connecting two routers

By gandalft

  1. Hi,
    I have 2 routers a netgear TA612V which has my modem connected to it and my phone (am using VOIP) I then have a Linksys wireless 54 G router connected which allows me to access the web wirelessly. This was set up by a housemate who has since left..

    Here is my problem. I need to get the IP address of the second router (Wireless 54G) Does anyone know how can I do this.

    inspect the connections carefully;

    Code:
    modem--(wan)TA612V (lan)----(xxx)Linksys-54-G(lan)---your systems
    the wire FROM the TA612V to the Linksys: which port(xxx) is it connected too?
    the Linksys WAN or one of the LAN ports?

    If it's a LAN port, then the Linksys has no IP address, is not acting like a router,
    but is a pass-thru connection to the TA612v which is providing the DHCP service
    AND which is your gateway address.

    you find the gateway address on any system:
    run->cmd /k ipconfig /all​

    It will be shown as the gateway

    It is connected to a LAN port. I found that by temporarily assigning a static ip address (192.168.1.5) to my pc I can then access the Linksys router (192.168.1.1)

    The reason I am trying to do all this is to secure my lan and enable WEP security on my wireless network (as I can see no way of doing it on the TA612V )

    Looks good -- are you good to go or still have issues?

    huh? when I
    run->cmd /k ipconfig /all​

    I get the IP address and all I thought should go with it but no gateway, are u refering to the gateway as IP?

    I take it the netgear is an adsl modem router and the linksys is a wtr54g or similar, cable modem router?
    Can you not just turn off all routing on the netgear and just setup the linksys to do it all?

    I am still having a probem -
    I enabled WEP security on the Linksys but when I do so I cannot connect wirelessly to the web. I get a "limited or no connectivitity" status on my wireless connection. I am wondering if this is because I am using the Netgear as the router.

    I might try k.jacko suggestion

    It depends. Where is your wireless pc getting its IP from, the netgear or the linksys?
    To answer your earlier question the gateway should have an ip. It will likely be the same ip address as the netgear router.
    Make sure only one router is handing out IP addresses, ie has DHCP enabled.
    In fact why not manually assign all your devices?
    I'd be sorely tempted to disable the routing on the netgear and just use it as a modem, and configure the linksys as your full router.
    By the way, unless you're using old wireless cards, don't use WEP, use WPA security.

    ipconfig /all results:

    The netgear will always act as a router, but with only one device (the linksys)
    attached, it doesn't matter. You do need to DISABLE the DHCP in the netgear
    (so cable netgear--system, access the config, and disable dhcp)

    Then recable the linksys [using one of the LAN ports]. Now access that config
    and DISABLE encryption altogether (just temporarily). You should have
    access to the internet (try ping www.google.com).

    Once you have routing to the ISP, you can go back and add WEP as a first step.
    WPA would be better, but sometimes that is not compatible
