Two Modems on one account

Is it possible to run 2 modems on one account, since I just got the xFi modem from Comcast and still have my Netgear modem that works fine and could use it in a different part of the house. If not, Why?

Why?  Money.  Likely they have a limited IPV4 address space pool.  Some residential locations used to be able to get multiple lines -- they charge you for provisioning each one of course, but I don't think you can do that most places anymore.

It would be kind of pointless anyway.  You can get connectivity other ways to locations in your house.  Ethernet, MoCA, powerline, mesh networks, etc. and it would cost you less than two service accounts.

Hi @user_b27127

 

I appreciate you reaching out about having two modems. Your residential account is allowed only one modem if you are concerned about the coverage to the other part of your home, you could use an additional router or even check out our xFi pods https://www.xfinity.com/learn/internet-service/wifi/xfi-pod for additional coverage.

@XfinityLysa​ didn't want to have to pay for anything else, since I have that Netgear modem I thought I could put it to good use. BTW, why does Comcast not allow 2 modems on one account?

Thanks for those additional details. We do not allow our residential account to have multiple modems as having two modems in proximity together can cause interference and issues with your connection. Think of it like you have two speakers close together, and feedback happens. It makes the sound quality you were hoping for disintegrate. Let us know if you have any additional questions regarding your connection. We are here to help.

I wonder what your goal was to have a second modem/router combo. Were you hoping to have two separate networks in your house? If you had more than one family at your residence (like you rent out a room or have an additional dwelling unit), I could see having two accounts and two modem/router setups so long as the two networks are kept separate. However, connecting a second modem/router to a single network would be problematic. Both routers would have DHCP servers enabled by default, so you would have to disable one. Next, you would need some routing plan. For example, if you wanted to browse Google from a desktop, which modem/router path would be used? I've seen this done in a commercial environment where load balancing and having a backup router/ISP were desired. That's getting pretty sophisticated. 

On the other hand, if you were hoping to get better wireless coverage, consider putting the Netgear into bridge mode. Besides the router that connects to the modem, I have a Netgear Orbi router in bridge mode (and a satellite) for general wireless coverage and a separate TP-Link WiFi 6 router in bridge mode that I use with a Quest 2 for wireless connections. The latter two routers act as fancy wireless access points.

The netgear still might have merit too.  Depending on which one, and which firmware, some of them can be configured as a WiFi repeater or WiFi access point if you are trying to extend coverage.
