Q: Will this 'plug and play'? I just hook it up and return my Comcast unit; no hoops to jump through?

A: After you plug it into power, the tv, and cable box, you have to call comcast and tell them the information from the bottom of the unit. I called on Labor Day and got someone who couldn't find it, but the next day I called and had no problem. Save that innformation. You'll need it to set up wirelesss for your devices and printer. You can take the old unit to a comcast "store" or they can email you a label and you take it to a ups store where they box it up and give you a receipt.

Q: will this work with Spectrum

A: Yes. They’re on the approved modem list.

Q: Is this the same unit that Comcast provides? It looks exactly the same as the unit I currently have.

A: I would say yes however stopping by your local Xfinity store they won’t give you any information since they want to rent you their version. This is the second router I bought from Best Buy the first one was almost 4 years ago it was the same one xfinity was renting at the time. It was $200.00 so if you do the math the rental would have been $500.00 plus Best Buy has a recycling program where I received a $50.00 credit toward the purchase of the new router. Hint: bring your old one back at the same time you plan on buying the new one they give you the credit voucher that you take to the register with the new one. Also if you are planning on buying the Xfinity WiFi extenders they claim they won’t work with any router but theirs, this is no problem you can buy google extenders at Best Buy. I haven’t yet, the router works fine without them. Finally most people don’t realize that those xfinity hot spots are signals they use from your rented router which you agree to knowingly or not in your rental agreement. They can’t bounce off your owned router another reason to own your router.

Q: Is this the exact same wireless gateway Comcast uses for my triple play plan? The photos look nearly identical.

A: Don't know what Comcast uses for $11 a month, but I purchased used this modem/router for the Comcast triple play and it works great. The installer would take no responsibility as he wanted me to rent the Comcast modem router, but it was easily set up, and works great.

Q: I am looking into the NIGHTHAWK HIGH SPEED CABLE MODEM ROUTER + VOICE Model C7100V. I currently have a XFinity provided modem-router. If I bring this product home and plug it in, should it start working without calling xfinity?

A: I did the activation myself, but it wouldnt accept it. called comcast and they gave my the run around because I wouldnt rent one from them. They said they wouldnt be able to activate it because it 3.0 not 3.1 waited an hr on hold for supervisor and sure enough it got activated. Works great. Comcast is full of crap. I work with electronics for a living. Dont let comcast sway you to return this and rent one monthly!

Q: Hello. I recently purchased a NETGEAR Nighthawk AC1900 WiFi (Model No. C7100V) and would like a backup battery for the unit. Do you sell these? If so, please provide the product number for ordering. If you do not sell these, where might I find one?

A: I know COMCAST rents them to users who rent a comparable Netgear unit, but the Comcast guy said they get a flow of returns / replacements. I did research on AMAZON and found complaints ... the battery backup units didn't hold a charge very long, or such. They are pretty small. So I purchased and connected to my CV7100 a larger and more robust APC BACK-UPS Connect model BGE90M 120 V Network backup (with USB charging ports) for a little over $30. It had much better reviews, has more power, is about 1/2 the size of a shoe box, has a built in lightweight surge protector, has three output two prong plugs, allegedly runs 4.5 hours, and has an ON OFF switch so that if the power goes out, you can ration battery power to simply run your VOIP and MODEM/ROUTER functions. The internal sealed lead acid battery is replaceable. Wt est 7 lbs. Much better than the insertable junk that fits inside the Netgear. So far so good.

Q: Does this modem help your internet speed? Every since Comcast brought me a new modem, my internet speed is terrible! I need help!

A: I have had Xfinity now for a few weeks now. I have used the Nighthawk modem from the beginning. I have been running right at 1 Gig speed. I would highly recommend making an appointment with "The Geek Squad". They can optimize this modem to perform optimally. I do not work for them I just know they can quickly sort this out for you as they did for me. Hint: Make your appointment in person. The Geek Squad are located in your local Best Buy Store. Hope this helps.

Q: Why isn't this product listed as a cable modem router with voice on the best buy web site? The listed name makes it seem like it is just a router. Only looking at the description does it tell you its a modem.

A: It's definitely a cable modem... i just purchased one because i've been renting my comcast modem, and they won't let me return it unless I either cancel the phone on my account, or put this modem at my home... it will be here in a few days!
