packet loss.  I let this session run a bit longer, and the PL% was up to 13% at hop #2.

Destination not reached in 35 hops

Around the time I ran these tests, I was getting about 0.44 Mbps download speeds according to speedtest.net, which is relatively "good" for me at this time of day, but only about 60% of what I should be getting.

When I ran pingplotter in the morning, my maximum PL% was around 2%.

Update:  I called in to support once more, describing the issue, and apparently something was done---the problem appears to be resolved.  I'm getting approximately 768 kbps download speeds at all times of the day it seems.  Thanks to those who assisted me.

Had a tech at my house on Wedsnesday, no line problems.. Called again tonight and the CO will call back Monday. I've been experiencing these slow speeds every evening for about a month. It's getting progressively worse too.

Update:  I think the problem is solved now.  My modem firewall was completely turned off.  After resetting it to the medium security setting, I'm getting speeds in the range of 0.50 to 0.60 Mbps, much better than before.  Thanks for the help.
