The WiFi extender uses brand-new software technology, simple to set up and easy to use. Universal compatibility and easy setup: This WiFi extender can be used with any 802.11b/g/n/a wireless internet router, which means it can be used with any standard router or gateway. WISP mode/AP mode, most home users will set it up in one of two ways: 2. Range extender (it connects to your existing wireless network wirelessly and enhances/extends the signal) or 3. Access Point (it connects to the Internet or your existing network via Ethernet and then broadcasts the wireless signal (this is how you use it). Easy to set up: You can use PC/smartphone/laptop to set up. (Smartphone settings are simpler), connect to WiFi, enter the password to complete the setting. If you have a dead wireless zone in a corner of your house. Please do not place it directly in a blind spot (because it cannot receive the existing signal to expand it out). Please be sure to play in different places to place it, and you will find a great location. I put it in a location with some wifi signals, set everything up, and then walked to the quot,dead zone quot.
