Perhaps it has IP connectivity but no DNS? I can't remember whether the Jupiter disc image has "ping" on it or not, but if so, plug in a USB keyboard, get the shell up, and see whether you can ping 209.10.41.70. Then see whether you can ping ecddb.gracenote.com.

It accesses CDDB on port 8080: check that outbound connections to this port are allowed.
