I currently own a Linksys Wireless-B Broadband Router with two computers linked to it. One is connected through the Ethernet port, and the other is connected through a wireless connection. For two years, the router has only served as an Internet splitter. However, I am interested in setting up a network. I have spent hours searching the Internet, and I cannot find any information about setting up mixed (wireless and wired) networks.

Any help would be appreciated,
Thanks.
