    I'm trying to replace two wireless routers in a home wireless network set up. The network consists of:

    One Belkin router going into a Cable Modem (Time Warner). In the LAN ports of this router there are two connections that represent data ports upstairs. I can't get into the config sheet of this router.

    The second Belkin router is in the lady's study and it is hard-wired to its WAN port. I can get into the config page and it is 192.168.2.1 and it has DHCP on, although curiously, when I wirelessly connect to it and right click the wireless network connection, in the properties sheet it shows as access point.

    The third Belkin router is in a bedroom at the opposite end of the house and it wasn't hard wired and I can't get into its config sheet. My guess is that it must have been hard wired into the data port on the wall as these routers can not act as wireless repeaters.

    When I swap numbers 2 and 3 out neither of the two new ones can connect to the Internet which makes me think that router 1 is mac address controlled or the cable modem is blocking Internet access?

    I'm at the point where I think I am going to have to break everything and start from scratch but I am hesitant without knowing how the existing network was set up as ideally I just want to mimic it but with fresh hardware. On the new routers, when I connect to the interface I can set up all the security etc. but the only thing that is missing is internet connectivity.

    Cyber pint to anyone that can shed any light on what I should do next. :D

    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. 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

    Thanks. I was trying to avoid re-configuring the whole network but it looks like it is the only way out of it.

    If you're using DHCP for all the computers, the "reconfiguration" of the computers is simply turning them all off, then starting them up one at a time.
