Introduction

D-Link announces a fast, mobile network router which allows you to share a high speed Internet connection virtually

anywhere by connecting an UMTS or HSDPA notebook adapter or USB-enable phone. You can get a high speed Internet

connection just about anywhere within your wireless broadband network. This router is extremely useful in situations

where a wired broadband connection is not available. Quickly set up a Wi-Fi hotspot and provide your workgroup with

an Internet connection to check email and browse the web or share file. Maximize your investment in your mobile

Internet access subscription by using this router as a fixed broadband Internet solution for the home instead of paying

additional fees for cable or DSL.

ADVANCED.NETWORK.SECURITY

The 3G Mobile Router creates a secure Wi-Fi

®

network by supporting the latest wireless security features to prevent

unauthorized access. Support for WEP, WPA, and WPA2 ensure that you will be able to secure your Wi-Fi network,

regardless of your client devices. In addition, the 3G Mobile Router utilizes dual active firewalls (SPI and NAT) to prevent

potential attacks from across the Internet.

EASY.TO.INSTALL.AND.USE

The D-Link 3G Mobile Router sets up in minutes, making it easy to use while on–the-go. Remaining backward compatible

with 802.11b devices, this router ensures that it will work with legacy wireless equipment you already own. This eliminates

the necessity of incurring additional expenses with upgrading your current wireless equipment. You can also directly

connect Ethernet-based devices to its built-in 4-port full-duplex 10/100 switch.

Set up a wireless network with the D-Link 3G Mobile Router DIR-451 and provide your users with a secure, high-speed

connection to the Internet anytime, anywhere*.

* Requires third party mobile Internet access subscription. Check with your service provider for service coverage and applicable

fees. D-Link does not guarantee compatibility with all UMTS or HSDPA wireless networks or third party Internet PC cards.
