A better Website Copying Tool?

I spend a lot of time mobile and as a results I do not always have a stable connection. I however have a low end IT job that does require a lot of online research and so forth. A few weeks ago I remember that Internet Explorer used to have a nice feature to make a website available offline. While searching for a program to do something similar I stumbled upon WinHTTrack Website Copier but this has some serious issues. Firstly it seems to cap out at about 20kbs and will only do 1 page at a time. I need something that will actually let me use my connection to the fullest. Are there any ideas out there?
