Dear All, 

    I have a building, out of my home. Outside the building the WiFi signal, coming from my home is very good, but this building is underground and the walls have a lot of shielding iron so that the signal inside is very poor.
I would like to take the external wifi-signal and bring it inside with a cat-5 cable connected with an access point inside.
To do this I need some outdoor router or maybe an outdoor range extender with an RJ45 port, or a router with an external antenna but I am not able to find such device. Have you some suggestion?

Thank you.
