The power output of most routers cannot be altered, so even though a lengthier external antenna may work around objects better, it won't magnify the power output. However, you may experience significantly improved results by changing the antenna type. Most wireless routers use an omnidirectional antenna to broadcast their wireless signals in all directions. If the router is situated near an exterior wall, the signal that is broadcasted through the wall is wasted and exposes your network to potential hackers. By connecting a directional antenna, you eliminate this wasted signal and focus the limited power in the direction you need it most, which effectively increases the signal strength in that direction.
Unscrew the existing antenna in a counter-clockwise direction at its base until the antenna separates from the router. Antenna Mimo
Screw the new external antenna onto the same connection stud using a clockwise rotation until the connecting ring will not turn any further.
Orient the router or antenna so that the signal is emitted in the direction of your wireless devices. If this direction is not obvious by looking at the antenna, consult its instruction manual for details. If you are connecting another omnidirectional antenna, you don't need to worry about direction, but be sure to position the router away from large obstructions, such as metal filing cabinets or brick walls. Such obstructions will dramatically dampen the strength of your signal.
