I know this is an old post, but I didn't see the solution that worked for me listed anywhere near the top of any search results for this issue. I was having the same problems, incredibly slow download speeds. I tried all the suggestions of editing the launcher.settings file, but none of those worked for me. What I finally found was this utility (official EA guide link) that repairs the launcher. After placing the .EXE in my SWTOR install folder and running it, I'm downloading at full bandwidth. Hope this helps someone.
