By following that guide, you will obtain the essential information and setup instructions for the extender. Gather the extender’s login information and other credentials while you’re at it, as you’ll need them for the setup. However, there are a few more requirements that must be met for the setup procedure to be finished. For example, the SSID network name and password you use to configure your current router. Beyond that, a device—your laptop, smartphone, or PC—will be required for carrying out the process. Here, attaching an Ethernet line is optional.
