Faster Wireless Networking SNMP Management Better Security with 802.1X and WPA Five Different Operating Modes Access Point Point-to-Point Bridging Point-to-Point Multipoint Bridging Wireless Client Repeater 108Mbps 1 Wireless Networking Able to achieve a maximum wireless signal rate <strong>of</strong> up to 108Mbps 1 , increased speeds means increased productivity. With <strong>the</strong> DWL-2100AP in your home or business, colleagues, friends, or family can communicate with one ano<strong>the</strong>r in real-time to download large files or to smoothly stream MPEG videos. The DWL-2100AP Wireless Access Point gives you <strong>the</strong> freedom <strong>of</strong> wireless networking at D-Link 108G speeds that save you time, money, and make your wireless networking experience more enjoyable. The DWL-2100AP is not only fast but it also supports SNMP v.3 for better network management. A Wireless AP Manager s<strong>of</strong>tware is available with <strong>the</strong> DWL-2100AP for network confi guration and fi rmware upgrades via a web-based confi guration utility. For Enterprise networks, <strong>the</strong> DWL-2100AP supports network administration and real-time network traffi c monitoring via D-Link’s D-View Network Management s<strong>of</strong>tware. With <strong>the</strong> DWL-2100AP, wireless clients can securely connect to <strong>the</strong> network using WPA (Wi-Fi Protected Access) and 802.1X au<strong>the</strong>ntication providing a much higher level <strong>of</strong> security for your data communication. AES (Advanced Encryption Standard) is also supported by <strong>the</strong> DWL-2100AP to maximize <strong>the</strong> network security with data encryption. The DWL-2100AP can operate in one <strong>of</strong> fi ve different operational modes featuring WDS (Wireless Distribution System) to meet your wireless networking requirements: Create a wireless local area network. Wirelessly connect two networks. This mode provides a cost-effective solution when traditional wired solutions are too costly or prohibitive. Wirelessly connect multi-networks. This mode acts as a hub to connect multiple wireless networks. Wirelessly connect E<strong>the</strong>rnet devices. Provides immediate connection for E<strong>the</strong>rnet devices without <strong>the</strong> need for any drivers. Repeats radio frequency to extend <strong>the</strong> 2.4GHz range for your wireless LAN.
