CM700 Cable Modem Support for two routers
I have a Netgear CM700 Cable Modem and have had it for about 6 months connected to a router. It works fine. I wanted to add a second router so I installed a Netgear Prosafe switch between the original router and the cable modem. That works fine. However I can't figure out how to add a second router to the switch. All i get from a browser when connecting to the second router is No Internet Connection. I did have the second router connected to the first router and that worked fine. However the cabling in my house requires me to use the switch. Any ideas?

The CM700 and most cable modems only service 1 WAN IP address.
Standard networking connect configurations for home class modems and routers and switches are:
Cable modem>Router>Switch<All wired devices to switch.
You can't have two routers behind this model modem.
If your ISP supports having more then 1 WAN IP address, then you would need a CM1100 or 1200 modem. Those support more than one IP address coming from the WAN/ISP.
