Before You Begin
1. If you purchased this router to share your high-speed Internet connection with other
computers, you must have either an Ethernet-based Cable or DSL modem with an
established Internet account from an Internet Service Provider (ISP).
2. It’s best to use the same computer that is connected to your modem for configuring
the DI-774 Tri-Mode Dualband Wireless Router. The DI-774 acts as a DHCP server
and will assign all the necessary IP address information on your network. See
Appendix at the end of this Quick Installation Guide or the Manual on the CD-
ROM for setting each network adapter to automatically obtain an IP address.
