Um for what?

Dialup
Cable
DSL
Local Intranet
?????
if its dialup just hang your mouse over the little dialup monitor down in the system tray while yer connected, most 56K modems will get about 46,000 buad to 49,000 (if you see something like 115,000, or higher, this isnt your internet speed, but your Computer to Modem Speed)
