For the LAN interface, there is a built-in 4-port, full-duplex 10/100 Ethernet switch that can connect up to four devices. The wireless AP supports 802.11b/g & incorporates Linksys Range Booster technology, which utilizes a MIMO antennae configuration to provide increased coverage & reliability over standard 802.11g. The WRV210 has the advanced security functions needed for business networking. It has a stateful packet inspection (SPI) based firewall with Dos prevention, but also a Virtual Private Networking (VPN) engine. VPN enables secure communications over the Internet between your office & mobile, remote workers or branch offices. For your wired & wireless local area network, there is support for multiple SSIDs & VLANs for traffic separation. The WRV210s Wireless AP implements WPA2-PSK, WPA2-ENT, & WEP encryption, along with other security features including enabling/disabling SSID Broadcasts & MAC-based filtering. Wireless networking in business environments requires additional flexibility. The WRV210 has the capability to expand or reduce the area of your wireless network. There is support for Wireless Distribution System (WDS), which allows the wireless coverage to be expanded without wires through wireless bridging between it & select Linksys stand alone access points. That, along with the ability to increase or decrease the RF output power, allows for optimal wireless coverage. Qo S functionality can improve the quality of your voice or video over IP. With support for Wireless Qo S (WMM) & wired Qo S (port prioritization), consistent voice & video quality is maintained throughout your business. Please note: networking components such as switches, routers & wireless devices require that speeds & standards be consistent throughout the network to gain optimum performance.
