| [Speed Problem] DSL Direct Pro slow at night only I have AT&T DSL Direct Pro 6MB service. The speed is wonderful at 5MB every day from the morning through dinnertime (around 6PM), at which time the speed drops to under 1MB. This happens every day - Monday through Sunday - with complete repeatability. Every morning (when no one in the neighborhood is streaming Netflix, playing MMORPG's, etc.), the DSL speed is back to 6MB (5MB measured).
It's DSL Direct - no dial tone, no splitters needed. Direct hard copper JK wire from the telco POC/demark to the modem. Line noise is nil, the neighborhood is served by a fiber box.
My modem is a Speedstream 4100b, the router is a Netgear WNDR3700. Everything is fine until the evening, so the problem does not appear to be in my equipment or inside wire.
The AT&T Direct forum requires a post here before engaging in that forum. If there's anything I've overlooked, please advise and thank you very much!! |

Castro Valley, CA | That happens to me sometimes as well. It seems especially bad tonight, though.
I have dial tone, though (not direct). No inside wiring problems at all, DSL splitter is outside, Cat 5 line from there to the modem, no difference between connecting at the NID jack vs. connecting at my wall jack, so that rules out inside wiring.
I'm pretty sure I've isolated the problem to noise caused by AM radio stations. That would make sense that it only happens at night: AM radio signals go farther and are stronger at night.
It might also be dimmer lights, or other "noisy" lights, in your neighborhood. Those obviously will be off by day but on at night.
It's hard to tell where the problem is coming from, though. One thing you can try is connect at your NID jack, to rule out your inside wiring. Or, try turning off all the lights in your house and then restart the modem, to rule out lights (at least the lights under your control!) as a possible source of interference.
I ended up not solving my problem, but putting toroid chokes around my power cord (and to a lesser extent, the phone line's cord as well) seemed to knock out some of the interference. |
