Yes he has, I understand a little about tweaking and helped him out with that. It didnt help though. I also had him run Sys. Mechanic Indust. with its cable modem tweaks and that didnt help either. When I ran the same program it helped me, so I dont think tweaking is the answer. Im thinking maybe bad cable modem, bad wireing, or they just have him caped wrong because he NEVER gets above 1000Kbps although it does fluctuate.
