This project was installed about a year and a half ago and has been functioning since. There have been times I needed to reboot the repeater throughout the year, so it’s not like you can install it forget about it (unless you buy commercial products, not a Linksys). You also have to keep an eye out for growing shrubs and trees, since that will limit your signal over time.
First up, you’re going to have to have access to an internet connection (DSL/Cable). I had the luxury of having my parents near by, so I didn’t have to deal with any neighbors trying to secure an internet connection during construction (check your area and see if anyone has their wireless wide open… you might just want to repeat that signal).
