I am having disconnect problems with my DNR-202L as well. I just purchased it a few months ago, and immediately started having trouble with it disconnecting from the network after a few hours (red x in mydlink) I have replaced the Ethernet cable, set up static IP, and replaced the router with no help. My cameras are having no issues - just the DNR-202L disconnecting after a few hours. I have to do a power cycle to get it to reconnect, sometimes twice, which defeats the purpose of having the network recorder as it isn't recording after disconnecting.
