I have a Linksys wireless router (WRT54G Ver. 2). I just moved into a condo with an existing network setup. The network is configured as follows: Coax Cable to Cable Modem--> D-link Switch---> wired ethernet ports throughout the condo. The IP address out of the modem is 10.48.92.82. I found this out by connecting my laptop directly to the modem via an ethernet cable. the IP address coming out of each port on the D-link switch is also 10.48.92.82. The default IP address on the Linksys wireless router is 192.168.1.1. If I connect an ethernet cable from the wall to the wireless routers internet port and then to my computer from one of the numbered ports on the wireless router, I can access the internet through the direct cable connection (Local area network) but not wirelessly. I have also tried the following: set the IP adress on the linksys wireless router to 10.48.92.90 and disabled dhcp. I then connected a cable from the ethernet port in the wall to one of the numbered uplink ports on the back of the linksys wireless router. Then, connected to the wireless network with my wireless laptop and still no internet. I have been working at this for 2 days and still no luck. Could someone please help???

the dlink router should be between the modem and the switch. If the switch doesn't have a uplink port or support mdi/mdix you will need a crossover cable to go from router to switch.

How do i need to configure the wireless router? What IP adrdees do i use and how do I wire it.

Download the routers manual and review it. It will tell you everything you need to know step by step. I have already diagrammed the wiring for you above.
