Increasing your router’s power or purchasing an antenna will improve the signal to noise ratio at the receiver. You may have given up on laptops or desktops but you probably still have wireless for your tablet, smartTV and other devices. Although you may be surfing the web and thinking you are getting an excellent download speed, you may be able to increase the speed by using a third party firmware such as DD-WRT or Tomato. Traditional factory firmware usually doesn’t allow increasing your power.
First off you need to download Xirrus, NetSurveyor, inSSIDer or Vistumbler. Each of these free software packages allow you to measure your signal strength, quality and view the channel to make sure you are using a free channel.
Next relocate your router to other areas in your home or business.
Firmware such as Tomato or DD-WRT offer a power setting (below).
Note: It is important to make sure your router has adequate cooling and to only increase Transmit Power when necessary and in small increments. Always research your router and see what settings have been used to tweak your connection.
