I've tried everything! Just cannot seem to get above about 10k no matter what I do.

Contacted LW support and they say that the newest version works the same as the old so nothing should change vis-a-vis download speeds. If this is true, then I guess everyone is just setting their upload bandwidth limits really slow.

Who knows...

ETA: for example, I am now downloading a file shared by 54 hosts, connected to 8 hosts and I'm getting a whopping 14k!
