Can I use my CM500V-100NAS Modem with the Wired-Only Internet Router you sell for a wired no WI-FI connection

Can I use my Netgear CM500V-100NAS Modem with the Wired-Only Internet Router you sell, for a wired no WI-FI connection. Also why does it need to be grounded?

Under review

Yes, absolutely!  It is plug-and-play when you receive it from us.  Just disconnect the power from your cable modem before hooking it up, that way your cable modem (some modems and providers are more clumbsy with this) is sure to recognize the new router, and it will work great for you!

Is it true that there can be an issue if my modem does not split the IP addresses. How do I know if the Netgear CM500V-100NAS Modem does?

Thanks So much

I tried to use my Netgear Router which supported voice with a trendnet 4 port Ethernet broadband router, this didn't work because there was no way to connect my cable cord that comes out of the wall, slits into two. one was into my Netgear modem and one into comcast router but when I switched this to a Trendnet router I had no place for the cable in it.

Looking at your low wifi routers, I don't see a place there either for cable. 


1.How do I hook up the cable box when using these?

2. They don't support voice, correct?


A true cable modem will have just 1 or 2 Ethernet ports on them.  Most have 1.  This port connects to the WAN/Internet port on your router.  If a cable modem has 2, that means it supports trunking (advanced thing for super high speeds).

Modems don't handle IP addresses - your router retrieves an IP address through the modem.  This all happens automatically.  If for some reason you had a problem at first - power down the modem for 30 seconds.  Leave the router ON.  Then power the modem back up.  The router should fetch itself an IP address for the Internet (Public IP address) through the cable modem.

The modem you have supports voice.  Routers won't have anything to do with that part.

You say Netgear Router - but is it actually a cable modem?  Does it have a screw-type cable TV connector on it?  If so - it's not a router, but instead either a modem or a modem/router combo.  You would not be able to use this with another modem.

You say your cable cord that comes out of the wall.  You mean the router coaxial cable TV cord?  It sounds like you have 2 cable modems.  Only one of them is probably active.  You need to use that one.  Or you need to call Comcast and have them activate the one you want to use.  Then, that modem should hook into our router.  The CM500V modem is the one you want to use.  That's just a plain modem, not a router.  Then you would use our router with it.  It will work very nicely and be the ideal setup.

Your cable TV box for watching cable TV just hooks into a coaxial cable wire.

You are correct the Newgeat CM500 is my Modem, sorry. I attached that to the TRENDnet 4-Port Broadband Router TW100-S4W1CA. But it didn't work because only the modem has the place for the Coaxial cable to attach. 

For the last year it has been cable coming out of the wall, split into both the CM500 Modem and the Comact cable box which don't think I can use with the Trendnet box because no place to attach it. Comcast says must have cable box.

Any idea what I'm doing wrong:-)
