    Hey Tech Support Guy.

    Until recently, we only had a single wireless router for internet which worked fine downstairs, but we grew tired of not having internet on the first floor, so my father bought a second wireless router to be placed there, acting as switch only, thereby expanding the roaming area.

    I found some online guides for the procedure and did everything as told:

    Straight through cable between the routers, two random ports (NOT WAN).

    Main router - connected to WAN: Nothing changed.

    Secondary router: New IP (main router is xxx.xxx.xxx.1, and secondary is xxx.xxx.xxx.2), DHCP disabled.

    I have no problem finding both wi-fi networks, but I can only receive an IP through the main network. The second keeps trying to address me an IP, but with no luck...

    I tried unplugging everything and shutting power off, but with no result.

    The routers are two cheap *** brands that I am almost sure you do not know; Zolid Wireless-G (main) and ExtremeIT Wireless-G (secondary). The internal software is something called SOHO Router (main) and some unknown software for the secondary.

    It drives me crazy, please see if you can help...

    Your problem may be "Straight through cable between the routers."

    JohnWill's procedure (Aug. 30, 2008) for configuring a secondary router as a switch and, optionally, wireless access point follows.

    Connecting two (or more) SOHO broadband routers together.

    Note: The "primary" router can be an actual router, a software gateway like Microsoft Internet Connection Sharing, or a server connection that has the capability to supply more than one IP address using DHCP server capability. No changes are made to the primary "router" configuration.

    Configure the IP address of the secondary router(s) to be in the same subnet as the primary router, but out of the range of the DHCP server in the primary router. For instance DHCP server addresses 192.168.0.2 through 192.168.0.100, I'd assign the secondary router 192.168.0.254 as it's IP address, 192.168.0.253 for another router, etc.

    Note: Do this first, as you will have to reboot the computer to connect to the router again for the remaining changes.

    Disable the DHCP server in the secondary router.

    Setup the wireless section just the way you would if it was the primary router, channels, encryption, etc.

    Connect from the primary router's LAN port to one of the LAN ports on the secondary router. If there is no uplink port and neither of the routers have auto-sensing ports, use a cross-over cable. [You will not need a cross-over cable if one of the "routers" is a computer.] Leave the WAN port unconnected!

    This procedure bypasses the routing function (NAT layer) and configures the router as a switch (or wireless access point for wireless routers).

    For reference, here's a link to a Typical example config using a Netgear router

    Switching to a crossed cable solved the issue.

    Thanks a lot!
