I have been calling my ISP (AT&T Unfortunately, that traceroute only indicates that the problem is somewhere between hops 1 and 2. 1 is your router and 2 is probably your ISP's DSLAM. If your ISP has even half a clue, the statistics of your line on the DSLAM are telling them much the same thing as your traceroute results. That's probably why they are willing to send a tech to you: they already see that your line definitely has a problem. https://en.wikipedia.org/wiki/Digital_subscriber_line_access_multiplexer If there's about three miles of wire between your router and the DSLAM, then 3 Mbit/s would be about the best the ADSL2+ technology can do. But your trace looks like your connection is somehow unstable: that should not happen unless there is a problem on the line. Is your line only for DSL, or do you have a plain old landline telephone using the same line? If you have a landline, pick up the handset and listen: is the dialtone about as loud as usual, or is the volume too low? Is there any hissing or crackling in the background? (If the tech is an old-school telephone lineman, he might be a bit out of his depth with all the new-fangled DSL stuff. If the problem is detectable on the telephone, describing those symptoms might get the tech thinking about the problem the right way.) Here are some things you can check at your end, although I guess you may have already done those: https://mrtelco.com/blog/top-5-common-phone-line-faults-affecting-landline-adsl As your line is probably pretty long, you'll want to minimize the number of splices and other connectors between the router and the line entering the house. Your router might be able to show you some line statistics, similar to this: http://www.kitz.co.uk/adsl/linestats.htm In particular, the signal/noise ratio and the line/signal attenuation would be the most important statistics: if the attenuation is high, your router will be sending the digital equivalent of "can't hear you, speak up!" to the DSLAM (and/or vice versa) every now and then. And if the other end is already sending at full power, it cannot compensate for the attenuation by increasing the power. If the SNR is low, there is a lot of background noise on the line, interfering with the data transfer. If your line is on telephone poles (i.e. not underground), you should make sure there are no tree branches rubbing on the wire/cable. If the line is underground, you'll need a tech with TDR equipment to locate any faults on the line. https://en.wikipedia.org/wiki/Time-domain_reflectometry

) a few days ago and they are going to be sending a tech guy for the umpteenth time to "Check out my line". Can I show this to the guy so he can accurately determine where my problem is coming from? A few weeks ago things were fairly good as I could do all of my work online with no worries. Even games. Then a few days ago nothing in my online classes would work and it's driving me up the wall.
