Looking for coupler that would have female inputs at both ends. My MIL travels to several time share resorts that have only wired internet. The ethernet they supply is permanently connected at one end and the other end plugs in to her laptop. The cables tend to be short, forcing her to sit at a counter. This is uncomfortable for her. I am trying to locate a coupler so that she can plug an additional ethernet cable in so she can sit at a more comfortable position.

I have tried searching several websites and the web in general and cannot find this. I would think it does exist.

Any ideas on where this might be?
