My official download speed taken from PC Pitstop is at:
Download speed: 4325 kilobits per second
Don't know why it hasn't gone up to the 6 Megs like Comcast said. I got a nice little post card from them saying that my bandwidth has been increased to 4 Megs instead of 4 Megs. Hmmm...
I'm not too sure how your cable networks work over there, but my provider (NTL, UK) recently gave me a free speed upgrade which didn't seem to kick in. I disconnected the modem from the cable and turned it off. Then hooked it all back up and it now runs at the faster, upgraded speed. Something you could try maybe?
See thats where you and me differ Dave, I like downloading things, Gimme gimme, but you like uploading, whats yours is the worlds, lol your too giving! Its not right! lol
