I guess it depends on what speed your DSL plan is. For an idea about the speed settings within LW see: 1. What speeds are T1/T3, etc. for LW & 2. More on LW connection speeds

Go to LW's menu Tools>Options>Speed/Downlds/Uplds>Basic to make changes you feel necessary. For some hints see Optimising LW & Maximising Uplds & Dwnlds (Murasame can help you there!) & some other tips & skills you might find interesting & useful see To continue files downlding (click on link)
