Turn Your Old Router into a Range-Boosting Wi-Fi Repeater

Turn Your Old Router into a Range-Boosting Wi-Fi Repeater
Our suggestion is to installed the open-source DD-WRT firmware on your router and turn it into a repeater for your main router, expanding your Wi-Fi signal to reach every nook and cranny of your house, and even into your backyard or garage, if needed. You'll be able to use the same password and security scheme, you won't need anything except a power outlet for the repeater when you're done, and most of your devices will automatically switch between the two signals when needed.
