Features Backward compatible with IEEE 802.11g, & 802.11b Wi Fi networks Supports WEP, WPA & WPA2 wireless authentication Built-in firewall with IP, MAC Address & URL filtering Built-in configuration utility (web-based) Dual internal 2d Bi antennas The WFREPEAT300N Wireless-N Extender offers two selectable operating modes that enable it to be used as an Access Point or repeater, for either extending the range of existing wireless networks or adding wireless capabilities to a non-wireless network. Using a wall plug design, this allows for convenient or hidden placement anywhere there is an available AC outlet. Used as a Wireless-N repeater, the WFREPEAT300N can expand the effective range of any 802.11n Wi Fi network, delivering up to 300 Mbps of data bandwidth, by boosting the Wi Fi signal to help eliminate dead spots & provide a stronger signal in areas with obstructions which would typically reduce the wireless range. The Wi Fi range extender is also backward compatible with 802.11b/802.11g networks, for versatile network expansion with wireless routers that use older standards. When used as a wireless access point (AP), the WFREPEAT300N can add wireless-N capability to any non-wireless router, ensuring maximum convenience & network scalability. To provide maximum privacy & help prevent network intrusions, the Wireless-N Extender/ Repeater offers a built-in firewall with IP, MAC Address & URL filtering, & supports common Wi Fi security protocols (WEP/WPA/WPA2).
