yes.

If for example it says 56k, its gunna take ages to download the item as the person your downloading it off has a very slow connection, doesnt matter if yours is fast it will still be slow!

So try to download from someone with cable or as you said above, t3 t1

Little tip, go into limewires options and in there somewhere you can set it so that whenever you search for something, it will only return stuff from people with a fast connection, only slight downside is that you might not have as many results.

Hope that helps
