Does anyone else have a problem with the DSM-520 disconnecting on idle? I'm using the DSM-520 over an 802.11g wireless connection to JRiver Media Center's UPnP server. The DSM-520 consistently disconnects after it's been idle for a certain amount of time (15 minutes?). When I start using the DSM-520 again, it takes me to the "Server Connect" screen, where I can always reconnect. We don't have any 2.4Ghz phones and the microwave isn't between the AP and the DSM-520 (and there doesn't seem to be a correlation). My connection strength hovers around 80%.
I've also tried the TwonkyMedia 3.1 UPnP server, and it actually disconnects while browsing menus. I haven't had any problems streaming music or video with the JRMC UPnP server.
I noticed that DLink fixed a similar problem in one of the DSM-320 firmware upgrades. Anyone else having this problem with the DSM-520? What UPnP server are you using?
