I'm logged into the FiOS router and tried to manually assign a static IP to the Slingbox - I'm getting a "lease expired" message every time I try.

To be clear, I only have one drop in the living room. When I only had a TV, I used the drop to connect to the internet via the wired connection. Once I got the Slingbox, I decided to use the drop for the Slingbox and used the wireless adapter on the TV for that connection.

I just connected the Slingbox directly into the FiOS router and it seemed to connect to the static IP I set up (I assigned the Mac ID from the box the Slingbox came in). I then took it to the living room and plugged it in there and the IP is now showing as "expired" in my router. I did check to ensure UnPnP is enabled.
