Sorry, it can't be done. Unless you know the last network it was connected to and you can configure your network to match you're out of luck. On the off chance it's a model with an Ethernet jack you may be able to connect it with an Ethernet cable, but I'm not even sure that would work.
P.S. - cheap universal remotes can be found almost anywhere, but they will only work on models that aren't sticks that plug directly into your TV without any cable.
