Fixing a NSLU2

I'm running an NSLU2 server with the default linksys firmware. It serves up a USB hard drive to my home network. It was failing sending small files in Windows with the message "The Network name was no longer available". I just disabled UPnP support on the NSLU2 and then file transfers starting working. I found this tip here http://www.nslu2-linux.org/wiki/FAQ/DroppingConnections.
