I just posted a new Topic about this before I read this one. I just got the Mach 7 upgrade. My internet connection was still the same (slow). I had RCN replace my Toshiba PCX1100 and the speeds improved a little, but not much. I decided to disconnect temporarily) my Linksys router and the download speed jumped to Mach 7 speed. The Links router was my problem. Any suggestions on what software changes I need to make to the Router, or do I need to replace it. As soon as I hook the Linksys router back up, my speed drops.
if it's anything like my linksys router, make sure you aren't putting your computer into DMZ mode. for some reason whenever i attempt to do that (sometimes i'm too lazy to assign ports) my speeds drop from ~6000/800 to ~1500/800. no reason, no explanation, so i just avoid it.
