Home   >   Blog

Over 31 million customers turn to Comcast Xfinity for their broadband Internet, landline phone services, and cable TV. Comcast customers enjoy excellent speed and service thanks to their large network of fiber optic and coaxial cables.

What Comcast users are lacking is guaranteed privacy and security. For that customers need to turn to a virtual private network or a VPN. Not only will a VPN for Comcast ensure your online activities remain private, but it also protects Comcast users from lag caused by ISP bandwidth throttling and allows Comcast users to access geo-restricted websites around the world.

In a hurry? Here are the best VPNs for Comcast

About Comcast

Comcast is one of the largest Internet companies in the United States, providing broadband Internet, phone service, and cable TV to millions of customers. The large network of underground fiber optic cables provides Comcast customers with fantastic speed and highly reliable connections.

In addition to their home services, Comcast Xfinity provides digital phone service, e-mail addresses, cloud storage, WiFi hotspots, and anti-virus apps.

Comcast Xfinity-based services keep millions of Americans hooked up to the World Wide Web!

What is a VPN?

A VPN is a virtual private network that reroutes Internet traffic through an encrypted VPN tunnel via a remote server. When you connect to a VPN server, your true IP address is hidden and replaced by a virtual IP provided by the VPN service. This allows your location and all of your data to remain private and secure.

When you use a VPN for Comcast Xfinity, you are protected from hackers, snoops, and government surveillance. Even Comcast can’t see what its customers are doing, so users are safe from speed throttling or having their browsing history sold to a third party.

When you connect to a remote server in another location, you can access all of the websites in your virtual location that would otherwise be blocked. It’s a great tool for travelers who want to access their work or bank accounts back home, as well as movie buffs who want access to geo-restricted streaming content worldwide.

Why you should use a VPN as a Comcast user

Comcast customers turn to VPNs for Comcast Xfinity for any number of reasons. Here are the most common:

Speed

While using a VPN can lower your Internet speed, it’s nothing compared to the slowdowns you’ll get when Comcast uses bandwidth throttling on customers using too much data. Avoid the slow speeds you get when Comcast throttles your service by hiding how much data you are using by passing it through a secure VPN tunnel.

Security

As your Internet service provider, Comcast can see everything you do online. If you want to protect your browser history, downloads, and other online activities from Comcast, the government, hackers, and snoops, be sure to use a quality VPN to encrypt your data.

Cost

Comcast customers get a limited amount of data every month, depending on the plan they select. If a Comcast user goes over their monthly limit, they can get hit with heavy fines. When you use a VPN for Comcast Xfinity, your Comcast bandwidth usage is hidden, so they can’t tell that you’ve gone over your limit, and you won’t get charged any extra fees.

Global access 

Certain websites, especially torrent search engines and streaming sites, may get blocked by Comcast Xfinity. You can bypass these restrictions by connecting to a remote VPN server in another region that is not blocked.

Streaming

Online streaming platforms like Netflix purchase streaming rights that are country-specific. To uphold copyright law, these sites use geo-blocks to ensure the content can only be accessed in the country it is licensed for. Comcast users can connect to a VPN server in a different location to access the content in that region, providing VPN access to a huge library of global content.     

What are the security risks for those using Comcast services?

Comcast customers are turning to VPNs for protection against a variety of security risks, as Comcast has gained a reputation for engaging in data leaks, traffic monitoring, and other privacy violations.

Information breach

Like all of the biggest Internet service providers, Comcast customers are a target for online hackers, and Comcast Xfinity hasn’t always been able to protect its users.

In 2015, the personal account details of more than 75,000 customers were leaked. In October of 2023, over 35 million Comcast users’ data, including usernames, passwords, and contact details, was compromised.

When you use a reliable VPN for Xfinity, all of your Internet traffic is funneled through a secure, encrypted tunnel, ensuring your data remains secure.

State monitoring

The US government has been exposed by whistleblowers for illegally spying on citizens by tapping into ISP networks. In other words, they could monitor your Internet connection without your knowledge or a warrant.

Comcast Xfinity users can protect their Internet traffic from the prying eyes of the government by using a secured VPN to send all of their data through an encrypted tunnel that the government can’t access.

Hackers

Cybercriminals are always on the lookout for sensitive information like financial records, passwords, social security numbers, and other personal information they can use to their benefit. Comcast customers can protect themselves by making all of their data indecipherable to hackers through an encrypted VPN connection.

ISP surveillance

ISPs have access to your entire browsing history and may sell it to a third party without your knowledge or permission to increase their profits. This practice makes Comcast Xfinity users more vulnerable to phishing attempts, malware, and hackers.

A good VPN encrypts all of your data so even your ISP can’t see what you are doing online, keeping you safe from ISP tracking and its possible consequences.

