3 Ways to Get Rid of your Comcast Modem Rental Fee

Updates to this article: I have decided to replace my Comcast Xfinity modem with my own modem + router. I’d recommend buying a fast modem (either a Netgear CM3000 or Motorola B12) and pairing it with a Wi-Fi 7 router (either a Netgear Nighthawk BE9300 or a TP-Link BE9300), if I were buying today. This setup would be as fast as anything Xfinity offers and pay for itself in just over a year (versus Xfinity xFi modem rental fees). Then, it’s free for life! I have more in-depth recommendations on customer-owned replacement devices at the bottom of the article. You can now also get rid of your Xfinity DVR & TV Box fee and save an additional $12 per month ($144/year) by owning your own streaming device.




If you have Comcast (“Xfinity”) internet, this article will instruct you on 3 ways to get rid of your XFinity modem and router rental fee. It’s also a tale of how Comcast has increased their xFi gateway rental fee to a whopping $15 per month ($25/month for “xFi Complete”), in order to turn it into a profitable revenue stream for the company. That’s way too much to pay for a modem rental – so this article will detail 3 ways to get rid of that modem rental fee.

If you don’t have Comcast and have another Internet service provider, the same advice may also apply. I’ve written more broadly on how to get rid of your ISP modem rental fee (if you’re not with Comcast).

How I Found 3 Ways to Get Rid of Comcast Xfinity Modem Rental Fee

When I first moved to my existing home, I signed up for Comcast Xfinity high-speed Internet, with wireless networking (Wi-Fi). As part of the installation, Comcast put in a Netgear cable modem that also dubbed as a Wi-Fi router.

I didn’t know it at the time of installation, but on my first bill, I noticed that Comcast started charging me $3 to rent this modem. That’s right – for the privilege of paying them $40 a month for internet service, I also had to pay $3 per month to rent the equipment to do it (that price has now skyrocketed to $15 per month recently for a standard xFi gateway and $25 per month for “xFi Complete”, sadly).

I was kind of irritated, so I started searching and found a list of Comcast Xfinity supported modems & routers. I couldn’t find any for sale online at the time and thought they could only be had from Comcast.




So, I kept paying the modem rental fee. That is, until they increased their rental fee again (they do this every year or so now). I called Comcast customer service, and threatened to drop the service unless they stopped charging me the rental fee. The Comcast bill negotiation worked. Lesson #1: Negotiation is the first way to get rid of your Comcast modem rental fee.

A year or so later, I started receiving voicemails that Comcast was upgrading to DOCSIS 3.0 (more recently to DOCSIS 3.1). In short, DOCSIS upgrades permit faster download/upload speeds. To celebrate, Comcast kept sending me messages to “upgrade your cable modem for free”. I ignored the messages for a bit out of laziness. Shortly after, I noticed that Comcast stopped charging me for the modem rental fee on my old Comcast-owned gateway completely.

In talks with a Comcast support tech, I found out that this is quite common. Comcast will eventually write off older router/modem/gateways as “customer owned” because they don’t want to support them anymore. The downside when they do this is that they can no longer charge you a rental fee. Lesson #2: Obsolescence is the second way to get rid of your Comcast modem rental fee.

Months and months went by and I thought to myself, “This is great, I have a free Comcast modem/router that I am not paying a rental fee on. I beat the man!”. Meanwhile, Comcast raised its rental fee again.




Then, it happened. Comcast killed my modem. One day it was working fine, delivering serviceable speeds. The next (and for 3 days after), the speeds dropped to 0.2 Mbps download.

I called Comcast Xfinity customer service and scheduled to have a tech come out. He was a bit of a Comcast hater (most Comcast techs are contracted and not employed by Comcast, by the way), and what I learned from him was interesting.

Any other time I’ve had a tech come out, they test things out, look for chewed wires outside, etc. Right away, this tech said, “We have to replace your gateway”. Hmm… that’s odd. I immediately leveled with him and told him I liked my old Gateway because I didn’t have to pay a rental fee. This is when he told me about Comcast pushing the “customer owned” status on old gateways. He told me if Comcast wanted to kill my gateway, they could, no problem, by easily sending it a code. He wouldn’t say they did this to me, but I got the message.

I also got the message when he plugged in a brand new Xfinity-owned DOCSIS 3.0 gateway and it started delivering the full download speed I was paying for immediately, right out of the box.

