Router won't let second router/switch access internet?

I have a Netgear WNDR3400v3 that is the primary router for my home LAN situated inbound from the modem. I also have a Linksys BEFSR81 V3 that I am trying to configure as just a switch downstream from the Netgear in order to extend my wired network a bit further in the house. I have disabled the DHCP on the Linksys and given it a static IP on the same network segment (IP is 192.1685.1.250,, Gateway is, DNS is with 2nd DNS is set at Googles With this setup I am able to see the now configured Linksys switch on the LAN but cannot access the Internet with any device hooked into the Linksys. I know I'm probably missing some configuration that is very simple but for the life of me I cannot find it. Please help.

Going by your query the main issue is about the configuration of Netgear WNDR3400v3 as your main router and Linksys BEFSR81 V3 as the switch or extension. Here I will discuss a detailed configuration of your main router Netgear WNDR3400v3 to your secondary router Linksys BEFSR81 V3. Follow the set of instructions given below very carefully:

1.Set your main router Netgear WNDR3400v3: Connect your Netgear WNDR3400v3 to your computer using an ethernet cable. Connect one end of the cable into the LAN port of your Netgear router and the other end goes into the computer's ethernet port. Wait for few minutes to let the connection get established between the two.

  • Open your web browser and enter your default IP address in the URL field and hit Enter. This will redirect to your router's web interface. Login to your router as admin.

  • Once on the page, go to your network settings or LAN settings and enable the DHCP for your Netgear router.

  • Once the settings are changed and DHCP is turned ON, check your internet connectivity by visiting a website.

  • Once the testing is complete and everything is working fine, disconnect the cable connection from your primary Netgear Router.

  1. Setup your secondary router Linksys BEFSR81 V3: Now plugin your Secondary Linksys BEFSR81 V3 router into your computer's ethernet port using an ethernet cable as mentioned in the previous step.

  • Now open your web browser and enter the default IP address of your secondary router in the URL field as above and hit Enter. This will redirect you to the web interface of your secondary router. Login to your router by entering the credentials required.

  • Once on the page, go to your DHCP settings in the "LAN settings" and disable the DHCP configuration so that the secondary router does not receive any automatic Ip address from the server.

  • Now assign a new IP address to this router. Go to LAN settings in your router and look for "Current IP address" and enter your current IP address with the same subnet as the main Netgear router i.e first 3 octets should be the same. for example, if your primary router has an IP address of then the secondary router should have an IP address of

  • Now configure the username and password of your secondary router same as your main or primary router.

  1. Complete your setup: Once the configuration of both Linksys and Netgear router is complete, set it up in your home. Connect your primary router to your secondary router using an ethernet cable. Plug your main router and secondary router to a power source and restart the whole setup. Now you should be able to use your secondary Linksys router as a switch.

If you are having difficulties accessing the Internet through your Netgear router then you have to modify settings in the router itself. Luckily, accessing the router settings does not rely on Internet access, but rather on a direct connection to the router. It is better to use an Ethernet cable in case you have to modify wireless settings.

1.Verifying that Internet connection is active - Connect the computer to the router using an Ethernet cable. After this proceed to next step.Some Cable modems have their USB ports configured by the ISP to give your computer the Internet connection. If the physical connection is through a USB port, you will not be able to go online using an Ethernet connection. To have the Ethernet port of the modem configured, contact your ISP.

2. Connecting devices together -Connect the Cable modem to the Netgear router’s Internet port.(as shown in figure)

Connect a computer to any of the router's numbered ports (1, 2, 3 or 4). Connect the power adapter of your router to the power outlet. After connecting the devices together, check the lights on the front panel of the router.  Ensure that the lights corresponding to the ports where the Ethernet cables are connected to are blinking or not.

3.Configuring router for Cable Internet connection -

  •  Access the Netgear router’s web-based setup page.  Open any web browser such as Internet Explorer and enter Netgear router’s IP address in the address bar then press [Enter].

  • You will then be asked for your login details.  Leave the Username field blank and enter “admin” in the Password field then click OK

  • If you have received an error message after typing your router’s password, this means that the password entered is incorrect.  Try accessing the router’s web-based setup page again and enter the correct password.

  • On the Setup tab, click MAC Address Clone.

  • Thus, for Netgear router to work with your ISP, you have to enable the MAC Address Clone feature.  This will allow your ISP to recognize the router as the computer with the registered MAC Address.

  • Select Enabled then click on Clone My PC’s MAC.

  • In last, just save settings.

Note: Once the MAC Address Clone feature is enabled, Internet status should be active. 

4.To check internet connection status -To check the Internet Connection status, firstly ensure that the Internet Connection Type is set to Automatic Configuration – DHCP. Now follow these steps-

  • Firstly, Click on the Status tab.

  • Check the Internet IP Address.  If it has numbers, this means the router has been properly configured.  If the Internet IP Address values are showing up, click on Release IP Address then the Renew IP Address buttons. For Wireless-B and Wireless-G routers, click on the DHCP Release and DHCP Renew buttons.

You should now be able to access the Internet. If not, then please revert back.
