I tried to figured this things out...and this is my observations:
The advanced commands only made your connection speed lookt 115, but you're still on the same rate that ranges from 3.6 to 5.6 or 7kbps.
This doesn't actually work since it only REPLACES the numbers show by multiplying it by 2.04 it doenst really do anything but that. Your ISP is the one that controls your NET CONNECTION SPEED, if they only set you to get and gain max of 44-50 kb's then you are stuck there no MATTER WHAT! even with this tweak, it will say 115.2 but it is actually connected at your usual rate.
Try to use a internet speedchecker and you will see the exact speed of your connection...still the same and no changes...
