Extend Wi-Fi coverage to dead zones which your existing Wi-Fi signal can't reach. Plug the extender directly into an electrical outlet and double the signal coverage of your Wi-Fi network for better Wi-Fi quality across different rooms or multiple floors in your home.
Featuring iQ Setup
Featuring user-friendly browser-based iQ Setup, the EW-7438AC allows for smart, automatic and quick installation. iQ Setup automatically detects the available Wi-Fi networks nearby and helps you establish a connection in a few seconds. The EW-7438AC can work as Wi-Fi extender, access point or Wi-Fi
bridge. Just configure the mode you need for your network environment using the smart iQ Setup wizard and enjoy surfing the web. The extender works together with the free EdiRange smartphone app which displays your local Wi-Fi environment and provides easy-to-understand analytics. Plus you can manage the extender's wireless network and functions such as scheduling and guest network.
Conserve Power With One Click
Universal compatibility and easy web-based iQ Setup for quick and easy installation. Featuring a new hardware switch to adjust between normal and green Wi-Fi transmit power (the strength of the Wi-Fi signal) or switch off the power with one click. If you only need Wi-Fi in a smaller house, you can switch to green mode to reduce transmit power by 75% and conserve energy.
Cross Band Technology for Maximum Speed
Edimax cross-band technology uses both frequency bands together to maintain your router's maximum speed capacity through your extender and to your Wi-Fi device. Data is transmitted on one band and received on the other band, meaning no speed loss at your extender and a faster network with better performance. Perfect for high-speed applications such as HD video streaming or online gaming. Designed with a signal strength LED which lets you see the Wi-Fi signal strength received from the router1 and guides you to find the best setup location.
Easily Set Up Wi-Fi Access Schedules
Program intelligent schedules to manage Wi-Fi availability and power usage according to your home's routine. The EW-7438AC also features a guest wireless network which could be used for visitors only and help to keep your home Wi-Fi private and secure.
