This small tool will give you an estimate of the maximum speed your line can support on an ADSL2+ service. You will need to obtain the "Downstream Attenuation" figure to continue. This can be obtained from your modem/router configuration pages.

Please NOTE: If you are already on an ADSL2+ service, there is no point in using this checker. It is only for people on standard ADSL (including ADSL Max 8 Mbps).
