I have a splitter on my line however it is wired approx 10-15 meters away from where the line comes into the house, on what I presume is the first phone jack point.
I am getting 4mbp down and 600kbps up my modem is connected at 4mb.  Out west in Blockhouse Bay.
If I move this first jack point to the entry point of the cable into the house and plug the ADSL modem into it will this give the modem the best chance of negotiating a higher connect speed?  And will it still matter how many jack points and devices are connected after this first jack point?
