Yes...I experience this practically daily lately. I go through the normal setup process, enter the code, then allow the extender to refresh my media files. All works well until the next time I turn it on. Sometimes it will go directly to the setup screen, other times with will try to connect to my PC, then say "Cannot connect to PC", then the setup screen appears.
I have a Dlink DSM-750, I don't have the FW version handy, but it is the original firmware that came with the unit (this is my second unit...my first had the security certificate corruption issue, so Dlink replaced it)
This does not happen all the time....lately it has, but I would consider it random. Sometimes, if I leave the unit off for an extended period, it will work the next time I turn it on.
I never lost the connection. When I power off, I typically do so via the remote.
I am using Vista Ultimate 32bit, SP1, 4GB ram
I connect to my PC via ethernet through an Actiontec router provided by Verizon FIOS.
Hope this helps!
