text: limewire: what criteria do i go by when deciding which download will go fastest? the whole dsl/cable,t1,t3 thing is very confusing. this is referring to your connection speed to the internet.   if you are on dial up you select dial up.   you could select a higher speed connection but it is not going to trick it into going faster.   t1 and t3 connections are typically used in businesses.   dsl and cable are normally home use for the most part these days.   dsl is slower then cable.  i hope this helps.
