My name is Martha French, working as a technical and extenders support expert in CA. A few important components are needed for the Linksys extender re6700 setup. This would first be a compatible Wi-Fi router, preferably with WPS to make it easier to connect. It expands the existing network, so a working router is a must. A device with a web browser is needed to access the setup interface of the extender. Connect it to the initial Wi-Fi network of the extender, with a name that is usually found on the label of the extender. You should have your router placed where it can output a sufficiently strong Wi-Fi signal for full performance. The extender only bridges signals; otherwise, a weak initial signal would limit the range of the RE6700. Finally, have the right power adapter for your RE6700 along with an appropriate electrical outlet. While no special software is technically required, new firmware in your router does improve compatibility.
