Connecting modem to normal port not WAN port

I just replaced my linksys router with a n900. 

 

I have two office computers directly connected to the cable modem.  The cable modem was then connected to any open LAN port on the router.  A computer was then connected to another LAN port.  It was then was able to be on the same network and access the internet. .  

 

With the n900, if I connect the cable modem to a LAN port, the router indicates that there is no internet access. 

 

It it is my understanding that this is the only way to network computers connected to the router with computers connected to modem. 

 

What at am I missing!

 

thanks.

  • It sounds like your cable modem has a built-in router.  If true, then you should set up your N900 as an Access Point.  There are two ways to do this.

     

    1. If your model has an AP Mode setting, then enable it. You would then connect the N900's WAN port to one of the cable modem's LAN port.
    2. If your model does not have an AP Mode setting, then disable the DHCP server, set the LAN port to use an IP address in the same subnet as the cable modem but not an address that could be allocated by the cable modem's DHCP server (or else you run the risk of an address conflict) and connect the N900's LAN port to one of the cable modem's LAN port.

      i didn't have to change any settings.  I wasn't patient enough.  I unplugged the router, moved the modem connection from wan port to LAN port 4 and plugged it back in.  

       

      All is fine. 

       

      Thanks.
