    I need some help trying to pin down what it causing my latency to go sky high. This only happens about once an hour and I have yet to find a pattern to this madness. I have replaced the modem, installed new cat-5 cable from the NID to the modem. I can replicate this on multiple computers, including a centurylink tech's laptop (he was stumped by the way). Any idea's would be appreciated.

    Ask Century-Link to move you to another DSLAM and see if that gets the kinks out.
    I had a customer with similar, only worse, issues last Summer.
    I had to PROVE to CL that is was on their side.

    There's something wrong with that DSLAM. 2 second latency first 3 hops out? Whoa.

    I love the email response from them.

    "honestly this line is never going to be perfect. If you are looking for more stability I would recommend a T1 line or something other than a $45/mo residential DSL line. At least with a T1 it’s dedicated from the box and usually doesn’t suffer the same fluctuations as other services."

    I guess that this is just normal and everybody's connection does this :nono2:

    Dumb question..Did you recently have your pairs swapped out? (telephone line)They may have replaced it with a pair that has "bridge tap" which in laymans terms is "extra wire" on telephone line when a pair (of copper wires) is used to service 2 locations.(its possible they forgot to remove). It sounds like (based on your symptoms) that your current copper pairs maybe "too long" (thus causing latency)for DSL service but would work just fine for regular telephone service..just a thought..also if you have caller id ..does it work all the time?

    No bridge on the line & I'm about 500ft from a fiber dslam so distance is not a problem. If you look at my line stats I posted, they are about as good as you can get. Also I don't have traditional telephone service with them.

    Do you know how big the trunk to the DSLAM is? One of your "neighbors" could be downloading a movie and hogging all the bandwidth. It really does sound like the DSL tech (on the Phone) knows the answer and maybe just maybe they have oversold DSL service for your particular neighborhood. The trunk could be anywhere from a T-1 to a OC-3 depending how "cheap" the DSL buildout was

    There are two possible DSLAMS that I can get service from, one is T1 and the other is fiber (can't be any more specific then that). I don't think that it is over sold because I have not had a drop in speed, my samknows router confirms that. But it does log that my latency spikes.

    I currently get service from the fiber Dslam because they have the 12 & 20mbps plans on that, and the T1 serves 1.5 & 7mpbs.

    When I had a tech out to take a look at the lines, he said I got a used adsl2 dlsam from when they upgraded another dslam to VDSL that is 3 blocks away and that my dslam is getting up there in age (about 7 years old). The tech said if I could get proof that it was going south that he could get it replaced, but here is the kicker. When centurylink bought Qwest, the tech's very good benefit package went away, so they gave all of the tech's a choice, leave now with your old package or stay and go with ours. My tech left and so I'm out on that front. I have tried to bring this up with other techs, but none can replace it because my local's office budget was cut by almost 80%. And because I'm not an emergency, I'm not getting a new dslam in a long time. I was told that if I can get more people to complain about this, they would swap it out but that's going no where.

    And with the stunt I had with comcast, they no longer want to return to install internet, I'm stuck with centurylink. I just with that my city back in 2001 would not have shot down the utopia ftth project.

    kiknwing we have your info and took a look at it and will have a tech out to check the port 9:30-1:30 Monday to work on it and test it. You will not need to be home during this outside visit.

    thanks,

    Oops... Make sure that this was not cancelled. I got an email about an hour before you posted here and I forwarded the email to someone in the boise office thinking there was a mistake. I contacted billing earlier in the day and thought somehow someone hit the wrong button.

    Two posts in two years! The first was a reply to my qHome question. The Mods need to change their name to "TalkToCenturyLink"
