DSL Connectivity Issues, Verizon Useless

Apophis · 08-03-2006, 12:51 PM

I've contacted Verizon Tech Support many times, but I've almost always gotten some Middle Eastern guy who has me turn off my computer and modem, turn them back on, see if I can access a website at that moment, and then tell me my problem is fixed. Last week, I actually got someone who was helpful and elevated the trouble ticket, only to have them halve my connection speed and close the ticket without the problem's being solved.

Sometimes, I experience long periods where the connection is repeatedly lost and regained. Between drops I see the following symptoms:

Always: Significant decrease in the downstream's noise margin, and rapidly accumulating CRC errors and invalid/dropped cells.

Sometimes: Slight decrease in the upstream's noise margin.

Infrequently: increase in the downstream line attenuation by between 1 and 6 dBm.

What is causing this and how do I fix it?

It seems clear it's an issue with the modem or Verizon's lines. Other than try a new modem, there's not a lot you can do. One thing I suggest for DSL is better wiring, here's my RX for poor interior wiring.

Purchase a DSL splitter and install it at the telco service entrance. Run a direct line from the DSL port on the splitter directly to the DSL modem. Connect all of the other phone instruments to the telephone output of the DSL splitter.

This is as good as it gets for DSL installations, and will usually solve in-house wiring issues.
