is it better to buy just a router or a modem/router combo

The modem for the phone is a separate piece.  You'll still need a modem/router for the Internet. 

I recommend a combo for the sake of cables & cluttter.

we have had a netgeR combo I purchased at a cox store ( so they have to stand by it) for less than what it would cost to purchase individually at Best Buy. 

They keep warning me that that's " my problem," but that's only because it's over 3 years old. 

It's NOT my problem. There are soooo many problems. 

Welcome to ***.

I always recommend a separate internet modem and a WiFi router. That eliminates a single point of failure with a combination unit. 

Thank you guys for the quick answers. I know if I got just a router, then I would have to connect it to their provided modem via Ethernet port. what about if I purchased the modem/router combo, does it have to be connected to their modem also, or I can connect it to another coaxial outlet in the house?

boqal57,

If you are interested in purchasing a modem/router combo, you can use that as a stand alone device for your internet service. At this point, the modem/router would need to be connected to another outlet in your home.

MarkM1 thanks that helped gives me a picture of how I plan my set up.
