2. Connect a computer or a mobile device to the range extender's default WiFi name, which is Linksys Extender Setup – xxx.

NOTE:  The xxx represents the last three characters of your range extender's MAC address which is located on the label at the back of the device.

3. Open a web browser and enter "192.168.1.1", "http://extender.linksys.com" or "http://RE7350-xxx" (the xxx represents the last three characters of the range extender’s MAC address). Then click or tap the Manual Setup link on the range extender's setup page.
