Slow Connection and Random Disconnects (Transceiver Statistics Included)
Enthusiast - Level 1

I am on the 1.5 - 3Mbps plan, however my connection has been horrible. I am trying to look at an a few online video tutorials and the buffering makes it unbearable. I called Verizon a few months ago and changed my modem, however the issue persist.

The internet speed seems to fluctuate. Here are sample speed tests within a 5 minute time frame:


Test 1:

Your downloadspeed is 0.571 Mbps.

Your uploadspeed is 0.432 Mbps.


Your downloadspeed is 0.367 Mbps.

Your uploadspeed is0.453 Mbps.

Test 3:

Your downloadspeed is 1.143 Mbps.

Your uploadspeed is 0.448 Mbps.

To be honest, you either have a lousy copper pair, or you are a long way from the Central Office (CO). The losses in your line are very high, and that is limiting the speed to considerably less than 3mbps/768kbps that should be available to you. My other observation is that when losses are that high, the speed of the link tends to change quite literally with the weather. When I had DSL (I have FiOS now), the downlink varied by as much as 600kbps depending upon the weather, and if I could hear thunder, my DSL service was down...

You haven't mentioned what Operating System your computer uses. If it is Windows7, you can expect that repeated speed tests will cause the downlink speed to slowly improve as it dynamically increases the receive buffers.

The other thing you probably should do is run, and see what it says in the statistics and the 'more details' tabs. The issue is either the link to the CO, or network congestion upstream from the Central office.

 Your uplink speed is pretty much the best you can hope for with the copper pair you have.

Thank you for your response. I do not know how far I am from the CO (I am @ 22204). I am using OSX and Win7 and the results are about the same. I ran the test you suggested, but the speed is fine at the moment (1.5 Mbps). I will run it again tomorrow when the problem returns.

Thank you

If you give Verizon a call, ask the rep on the phone to give you the length of the line in feet. Most of the time the representitive can perform an MLT test on the line or look at the database for your loop length.
