Please advise, how do I setup network connectivity over wire?

I'd try a known good cable as a start.
I don't think the Play 1 has lights on the Ethernet port, can't get to either of mine right now to verify that. Still your router or switch should have lights and show a 100 MHz connection (usually yellow) when the Sonos is plugged into the port.
If a known good cable doesn't work after you power cycle the Play 1 I'd phone in to Sonos support to see about getting a working unit.
You should see some Ethernet stats: (just use your IP address to replace mine)
