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 Arris S33 modem and pairing it with a TP-Link AX3000 (Wi-Fi 6) or TP-Link AXE5400 (Wi-Fi 6E) router 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 $10 per month ($120/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.

Comcast Xfinity modem rental fee

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”).

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 voice mail that Comcast was upgrading to DOCSIS 3.0 (more recently 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 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 (Arris S33 modem and TP-Link AX3000 router (Wi-Fi 6) or TP-Link AXE5400 (Wi-Fi 6E) router, but any of the following modem and router combinations will work for you. I spent days 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 a router below):

The following modems have the latest tech and will be able to meet top ISP speeds for many years. All are Xfinity-supported, top sellers on Amazon with 4+ star customer ratings, offer the latest DOCSIS 3.1 technology, close to or well above 1 Gbps (=1,000 Mbps) 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 modems:

  1. Arris S33: up to 2330Mbps
  2. Netgear CM2000: up to 2330Mbps
  3. Netgear CM1000: up to 1000Mbps
  4. Arris SB8200: up to 957Mbps

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

In my view, Xfinity Voice is not worth the money, with much cheaper VOIP landline options out there that you can connect to any router (see Ooma). But, if you want Xfinity Voice for some reason, the following modems are Xfinity Voice compatible and supported and use the latest DOCSIS 3.1 technology:

  1. Netgear CM2050v: up to 2330Mbps
  2. Arris T25: up to 949Mbps

Wi-Fi 6 Routers (to pair with a modem above):

Wi-Fi 6 routers are good for households that connect up to 8 devices at once. These Wi-Fi 6 routers all handle 1Gbps+ speeds, offer great value, and are highly rated Amazon best sellers with 4+ star customer ratings. All offer great value and very fast speeds – and will work with any ISP-compatible modem.

  1. TP-Link AX3000 – Wi-Fi 6: up to 3000Mbps (2402Mbps on the 5GHz band + 575Mbps on the 2.4 GHz band)
  2. Netgear Nighthawk AX1800 – Wi-Fi 6: up to 1800Mbps (1200Mbps on the 5 GHz band + 574Mbps on 2.4 GHz band)
  3. TP-Link AX1800 – Wi-Fi 6: up to 1800Mbps (1200Mbps on the 5 GHz band + 574Mbps on the 2.4 GHz band

OR, Wi-Fi 6E Routers (to pair with a modem above):

Want to future-proof your router? Wi-Fi 6E routers are best for households that connect more than 8 devices at once (think larger families or really plugged in smaller families). I recently took a look at the new Wi-Fi 6E versus Wi-Fi 6 versus Wi-Fi 5 technology to determine if Wi-Fi 6E is worth the cost (6E adds a 6GHz band to the prior 5GHz and 2.4GHz). Comcast has recently been advertising its Xfinity “Supersonic Wi-Fi” offering. Broken down, “Supersonic Wi-Fi” is really just Xfinity’s fastest (and highest cost) internet tiers (Gigabit or Ultrafast plans) paired with a new Wi-Fi 6E router (which they are marketing as the “Supersonic Gateway” as part of their package Xfinity “Supersonic Bundle” deal). Here are the most popular Wi-Fi 6E routers on the market at the moment:

  1. Asus AXE7800 – Wi-Fi 6E: up to 7800Mbps (2402 Mbps on the 6GHz, 4804Mbps on the 5GHz band, 574 Mbps on the 2.4GHz band)
  2. Netgear Nighthawk AXE 7800 – Wi-Fi 6E: up to 7800Mbps (2402 Mbps on the 6GHz, 4804Mbps on the 5GHz band, 574 Mbps on the 2.4GHz band)
  3. TP-Link AXE5400 – Wi-Fi 6E: up to 5400Mbps (2402 Mbps on the 6GHz, 2402Mbps on the 5GHz band, 574 Mbps on the 2.4GHz band)
  4. TP Link Deco AXE5400 Mesh Wi-Fi 6E: a mesh system up to 5400Mbps (2402 Mbps on the 6GHz, 2402Mbps on the 5GHz band, 574 Mbps on the 2.4GHz band)
  5. Amazon eero Pro – Wi-Fi 6E: up to 1600Mbps

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

As explained earlier, you don’t need a modem and router in a combo unit (aka “gateway”) like Xfinity’s. 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, check out the following devices:

  1. Arris G36: up to 2330Mbps, Wi-Fi 6
  2. Netgear CAX30: up to 949Mbps, Wi-Fi 6

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.
