Hey, PastorP!
Excellent program! I tried it, along with others, before Cavtel told me that I was spinning my wheels and waisting my time for nothing as I'm capped at 2Mbps and 1.3Mbps is my fastest reasonable speed according to Cavalier. DrTCP didn't do anything for me but I hear others have had great results.
While I was driving myself nuts thinking I could get more than 1.3Mbps with Cavtel's "UP TO 10Mbps" sales gimmick, here are some great DSL tip sites that I found that have other good tips as well:
http://www.homephonewiring.com/materials.html
This site gives many good tips on optimized phone wiring for DSL. I was going to drop $44.00 on the ASDL2+ and POTS splitter as my wiring is "home run" and I can create a dedicated DSL jack. I did some experimenting, such as running straight from my NID to the Cavtel router, to see if speed would increase. Didn't make a difference when I reconnected my phones into the wiring so I saved my money. I would buy this splitter if I had real "high speed" ADSL2+ service with digital TV for it would save $$$$ on not having to have a filter on each phone and prevent "mirroring" and whanot when the DSL signal is fed to all jacks .... and wall plate ADSL filters aren't easy to find and they cost $15.00 when I do find them so this little $44 jewel would save money if you have many phone extensions in your home (four or more), which can degrade DSL performance.

Seems to be a good site for non-nonsense discussion on what will -- and what won't -- increase DSL speed.

Geared to BellSouth but has some excellent, general DSL discussions. Note that BellSouth is a different type of network than Cavtel (PPPoE versus TCPIP) and so some discussions, like changing the network MTU settings in a router, may not apply.
