Someone gave me a Belkin Router but the PS is missing will this work?

This one is version 1111. My current router is nearly identical but smaller and only one
antenna. It's been a real champ for a long time, I'm just trying to get some extra signal
on both ends of the house. I think I'll splice tomorrow. Now watch the hole in the center
of the plug be too large make contact with the pin in the router.
