Cascade Router

Hi,

I want to separate networks in my house and currently have a linksys router as the primary and is the one connected to the modem and would like to have this R8000P as the secundary. I am guesing the method to use to separate networks would be a LAN-WAN topology, can anyone verify this and what will be the settings that I need to change on the secundary router?.

 

 

Thanks

    Hi,

    Long story short:

    configuration used: LAN-WAN

    With Netgear (secondary router) default settings:

    1.-Changed SSID and password.

    2.-Connected Netgear's Internet yellow port to Linksys's (Primary router) LAN port.

    This way there was a conflict because both routers had the same LAN IP segment but the 

    Netgear Router changed its LAN IP to 10.0.0.1 automatically (but had to powercycle the unit) and 10.0.0.2 as the starting IP address.

    3.- Powercycle Netgear router

    The Linksys (Primary) asigned a 192.168.1.x to the Netgear internet IP address.

    The Linksys as I mentioned before is the one connected to the modem (outside world).

    The goal was to keep two separate LAN's with different SSID's and passwords and with the steps followed above I was able to achieve the goal.

     

    I also tried changing the Netgear's (Secundary) LAN IP segment to 192.168.2.1 and also works. Note that this change in the IP address was done before making the physical connection LAN-WAN.

     

    I hope this help.

  • When you say seperate are you talking completely seperate as one had nothing to do with the other? 

    Also how are you connecting to the internet?

      Good questions.

       

      The Internet one is important. If you want both networks to connect to the same Internet service, and to use the same modem, you'll have to be careful to avoid the two networks fighting each other to control things.

        I want to prevent the devices conected to the netgear R8000P (secundary) commuicate with the devices connected to the Linksys (Primary). A couple of examples are: I dont want to cast to the other tenant's chromecast or I dont want the other tenant send prints to my wireless printer all these by mistake.

        We need both routers have internet access but there is only one ethernet port on the modem plus the ISP provider only provides one IP.

        The primary router (Linksys) connects to the modem.

         

        Here is some information I found in Linksys's website:

       Why?  Is there some actual problem which you are trying to solve?  It
    might help if you started at the beginning, and explained what you're
    actually trying to do, rather than asking how to implement some
    particular "solution" to whatever problem you think that you have.

    > [...] I am guesing the method to use to separate networks would be a
    > LAN-WAN topology, [...]

       What, exactly, does "a LAN-WAN topology" mean to you?  (Inventing
    your own technical terms can produce more confusion than clarity.)

    > [...] can anyone verify this and what will be the settings that I need
    to change on the secundary router?.

       That all depends on what you want to do, and how.  Bear in mind that
    cascading routers can cause problems ("double NAT") for devices
    connected to the inner router.  Configuring the second router as a
    wireless access point can provide one unified LAN with no such problems.
