I've been using LW for a long time now but only on a dial-up connection. About a two months ago I upgraded to a cable connetction and I still have very slow downloads. I can download things from Internet Explorer just fine and at blazing speeds. Here is some system information you may need:

1. Windows XP OS
2. windows firewall with LW as an exception
3. 512 MB of RAM
4. 50+ GB hard drive space available
5. cable internet
6. motorolla SURFboard SB5101
7. connecting from home
8. LW 4.12.11 Java 1.6.0_01
9. Metrocast cablevision
10. "YOUR TEST WORKED"
11. no
12. On going problem with experienced user
13. no brick wall on LW interface

5676 kbps download test
366 kbps upload test

Im thinking that since my downloads from Internet Explorer are fine and my LW downloads are so bad that maybe Metrocast was shaping my connection. But my buddy uses the same provider and actually has a crappier computer than I do, but he downloads at over 60 KB/s, I on the other hand am lucky to get 10 KB/s.
