Hi. We are renting an apartment in a comercial building and we are sharing a fiber connection with the house. The router is about 30 meters from the apartment and its not an option to connect our deco mesh via cable to the router and all our meshes and gear have to be in the apartment. 

The current solution as the subject says, the extender is wirelessly connected to the house router and the mesh is connected to the extender. This works ok but with the current extender we loose allot of speed and the connection is often interrupted. 

Wondering if there is a better solution or an extender better suited for the situation, we just had the TL-WA850RE laying around so figured it was a good idea to use it to test the idea.
