If you're upgrading to a faster, stronger wireless router, don't chuck your older Wi-Fi box. With the magic of DD-WRT, you can turn your older wireless router into a range-expanding Wi-Fi repeater to cover everywhere you need a connection.
The advent of wireless home networks grew slowly in the past decade, but reached the point at which nearly every home with a high-speed connection had a wireless router that shared Wi-Fi connections throughout the home. Now Wireless N has become the standard at electronics retailers, promising faster connectivity with your wireless devices, faster transfer and streaming speeds between devices, and better connectivity. So what's to be done with your home's first wireless router?
Our suggestion is to install 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.
We've previously run down how to install DD-WRT on a Linksys router to give it many, many more features, including the repeater function we'll cover here. If you've already installed DD-WRT, then, skip to the section on repeater configuration. One notable difference in this guide, too, is that I'm installing a custom build of DD-WRT, the "micro" flavor, on a Linksys WRT54G ver. 6, or "version 6." Adam wrote his original guide in 2006, with a fully-DD-WRT-compatible Linksys WRT54GL router, and at that point, those who picked up a blue Linksys box without knowing about open-source firmware were pretty much stuck. Now there's a huge array of supported devices, and even my sadly restricted Linksys can run a Micro build, and Micro now includes a repeater function.
