The Linksys re1000 extender supports a CD setup that only requires inserting the CD and following some basic points. So, once you unbox the extender, take out the device and the setup CD as well. Make the extender ready for the setup by plugging it into a power socket and turning its switch on. Then, use your PC and insert the CD into the ROM to start the Linksys re1000 setup. Once the setup window appears on the PC screen, click on the option and let the PC perform the process. Follow the setup directions as displayed and finish the setup in this way.
