The range is decent on the 936L.
What router are you using?
If line-of-site from the 936L camera to the router is like 1 or 2 walls without any interference or things like fish tanks and metal, mirrors, etc it should work fine.
Make sure you have the latest firmware installed. Try possibly resetting the camera and set up from scratch. If it still doesn't connect outside the room something is definitely wrong with that camera.
My 936L at home is around 60 feet on a different floor from my router and connects ok.
