If you too have a problem getting Wi-Fi signals in every corner of your house, here are some tips (and accessories) to help you extend the range of your wireless network.
#1. Install the DD-WRT firmware on your wireless router – this might help increase the range of your Wi-Fi router by a few meters if not more.
To increase the signal strength, you can increase the router’s transmit power and also disable both frame burst and afterburner (the settings can be accessed from the router’s web dashboard). If DD-WRT firmware is not available for your router, try the Tomato firmware on your router.
#2. Most routers have omni-directional antennas so they emit wireless signals in all directions (just like a light bulb).
That’s fine if you have placed the router in a central location but if the router is in some corner of your room or against a wall, consider adding a home-made reflectorbehind the antennas of your router.
#3. InSSIDer is a free utility that can help you detect the presence and strength of wireless networks. Install InSSIDer on your laptop, walk around the house with your laptop to determine the wireless signal strength at various places and, based on this information, you can quickly find a more suitable location for the router.
#4. Ideally, you should place the router at a height in some central location and away from other cordless devices. Make sure that the router is not placed near something metallic (like an almirah or window grills) as that will weaken the wireless signals. Avoid mirrors as they can reflect the wireless signals away from the desired direction.
#5. Wireless routers generally ship with omni-directional antennas but you can replace them with more powerful uni-directional antennas and that will keep the signal from getting broadcast in all directions.
If you can’t find a compatible directional antenna for your router model, consider a booster antenna that’s omni-directional but will still boost both the range and strength of wireless signals.
