My modem allows me to customize my line stats. I can't remember what it's called and I can't check now because I'm not home.
It basically lets me configure my line if I see my SNR is too low. I can adjust this between -10 and 10; -10 being the max stability, but sacrifice the line's speed, 10 being best performance.
So, if I disable this option entirely, my line syncs at 20-megs. This setting is current set to -2, which bumps my SNR to around 8 db as opposed to between 5 - 6 db. So my line is syncing, if memory serves, at 1.8mbps ATM, but I'm only getting 1.4mbps out of it![]()
There are line overheads for ADSL on top of the normal packet/ethernet overheads.
You are looking at about 10-15% of the line speed being used for it. So speedtest of 4Mbps is usually 3.2Mbs - 3.6Mbps. For 2Mbps it's 1.4Mbps - 1.8Mbps. All depends on copper quality/distance/exchange etc.
