In order to optimize the performance and security of the Linksys extender, accessing its basic settings is vital. First of all, access the Linksys extender login network. In most cases, this would be through Wi-Fi. Using your web browser, type the extender's IP address - a number like 192.168.1.1, found on the label of the device or its documentation. Log into the extender using the administrator username and password. From here, you'll be able to set up a few basic options. In this case, that includes setting a more memorable network name, or SSID, and setting a strong, secure Wi-Fi password through WPA2/WPA3 encryption or WPA3 encryption. It's also possible to update the firmware on your extender so that it is always current and has all of the latest features and security patches. If your extender supports dual-band, look for options to extend both your 2.4GHz and 5GHz networks.
