Do not locate the router on the floor and keep it away from walls and metal objects
Avoid placing the router near objects such as metal filing cabinets. Metal objects, walls, and floors
will interfere with your router's wireless signal. The closer your router is to these obstructions, the
more severe the interference, and the weaker the signal.
Reduce wireless interference
The most common wireless technology, 802.11g (wireless-G), operates at a frequency of 2.4GHz. Many
cordless phones, microwave ovens, baby monitors, garage doors, and other wireless devices also use
this frequency. Reduce interference by avoiding wireless devices that use the 2.4GHz frequency and
use devices that communicate via the 5.0 GHz frequency instead.
Replace your router's antenna
If you must place your router in the corner, consider replacing your standard antenna with a Hi-Gain
wireless antenna.
High gain antennas can be attached to most wireless routers. They boost the signal strength and aim
the signal in one direction.
