Extremely slow and failed backups to Box.net

Downloading is slow and failed for large folder Hi When I try to download folder from my box account (~700Mo) it is extremely slow (max 150Ko/s) and fail before the end (around 300Mo downloaded). How can I fix that ? I check for my connection and I’m able to download big file form other website at very high speed (~100Mo in less than 30sec on Brother website for example)
