High Speed 4-Port Wireless-N Router

High-Speed WIFI Network
AZTECH WL557RT4 is a High Speed 4-Port Wireless-N Router. It is a wireless area network (WLAN) access point (AP). Utilizing 802.11b/g/n wireless technology, the data transfer rate can reach up to 300Mbps. With the WL557RT4 at the center of home or small office network, you can share a high-speed Internet connection to streaming HD IPTV, transfer large files of music, photos and documents, and playing on-line games. It is integrated with 4 fast Ethernet LAN ports, which are able to work as a backup for the Ethernet enabled device. Those features make it ideal for home and small office use.

Reliable Coverage
WL557RT4 supports enhanced MIMO technology, which can effectively reduce the “dead spots” in the wireless area, and extend the range of wireless network coverage to 4 times farther than wireless-G devices.

Advanced Security
The device is featured with Wi-Fi Protected Access (WPA) and 64/128-bit WEP Encryption to secure the wireless network. It also supports advanced security features such as WPA2 and AES to keep your wireless connection safe from unauthorized access.
