Sorry but what is a "gateway"?   can you not just put ali foil over it?  It will block almost any waves and does not over heat easily. The problem if you do not live in a remote location is that there are so many sources of MWs.  The UK has the most powerful BT wifi in the world every where. They are proud of it. 500m. In France it can hardly cross a room.  Even if you switch your box off it will come in down the phone line and all your power cables.  Ferrite chokes help. Little clip ons. 5 for a £ on eBay.

Fingers crossed.
