    How do I properly setup a Linksys wifi router to work behind a network.

    what ive done so far:

    1. Turned off DHCP on the wifi, since my network already has DHCP
    2. Turned off NAT service on the wifi
    3. Turned DHCP configuration on the wifi so that the existing network will asign IP

    I can connect to WIFI but cannot get internet. At first I was able to, aftter turning it off and turning it back ON, I cant get internet. Is my configuration correct?

    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. Note that you should use the same SSID and encryption key for the secondary router but a non-conflicting channel. I recommend channels 1, 6, or 11 for use for the best results.

    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. 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
