In my application, the requirement was the Wi-Fi coverage to another floor to expand (router on the top floor, all wireless subscribers in the lower level), with a reinforced concrete slab was overcome.
The establishment of the repeater is no special technical knowledge possible if the router supports WPS procedures Pushbutton "mode. In this case, routers and repeaters must be installed in close proximity. By means of a button (WPS button on the router and button on the repeater) takes place . then the coupling The widespread Routers Telekom (Speedport) and AVM (Fritzbox) are WPS-capable and therefore suitable for the repeater If WPS is not supported by the router, can be configured manually -. However, this requires at least a basic understanding of technology ,
One should pay attention to the well-known pitfalls:
1) Repeater possible position at one point, which is about halfway between the router and the potential wireless subscribers. The Repater must at least receive a mediocre signal from the router. In overcoming levels of repeaters on the stairs or in the stairwell should be installed because here max. Passage "exists.
2) The maximum transferable data rate halved (Wi-Fi is a shared medium) because the repeater transmit simultaneously and must receive.
3) Some routers Problems can arise if, in the configuration (coupling) MAC access restriction is activated.
Avoid 4) the simultaneous operation of the repeater and a Powerline adapter on adjacent sockets.
