I have a technician scheduled for Friday morning who should hopefully be end-of-the-line for my DSL struggles, for now. A new modem arrived day before yesterday and I got it hooked up after work promptly. I logged in, set it up, and configured my wireless. I checked the status page, and the SNR (Signal-to-Noise Ratio) was still at 5.8 for upload. 6 is what manufacturers rate minimum just to get a sync. Below that, definitely should all the time experience problems. Not sure why Verizon tech’s line tests never pick that up. The modem reports attenuation is fine, but the SNR is terrible. Same with the new modem, using only cords and cables that came in the modem package and my wall jack.
So, there’s an issue with the line. Hopefully I can convince the tech that and he’ll do what needs to be done. I was told on the phone by a Tier 3 tech that they can run a line directly to the jack you intend to use the DSL modem from, and this usually eliminates the majority of signal issues.
