It's connected to my network and uses it to connect to Picasa Web Albums and such like. Windows 8 can also see files on on it so I'm pretty much convinced that as far as that is concerned it is on the network.
It's just that the current app can't find it and I suspect that Panasonic don't really like supporting anything much older than a year. Evidence? I have a much older Panasonic PVR which had a minor sound fault. A lot of people reported it at the time and Panasonic promised a fix via a download. I actually had this promise, in person, from their UK base in the days when you could speak to them. Long story short, no update ever became available.
