Comcast Xfinity is Using your Router as a WiFi Hotspot, at your Expense. Here’s how to Opt Out.

If you need any further motivation to get rid of your overpriced modem rental fee, I just unearthed a big one. Ever wonder how Comcast’s Xfinity WiFi is able to provide so many public WiFi connections? Well, it turns out that if you are leasing a modem from Comcast (or other ISPs), they are likely using it as a public WiFi hotspot, without you even knowing it.

And it gets better…

Not only are you paying an outrageous $14 per month ($168 per year) with the latest Xfinity modem rental fee increase on top of your overpriced internet package to lease a sub-par modem, but Comcast is then using that very same modem that you are being overcharged for to provide the revenue-generating Xfinity WiFi service to other customers.

On the Xfinity WiFi page, they are giving potential customers the opportunity to purchase “On Demand” use of your modem for the price of:

  • $3.95 one hour pass
  • $4.95 two hour pass
  • $8.95 daily pass
  • $19.95 weekly pass
  • $54.95 30-day pass

AND it could be slowing down your overall speed. At any given moment a limited amount of bandwidth can go through your device.

AND it’s been estimated that there is an incremental cost of electricity for using their 2 antenna modems, even if nobody is connecting to your modem other than you.

AND they are doing it without your permission by automatically opting you in via their terms of service (there is a way to opt-out your modem from Comcast public wifi hotspot use, which I’ll detail in a bit). I mean, why not offer to wipe out customers leased modem fees (or at least provide a discount) if they opt in to using the modem as a public WiFi hotspot?

Do you feel your blood starting to boil? Comcast has a long history of sticking it to its customers, from overpriced leased modem rental fees (and even erroneous modem rental fees when you have your own unit), to never-ending price increases, and painful price negotiations, and other customer service battles.

So, let’s stick em back.

How to Opt-Out or Disable your Comcast Public WiFi Hotspot

Disabling or opting your modem out of the Comcast Xfinity public WiFi hotspot network is fairly simple on the surface, but there have been reports of customers running into issues, and you may have to periodically re-opt-out. Go here to manage your preferences and “turn off” (it is turned on by default).

If you run into issues, call Comcast customer service at 1-800-934-6489.

The Best Way to Turn Off Comcast’s Public WiFi Hotspot: Get Rid of your Leased Modem

Disabling the Comcast Xfinity public wifi hotspot feature is one way to prevent your modem from being used as a hotspot. However, it still leaves you with an overpriced modem rental fee and a device that uses more electricity than a typical modem/router combo.

There are a few ways to get rid of your Comcast modem rental fee, but my best recommendation is to simply replace a leased Comcast modem with your own. It’s been estimated that over 90% of Comcast customers lease their modem, which is a costly mistake.

I have personally replaced my Comcast modem with my own modem + router. Any of the following combos will pay for themselves in the first year (compared to a leased router/modem), and then would be free for life after. And the setup and switch was simple enough for anyone to do. Customers of other ISPs can also cut their modem rental fee.

All are priced around $90 and under, compatible with Xfinity Comcast (& many other ISPs), and are top sellers on Amazon.

  1. ARRIS SURFboard SB6190 (32×8) – up to 859 Mbps
  2. NETGEAR CM700 (32×8) – up to 935 Mbps
  3. Motorola MB7621 (24×8) – up to 845 Mbps

If you want 1 Gbps+ speeds, go for the Motorola MB8600 or Arris SB8200 (pricier).

If you want 1 Gbps+ speeds + Comcast Voice, go for the Arris T25 or Netgear CM1150v (even pricier).


All handle speeds of at least 300 Mbps + 900 Mbps with dual band (2.4 & 5 GHz, respectively), strong WiFi range, & are highly rated Amazon best sellers, under $75.

  1. TP-Link WiFi 6 AX1500
  2. Netgear Nighthawk AC1750
  3. TP-Link AC1750
  4. ASUS AC1300

So do yourself a favor – cut your Comcast bill while simultaneously preventing Comcast from driving up its profit margins on your back.
