Were you not aware that the broadband was likely to be dire before you moved?
Yes and no.
I'd heard anecdotal stories of "terrible" broadband in the area, but I tend to take that with a pinch of salt as a lot of people don't really understand the difference between a good and poor connection anyway.
I spoke to BT & looked online at the speed estimators and they suggested 1-3.5Mbps - somewhere in the middle of that isn't exactly fast, but would've been adequate.
I'm trying to be pragmatic and get the best out of what I have.
That isn't any indication of the likely speed on a line that could be above 75db!
Absolutely
It's been suggested they run G.INP on their ADSL product which might help... quite a bit
It may be worth ordering a complete line+DSL with them. Don't cancel your existing. Let them manage the entire process. This will possibly highlight the availability of spare pairs in your area (or not) and will also give Sky some flexibility to bin the line if it's completely hopeless, perhaps. There's a 30 day period from point of install where whinging is taken seriously, I believe?
A new line + broadband from Sky is a min 12 month contract which is £286. Thats a lot of money to try just as a test!
(but the actual ongoing cost, if less than £30-£40 a month is basically irrelevant if it's any better!)
I'll do some more research into LLU long lines / Sky etc - but in the meantime I'll keep dropping my SNR and then try manually specifying the ADSL mode so that I have a solid benchmark and hopefully some more accurate line stats.
