Introduction At up to five times the speed of previous wireless devices, you can work faster and more efficiently, increasing productivity. With the DI-774, bandwidth-intensive applications like graphics or multimedia will benefit significantly because large files are able to move across the network quickly. This versatile wireless router also features four times the number of non-overlapping channels than a device that supports only 802.11g, so more users can access the network.
Connections - Back Panel of Unit All Ethernet Ports (WAN and LAN) are auto MDI/MDIX, meaning you can use either a straight-through or a crossover Ethernet cable. Pressing the Reset Button restores the router to its original factory default settings. Auto MDI/MDIX LAN ports automatically sense the cable type when connecting to Ethernet-enabled computers.
Features ! Fully compatible with the 802.11g standard to provide a wireless data rate of up to 54Mbps ! Backwards compatible with the 802.
LEDs - Front Panel of Unit LED stands for Light-Emitting Diode. The DI-774 has the following LEDs: Power A solid light indicates a proper connection to the power supply WAN LED A solid light indicates connection on the WAN port. This LED blinks during data transmission Status A blinking light indicates that the DI-774 is ready WLAN LEDs for 11a and 11g wireless network segments. A solid light indicates that the wireless segment is ready.
Wireless Basics D-Link wireless products are based on industry standards to provide easy-to-use and compatible high-speed wireless connectivity within your home, business or public access wireless networks. D-Link wireless products will allow you access to the data you want, when and where you want it. You will be able to enjoy the freedom that wireless networking brings. A WLAN is a cellular computer network that transmits and receives data with radio signals instead of wires.
Wireless Basics (continued) Standards-Based Technology The DI-774 Wireless Broadband Router utilizes the new 802.11g standard, in addition to the 802.11a and 802.11b standards. The IEEE 802.11g standard is an extension of the 802.11b standard. It increases the data rate up to 54 Mbps within the 2.4GHz band, utilizing OFDM technology.
Getting Started Setting up a Wireless Infrastructure Network 1 2 3 4 6 5 For a typical wireless setup at home (as shown above), please do the following: You will need broadband Internet access (a Cable or DSL-subscriber line into your home or office) Consult with your Cable or DSL provider for proper installation of the modem Connect the Cable or DSL modem to the DI-774 Wireless Router (see the printed Quick Installation Guide included with your router.

WEP- Select Enabled or Disabled. Disabled is the default setting.
Using the Configuration Menu (continued) Home > WAN > Dynamic IP Address Dynamic IP Address- Most Cable modem users will select this option to obtain an IP Address automatically from their ISP (Internet Service Provider). Host Name- This is optional, but may be required by some ISPs. The host name is the device name of the Router. MAC Address- The default MAC Address is set to the WAN’s physical interface MAC address on the Router.
Using the Configuration Menu (continued) Home > WAN > Static IP Address Static IP Address- Select this option to set static IP information provided to you by your ISP. IP Address- Input the IP Address provided by your ISP Subnet Mask- Input your Subnet mask. (All devices in the network must have the same subnet mask.) ISP Gateway Address- Input the Gateway address Primary/ Secondary DNS- Enter a DNS Address if you do not wish to use the one provided by your ISP.
Using the Configuration Menu (continued) Home > WAN > PPPoE Please be sure to remove any existing PPPoE client software installed on your computers. PPPoE- Choose this option if your ISP uses PPPoE. (Most DSL users will select this option). Dynamic PPPoE- receive an IP Address automaticsally from your ISP. Static PPPoE- you have an assigned (static) IP Address.
