Here we can see, “VPN blocked on Comcast and Xfinity”

  • When it comes to VPN protocols, Comcast routers can be finicky.
  • It’s no secret that Xfinity blocks VPN traffic, and Comcast routers give it the upper hand.
  • A VPN that isn’t working properly can jeopardize your privacy.
  • With the help of the solutions given below, you may get your VPN to operate with Comcast once more.

How can I fix Comcast’s VPN issues?

1. Verify that you’re using an appropriate VPN

This is quite significant. As we’ve previously stated, choosing a decent VPN solution that meets your demands isn’t exactly a walk in the park.

Especially when we consider the fact that the majority of valid solutions are premium. Of course, if you simply need to mask your IP address every now and again, going on a shopping binge isn’t a good idea.

2. Update the firmware on your router

An authoritative source said a specific router model (Technicolor Wireless Gateway for XFINITY Internet Service) experienced PPTP security protocol flaws. According to reports, the problem can be remedied by changing the firmware on your router.

We can’t say for sure that this was addressed because there isn’t a lot of user feedback. However, it’s worth a shot, and the VPN solution should work as intended after updating the firmware on your router.

Xfinity obstructing VPN traffic, on the other hand, is a well-known issue. If you’re wondering how to upgrade the firmware on your Comcast XFINITY router, it’s done immediately after restarting your devices.

Simply wait until the upgrades are deployed before attempting to connect through a VPN tunnel again.

If you have your own router, you can also utilize it to bridge the connection, removing the need for any evasive tactics. Any third-party router will work, and all you have to do is enable Bridge mode in the XFINITY router’s settings.

Type your IP address in the address bar (Comcast altered the private internet subnet from 192.x.x.x to 10.x.x.x) and log in with your credentials. Enable Bridge mode under Gateway > At a Glance.

3. Switch servers, change the protocol, and modify the VPN encryption

Two different protocol suits cover the same issue in different ways. TCP (Transmission Control Protocol) is a common network and internet communication protocol, and UDP (User Datagram Protocol), a more app-oriented and speedier protocol, is also available.

Many people who used the latter reported problems with Comcast routers banning VPN. As a result, even though it appears to be slower, TCP should be your preferred communication protocol. It can be set up in the router’s settings.

Aside from that, we propose adjusting two VPN-specific parameters. To begin, we propose switching from PPTP to OpenVPN or L2TP/IPsec as your encryption protocol. Most VPN packages have several different encryption protocols, so this should be a simple procedure.

Keep in mind that the level of encryption is inversely related to speed. In other words, the better the encryption, the slower the bandwidth will be. OpenVPN sits in the middle, offering both strong encryption and reasonable latency.

You may be throttled by Comcast if you have surpassed your monthly internet service contract’s bandwidth limits, including your VPN connection. This includes transmitting data to your computer via your VPN.

3. Is PPTP blocked by Comcast?

Furthermore, it appears that some Comcast routers do not support the PPTP protocol, which is a popular VPN encryption technology that offers less encryption but lower latency and faster bandwidth. As a result, Comcast’s blocking of VPN traffic is rather widespread.
