Depending on which bandwidth test that I run, and the time of day that I run them, I may, for example, achieve the following results:
1) dslreports bandwidth test: downstream: 15Mbps
2) Q1000 DSL modem configurator: downstream: 25Mbps
3) digitalconcerthall (an online video streaming service): downstream: 5Mbps
The above are results for "prime time" and represent a period that digitalconcerthall cannot be streamed without frequent periodic interruptions (e.g. 30-seconds apart). Outside of this time window, however, the rates reported by 1 and 3 above are significantly higher (e.g. 22Mbps and 11Mbps, respectively), and digitalconcerthall can stream satisfactorily. I have no trouble streaming from Amazon or Netflix regardless of the time of the day. My questions are:
1) Why does the Q1000 configurator consistently report 25Mbps, even when the other tests report significantly different results?
2) Why does the time of day make a difference, and why is digitalconcerthall problematic, whereas Amazon and Netflix are not? (I am in AZ, and the nearest digitalconcerthall server is in CA)
3) Why are the bandwidth results for each test so different from each other? Which test is the most meaningful?
4) When I invoke digital concert hall application on our blu-ray player, the quality of the download will be consistent for the entire session. It will either be perfect, or it will be interrupted/paused at periodic intervals. The performance neither degrades or improves for a session. Is this because the bandwidth of this connection is negotiated and maintained when I use the application?
5) This issue began in early December after months of perfection with digitalconcerthall at all. What are the reasons that such a problem could just begin after months of flawless performance? (I realize that answers will require educated speculation.)
(I am also in communication with digitalconcerthall, who is suggesting, "try this," and "try that" with no change. I have a single, non-bonded, line.)
