Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do what I can to provide the right answer to your question. You need to hook up a computer with an Ethernet cable to one of the common, numbered, ports on the DLink router. Enter the DLink router's default IP address
, in a web browser on that computer. (It might be 192.168.0.1, or 192.168.1.1, perhaps.) You'll get a prompt for username and password ***** enteradminfor the username, and one of several choices for the (default) password ***** it might be just a blank password (no characters), or it might beadminor it might bepassword(which may sound inane, but those are commonly used default router passwords, as they are sold, or as they are reset back to default settings by having their RESET buttons held down for 1/2 minute or longer continuously.) Once you have logged in, you will be able to find the setting for Bridge mode, rather than for (Router mode or) Gateway mode.(You might also want to set the DLink's IP address to one that would make it belong to a subset of the Linksys WRT54G2 router's own IP Address... e.g. if the Linksys router's IP address were 192.168.1.1, and if the Linksys router assigns IP addresses starting with 192.168.1.2, then you might want the DLink router's own IP to be 192.168.1.100, and have it assign IP addresses starting with 192.168.1.101. But that's up to you, and these are just examples. The two things you really *have* to do are, not have any duplicate IP addresses on the whole local network, and allow enough local address space for each router/box/etc. to assign addresses to connected devices, freely, without causing duplicate IP addresses.) Save the changed settings, then disconnect the computer from the DLink router, then hook up the DLink router in its place.
