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.
