Hi, Do you want the computers in the shop to talk or transfer files with the first router?? I've done this with linksys (since I'm a new d-link owner). Set the shop router up with an IP, username and password. Write them down and access them several times (GP). Make sure the wireless network names are different. Turn off the DHCP on the router in the shop and let the 1st router assign IPs. That can be done under Setup->Network Settings. Make sure you have enough addresses in the IP address range. The d-link routers seem to take awhile to boot or what ever they do, so give it some moments after you save settings. Hope that helps. Luke.
