Put large furniture along the exterior walls of your home.

Minimize mirrors. All metallic surfaces reflect WiFi signals, including the thin metal layer found in most
mirrors.

Place your router in one of the following locations:

       Near the center of the house
       Off the floor, ideally on a high shelf
       As far as possible from your neighbor's Wi-Fi router (which, of course, you've made sure
        is using a different channel)
       Away from cordless phones and microwaves, which operate on the same 2.4-Ghz
        frequency.(There are some cordless phones that are Wi-Fi friendly)
       Keep antennas as far away from power cords and other computer wires as possible.
        Those cords and wires can interfere with radio reception.

Travelling

Set the adapter settings to maximize coverage (i.e, Power Mgmt. to Maximum, Transmit Power to
Maximum, and Throughput Enhancement to Enabled).

Turn off your adapter if no WiFi can be found anywhere. When you reach a town, turn it back on. You
will seem to find WiFi everywhere. Whether or not you can access it will be another thing.

Tips

       The computer case itself can be a significant barrier to the Wi-Fi signal - try positioning
        the case so it doesn't come between the network card and router antennas.
       The addition of a "high gain" (higher dBi) external antenna will often provide increased
        reception signal and performance. Note that a higher dBi increases the signal
        horizontally, but decreases vertically. If you need to cover several floors, a higher dBi
        will probably not help. In this case, you might consider buying a Wi-Fi amplifier, which
        will boost your signal.
       Reflectors can also be used to good advantage. Use NetStumbler to tune your placement
        of the reflector. Compact disks can be used, as can anything that actually looks like a
        parabolic reflector. The reflector, of course, should be placed behind the receiving device
        or antenna. Large increases in signal strength can be expected. This trick also works with
        cellphones.
       If all else fails, you can look into purchasing a WiFi repeater, which is a piece of
        hardware you can use to boost the signal between the router and your device.
       Depending on your brand and model of wireless router, you may be able to replace the
        built in software with a replacement open source solution that adds much more
        capabilities and the option to increase the power to your wireless antenna.
   If you still need more range, consider upgrading your wireless standard, up to Wireless N
    or Wireless G with MIMO. These two technologies will greatly increase the range of a
    formerly 802.11g or 802.11b network.
