Most of the time my internet speed is:
But I'm on a laptop that is pretty far away from the router, so sometimes it drops down to average speeds of 40, 20, or even 10 Mbps. I'm lucky :)
PS: I usually use http://speedtest.net to find my speed. It shows download, as well as upload speeds.
EDIT: Just realized, so does fast.com
A little slower :P but it's not going to be the same every time
Super fast. Thanks for your entry
