I'm not a geek, so please reply in English, thanks! 
Things that may be relevant: My internet is Comcast. I have "Xfinity" ... that's all I know. I live in an 850 sq. ft. apt. I have a laptop, a potentially-wireless printer, and a smartphone; someday I will have a tablet.
I just got back from Best Buy. I had expected to leave with a router, but there were too many choices and even the sales dudes couldn't agree on what I need, so that's why I'm posting here.
I own the modem. It's a Motorola SB5101U. DOCSIS 2.0. One of the reasons I didn't buy the router this morning was because one of the sales dudes said my modem needs to be DOCSIS 3.0.
QUESTION #1: Does my modem NEED to be DOCSIS 3.0? Will my 2.0 modem work with whatever router I buy today? If not, why not? Can you tell me anything else about what DOCSIS is/means?
QUESTION #2: Salesdude #1 recommends the Netgear N600; he said it was a "good entry-level modem." That sounds like it may need to be upgraded sooner rather than later, so I'd just as soon buy something a little better now, if that's the case. I seem to recall someone warning me against buying Netgear anything. This one is about $80
QUESTION #3: Salesdude #2 recommends the Belkin AC750DB. He says it's the newest technology. Price is $90, and I've heard Belkin is a good brand.
Thank you!!
