Hi andy71 and welcome to Web Master World!

Waht you ask is a bit complicated, supposed you have a php script which you include in all pages, this script will grab the visitor's IP and ping it somehow, then according to the results you can figure out (approximately) if his connection is fast or not. But if your server is loaded by traffic at some point in time (i.e. caused byother websites located on the same server) then your 'ping' results will not be correct. This is just my frst thought, other ways should exist, but whatyou ask is a bit rare.

Hope the best
