Mine is messed up now. I should be getting 3 MB/768 K less about 10% overhead and I have in the past.
Last issue was the protector in the NID. I'm also running without a 1/2 ringer in the NID. The NID also has an Autojack. The loop of silver satin cable, which is bad doesn't exist. The 1/2 ringer is a bad thing.
I'm getting around 0.6 Mb/s down right now. Not good. Troubleshooting is a real pain since I run the DSL modem in "Bridge mode". The ISP can't trouble shoot unless it's out of "Bridge mode". My laptop is connected wired only for troubleshooting and configuring devices.
As for Hitech, he probably isn't running XP. You have to hack the registry to get XP to even run that fast. At work I had like a 48 Mb/s link. It, however was a Windows/machine limitation, not a link limitation.
