Need suggestion in modem, etc

[Ironjim]

I currently have an 8 year old modem and router. Have Comcast Internet, couple I pads and I phones, laptop, Apple TV. etc.
Getting ready to upgrade to xfinity. They tell me I need a new wireless gateway. Excuse my ignorance but do I still need a modem and router or is it just one device now? Any suggestions on what to purchase ?

Comcast has devices that are a modem, router, and wireless access point all in one box. I would suggest not getting one of those and instead opting for the modem only box, then using a wireless router of your choice.

here in california, the advantage of renting comcasts modem deal is it has a battery backup.

the disadvantage is that a cable modem only costs $89 and comcast wants you to pay what.. $10 a month now to rent theirs

if you get the comcast modem and wifi router , they will turn your house to a free wifi hotspot and you have to opt out.

I'm always for the buy your own modem and buy your own router (I always prefer to have the modem and router/wireless separate from each other).

I've been using my same Motorola SB6120 for 4+ years now. Rental fees would be at least $400 by now.

Plus the wireless range and features on the Comcast all-in-ones they give out are not really that great.
