Remember that line speed estimates are hugely conservative, and also depend on sync speeds of those in the area. If cabling is of a low standard then sync will be very low. In my postcode we're only supposed to get 4-5Mb but with a decent modem (Netgear DG384 with DGTeam firmware) I can lower the SNR target so I'm syncing at the full 8Mb limit for ADSL2. When I first put in the new modem the line would sync at 5Mb; now it has been syncing at 8Mb for a while the line will sync at 7Mb with no target SNR tweaking. www.kitz.co.uk has a lot of useful information about broadband, and well worth a read.
