My company recently built a second building about 500 feet from our current facility and we had fiber optic cable run with media converters at each end to convert it back to CAT5e cable. We have a Linksys WRT54G in the first building which handles the DHCP distribution of IP addresses. The company purchased a CISCO 1811 wireless router and the president would like to have it setup in the new building to give us wireless connectivity in that building. My problem is that I am not sure how to configure it to work with our current network structure and not cause issues with IP routing. Any assistance would be appreciated. Need to know what to connect to and how to configure the router.
