802.11g 2.4GHz Wireless Router
With 4 Port 10/100 Switch

DESCRIPTION

The ARM904 is an IEEE 802.11g compliant wireless router with a

built in four-port fast Ethernet switch. It brings the latest wireless

technology with high speeds up to 54Mbps, which is almost five times faster than the 802.11b wireless

network. This high transfer rate provides relief from the pain of waiting while you are downloading large files,

web surfing, having a video-conference, playing stream high-quality digital movies, etc.

The ARM904 is interoperable with all other 802.11b wireless devices, so that you can use it with both your

already purchased 802.11b devices and newly 802.11g investments.

This high-performance IEEE 802.11g standard-based router allows you to connect all of your wireless

equipped PCs, while an integrated built-in 4-port fast Ethernet switch connects your devices that need

Ethernet wiring. It’s the easiest way to share and extend your high-speed xDSL/cable modem Internet

connection; either with or without wires.

The ARM904 provides not only the ease of Internet access, but also the privacy of data transmission.

Network Address Translation (NAT) provides your network with protection from intruders, while 64 and 128-

bit WEP (Wired Equivalent Privacy) encryption guard your wireless network for maximum privacy. Additional

security features include pass-through of multiple concurrent IPSec and PPTP VPN sessions for

telecommuters or for anyone who needs to transmit sensitive information more securely.
