No, I do not use a USB connection to my modem. It is ethernet.

No, I don't use the resume button. I will occasionally use the search for more connections. LW seems to spend a lot of time idle i.e. the files are in the list, but not downloading because it needs more nodes. Even when I have three or four available connections, the dl'd speed hovers around 1 or 2, although I have seen it go as high as 38 on rare occasion.
