Features, Benefits & Specifications
Shared Internet Access for Wireless and Wired Users
The 3Com® ADSL Wireless 11g Firewall Router combines an ADSL2/2+
modem, router, 802.11g wireless access point, four-port switch,
and firewall to enable up to 253 total (64 wireless) users to
economically and securely share a single ADSL or ADSL2/2+
connection. The high-speed routing engine easily handles large
data transfers and Internet downloads, including those from
multimedia applications.
The 11g ADSL router provides a high-speed, 54 Mbps wireless
connection for users with 802.11g-equipped PCs and laptops. It
is also backward-compatible with 802.11b wireless LAN equipment,
preserving existing network investments. This Wi-Fi certified
router also features support of Wireless Distribution System (WDS).
WDS simplifies setup of an extended or completely wireless
network (requires access points that support WDS)
Advanced wireless security and multiple firewall features offer
one of the industrys strongest levels of protection for the
network. To shield wireless connections, the 11g gateway router
implements 256-bit WPA encryption for maximum security, along
with 40/64- & 128-bit WEP encryption for legacy clients.
Stateful packet inspection firewall, hacker pattern detection,
URL filtering, and other security features help protect the
entire network from attacks and other Internet security risks.
The unit comes with a 14 day free trial of the 3Com®
OfficeConnect® Content Filter Service, a premium subscription
service for OfficeConnect routers that blocks access to
pornographic, prejudicial, violent and undesired Internet web
content or services.
NOTE: This product is designed to support DSL over POTS (ITU
Annex A). Availability varies by region; check with your ISP for
