I've been connected in this new place for roughly 2 months now and up to now I'd say that my DSL (or is it adsl) would remain stable for the better part of weeks at a time. But now, since late last week, I'm lucky if the DSL light stays up for a couple of hours at a time.
I thought maybe the modem was overheating, so I opened it up and directed some airflow at the hottest chip on there. It felt like it was helping, but that impression lasted about a day before there was nothing doing anymore. So I got another modem and ditto.
Now, looking into things a bit deeper, it looks like my SNR is bloody terrible with whichever modem I use. It's usually in the 6-7 range so I suppose that's the actual problem.
In between outages I've managed to read online that humidity or other environmental variables can have an impact on signal quality, so maybe I'm experiencing a daily cycle of better/worse signal conditions which I can't quite put my finger on yet. Or maybe neighborhood bandwidth usage has something to do with it. Dunno.
Anyway. I'm looking at some other connection stats and reading up on them and came across this somewhere "Output Power: Indicates how much power each modem is using. You will see power increase as loop length increases. Additionally, sync frequently becomes unstable when output power is > 15-16dB" mine is sitting at 11/13.5 (up/down). What I'm wondering is what kind of loop length are we talking about here? Is this the kind of thing which is counted in miles or in tens or hundreds of yards. Could I see a substantial improvement by splicing into the line right when it gets to my door instead of jacking in at the end of a lengthy, house-girdling run of unknown quality wire?
TL;DR: Has anybody seen substantial improvement in either SNR or Output Power by connecting their DSL modem closer to the phone line's point of entry into their home?