I then questioned him on if I could buy my own DOCSIS 3.0 gateway (a “gateway” is a modem + router) to replace the Comcast installed gateway. He said, “Yes, any will work”. Years earlier, when I did my search, I did not know this was the case. I thought you had to have a Comcast installed gateway in order to get service. This is not true, but don’t expect Comcast to volunteer that. You can buy any supported gateway or modem + router combo and follow these Xfinity 3rd party modem self-install instructions to get it working. Lesson #3: You can replace Comcast supported gateways with your own modem and router in order to get rid of the rental fee and self-install.

I asked the Comcast tech if he had any recommendations, and he directed me to a Motorola DOCSIS 3.0 gateway (a combined modem and router). And since it is not Comcast owned, they can’t kill it. You can get a modem and router separately, which I would recommend instead, as they are often cheaper and you can upgrade one or the other at some point.

I highlighted the best value modem and router I would purchase at the top of the article (either a Netgear CM3000 or Motorola B12 modem) and pairing it with a Wi-Fi 7 router (either a Netgear Nighthawk BE9300 or a TP-Link BE9300), but any of the following modem and router combinations will work for you. I’ve spent weeks researching every Xfinity supported modem, so you don’t have to do that laborious work. Enjoy – you can do this!

Best Xfinity-Compatible Modems (to pair with any router below):

These cable modems have the latest/greatest technology and will be able to meet the top ISP speeds for a long time. All are top sellers on Amazon with 4+ star customer ratings, are equipped with the latest DOCSIS 3.1 technology, have over 1Gbps (=1,000Mbps, or 1 “Gig”) speed capabilities, and have been chosen for great value for their price. If you’re paying for top speeds with Xfinity, go with one of these.

  1. Netgear CM3000: up to 2330Mbps
  2. Motorola B12: up to 2330Mbps
  3. Hitron Coda56: up to 2330Mbps
  4. Arris S34: up to 2330Mbps

OR, Xfinity-Compatible Modems with Xfinity Voice Capability (to pair with any router below):

In my view, Xfinity Voice is overpriced, with much cheaper VOIP landline options out there that you can connect to any router (see Ooma). But, if you are sure you want it, the following modem is the best Xfinity Voice compatible modem:

Wi-Fi 7 Routers (to pair with any modem above):

I did a breakdown of Wi-Fi 7 versus Wi-Fi 5, 6, & 6E technology. Wi-Fi 7 is easily the best Wi-Fi technology for the modern internet and household Wi-Fi demands. Now that it’s been on the market for a while, it also provides the best value for your money. Compared to Wi-Fi 6E (the most recent generation), Wi-Fi 7 doubled the amount of simultaneous high speed connected devices – and increased maximum speeds. Just make sure you get a tri-band Wi-Fi 7 router, which adds a 6GHz band – not all of them have it. Here are my picks for the best value Wi-Fi 7 routers (all with tri-band) on the market at the moment:

  1. Netgear Nighthawk BE9300 – Wi-Fi 7: up to 9300Mbps (5800Mbps on the 6GHz, 2900Mbps on the 5GHz band, 700Mbps on the 2.4GHz band)
  2. TP-Link BE10000 Mesh – Wi-Fi 7: use solo or as a mesh system with up to 10000Mbps (5188Mbps on the 6GHz, 4324Mbps on the 5GHz band, 574 Mbps on the 2.4GHz band)
  3. Amazon Eero 7 Pro – Wi-Fi 7: up to 5000Mbps (3900Mbps on the 6GHz, unspecified speeds for 5GHz band and 2.4GHz bands)
  4. TP-Link BE9300 – Wi-Fi 7: up to 9300Mbps (5760Mbps on the 6GHz, 2880Mbps on the 5GHz band, 574 Mbps on the 2.4GHz band)

Gateway Modems (modem with router built-in, do not pair with a separate router – 1 “gateway” replaces both modems/routers above): 

As highlighted earlier, you don’t need a modem and router in 1 combo unit (also known as a “gateway”) like Xfinity offers. They work the same as any modem and router combo. They are a bit on the more expensive side, not as reliable, and if you want to upgrade either modem or router functionality, you need to buy an entirely new device (vs just one-half). But, if you want one, this is the one worth getting:

  • Arris G54: up to 2334Mbps modem + Wi-Fi 7 router

So there you have it – there are three ways to get rid of your Comcast gateway rental fee. At the present $15 per month (only a matter of time before they raise it again), the savings is $180 per year. I personally prefer method #3 as the last painful over the long haul and a relatively easy way to permanently get a discount on your Comcast bill.

Update: Comcast is using its Xfinity-leased modems as public Wi-Fi hotspots (at customer’s expense)! Here is how to opt out of Comcast using your modem as a public Wi-Fi hotspot.