Network blocks

Comcast Xfinity users may get blocked from some websites that conflict with the company’s political or corporate interests. When you connect to a VPN server using a dependable VPN provider, your traffic is rerouted through an encrypted VPN tunnel so you won’t get blocked.

Excess charges

On the majority of Comcast packages, users will get charged if they overstep the 1TB of data limit per month. VPN users can avoid these fees by encrypting their online activities, so Comcast won’t know if they used more than the allotted data.

Privacy breaches

Comcast uses Deep Packet Inspection to monitor all of your Internet traffic and keeps logs of everything you do online, including the websites you visit, the apps you use, and the customer service you receive.

Comcast customers looking for online privacy need to use a VPN, which encrypts all of your data and protects you from accidental leaks.

Public Wi-Fi vulnerability

Free public WiFi is a hunting ground for hackers looking to exploit their notoriously poor security standards. Next time you join public WiFi in a coffee shop, hotel, or airport protect yourself by using a high-quality VPN that will encrypt your usernames, passwords, financial information, etc, and keep it out of the hands of hackers.

Bandwidth throttling

After the abolishment of net neutrality in 2017, Comast can and will use ISP throttling if it feels you are using up more than your fair share of data. The ISP throttling could be up to 90%, which leads to issues like buffering, lag, pixelation, or dropped connections.

A VPN protects you from ISP throttling Internet speeds by encrypting your VPN traffic. Since Comcast Xfinity can’t see what you are doing online or if you’ve gone over the data caps, there won’t be any reason to engage in bandwidth throttling.

Can I use a free VPN for Comcast?

It is possible, but not recommended, to use a free VPN for Comcast Xfinity. Free VPNs do not offer the same level of privacy and security features that you get with a trusted subscription plan like those we recommend. In fact, many free VPNs will earn their profit by selling your browser to the highest bidder, making you even more vulnerable to hackers and phishing attempts.

Most no-cost VPNs will limit speed, data, and bandwidth to keep their expenses low, which leads to lag, buffering, and/or dropped connection.

Finally, free VPNs are far less reliable at bypassing geo-blocks, as they are easily flagged as VPNs, leading to denied access to restricted sites.

How we picked and tested VPNs on the list

We had a team of experts look at a multitude of VPN services and analyze them based on the following criteria to select the top 3 VPNs for Comcast.

  • Speed. We selected VPNs that demonstrated enough speed to support uninterrupted browsing, streaming, gaming, and torrenting.
  • Privacy and security. Our recommended VPNs offer the gold standard in privacy and security, including military-level encryption, secure VPN protocols, an independently verified no-logs policy, a kill switch, RAM-only servers, and DNS & IP leak protection.
  • Unblocking capability. All of the VPNs on our list have a solid track record for bypassing geo-blocks on popular streaming services and other geographically restricted websites.
  • Server network. We gave preference to providers with a vast server network to avoid server overcrowding and allow for broad access to content across the globe.
  • Compatibility. Our preferred providers have easy-to-use apps that work with all major operating systems and allow for multiple simultaneous devices on the account.
  • Customer service. To make our list, the VPN service must include a money-back guarantee and 24/7 live chat support.
  • Price. We prioritized VPNs that provide a good value for services rendered.

Should I use a VPN on Xfinity Comcast routers?

When you set up a VPN on your Comcast Xfinity router, not only do you get a secure internet connection on all of your household devices at once, but you also get coverage for devices that don’t support VPNs, like your gaming consoles or smart TVs. Unfortunately, Comcast routers, including xFi Gateway, Netgear, Arris, Linksys, and Motorola, don’t support VPNs.

How to set up a VPN on Xfinity Comcast router

Keep your modem and Wi-Fi router separate when using Comcast Xfinity routers, rather than using one of the cable modems with built-in Wi-Fi. Most of the Comcast modems, including Xfinity Gateway with built-in routers are not compatible with VPNs, including xFi Gateway, Arris, Linksys, Motorola, and Netgear.

Most routers support OpenVPN or one of the other common VPN protocols, but if it doesn’t, you will have to install the firmware manually. Options include AsusWRT, DD-WRT, OpenWRT, or TomatoUSB, all of which can be found online. Follow the manufacturers installation instructions carefully so as not to permanently damage your router. Make sure bridge mode is enabled on the wireless gateway.

Once your router is fully VPN compatible, follow the instructions from your VPN provider for set-up, as it varies depending on your specific firmware version and VPN service. In general, here’s what you will need for set-up:

  • Username
  • Password
  • IP address of the server
  • UDP or TCP Tunnel protocol
  • Encryption cipher
  • Hash algorithm
  • Shared key of certificate
