Windows 10: Question About Lights on Updated Comcast Modem

I didn't know where to post this question, please excuse me if it's in the wrong forum. I have a windows 10 desktop with Comcast internet service.

They sent me a letter awhile back that I needed to update my old modem with their new one. Yesterday I went to their store and connected and activated it, following the instruction booklet. I'm using an ethernet connection to my computer.

Since I installed it, there has been two lights continuously flashing, the 2.4GZ and the 5GZ. I believe on the set up screen I chose the 2.4GZ, as the guy in the store said it didn't matter which one I chose, but generally they use the 2.4.

I posted on the Comcast customer support forum because I really would like to avoid involving a tech if I don't have to. I never got a reply from a Comcast employee, only one from an 'expert' there who said it's nothing to worry about.

I don't think it's okay, because on my old modem no lights were flashing. I don't know much about computers, but I thought someone here could give me their thoughts on this.....thanks.

Comcast - looking for modem suggestions

I guess Comcast is looking for a way to bill me for more money and they're claiming they haven't been charging me $10 a month for modem rental. $41.95 a month, in my opinion, is already way too much for any kind of internet service. I don't want to start paying $51.95 (plus any other hidden fees, taxes they'll try to slap on).

I don't want to pay them extra money for something so trivial.

So, anyone here that uses Comcast have a modem they use they could suggest? I don't need any router, I've got that covered. I just need to get a modem that'll work with Comcast without them pitching a fit that it's "not compatible" with their network.

What bandwidth do you have / want to be able to support?
There are several good models out there with price ranges that scale from moderate to high bandwidth.

You still need a VoIP service provider though, no?
