Comcast Xfinity VPN is not working

/ / Comcast Xfinity VPN is not working

Some Comcast users have problems using peer-2-peer services. This is because they might be experiencing restrictions or throttling of their internet connections.

Some Comcast routers don’t support PPTP protocol (a commonly used but less secure VPN encryption protocol), so if your VPN does actually get blocked then that will severely compromise  your privacy and security on the internet.

If you suspect that your VPN is dropping due to a poor WiFi connection on your Comcast Xfinity connection then check out our guide over here.

Get yourself the best VPN for your needs

The internet is a wild and dangerous place. The best way to protect oneself from the perils of the digital world are with encryption, authentication, and anonymity services like NordVPN’s dynamic security suite that protects your data online at all times.

NordVPN will help you take back control of your browsing, get rid of the hassles that come with censorship without introducing new problems that negatively impact your internet experience such as buffering and slow loading times.

NordVPN even protects your identity so no one can track what sites are being accessed by monitoring web traffic on a VPN’s network or ISP Internet connection logs! NordVPN does not keep any logs, so your activities are not recorded by anyone.

Privacy has never been more important online than it is today. The internet is a dangerous place, and it’s only going to get worse as cyber criminals continue to target vulnerable connections that do not use any encryption.

NordVPN offers you complete anonymity in the digital world – even if your ISP is throttling or blocking VPN traffic. We will show you some basic steps to get your VPN working again on Xfinity.

If you are having problems getting your VPN up and running with Comcast Xfinity then look below at our troubleshooting guide.

Steps to try

If you are not able to connect your VPN then you may have to contact your internet provider (Comcast Xfinity in this case) to see if they can provide you with information about why it isn’t working.

Before you do, try the steps below and see if you can fix it yourself.

In extreme cases, restoring the default gateway on your router and resetting it back to factory defaults might do the trick(this will clear all saved settings so make sure that you have all of this information if you blank out your router. You will also have to set it up again from scratch, so make sure you understand what you are doing first! ).

You may also want to reboot both your modem and wireless access point while you’re at it. If none of these steps help, then try and look if you have any of these router models below.

Try changing your VPN protocol

Many people don’t realize it, but there are two different ways to use a VPN with 2 different protocols. TCP is a more standard way of communicating on the internet and networks, but UDP is faster and more suited for applications like games and other similar applications.

Common reports from people are very often having problems using their VPN with Comcast, and some people report that they have had some success with using TCP as their communication protocol instead of UDP.

You can change the settings in your router and it is not difficult to do. Simply lookup the process for your specific brand and model of router that is provided on their website.

If you are still having problems with connecting to your VPN over your Comcast Xfinity connection, then we recommend that you can try to change your encryption protocol next. You might want to choose OpenVPN or L2TP/IPsec instead of PPTP. It should be easy to change because most VPNs offer a variety of encryption protocols.

It is important to note that the level of encryption that you use will ultimately affect the speed of your encrypted connection. Stronger encryption means slower speeds because there is added processing time to encrypt and de-crypt data during transmission.

Another thing to try is changing the encryption protocol that your connection uses. Try swapping from WPA-PSK to AES and see if that helps. Alternatively, you can also try out either OpenVPN or L2TP/IPsec).

OpenVPN is seen by many as being  somewhere in the middle, with both strong encryption and normal latency without affecting internet speeds too badly.

If you are able to connect to your VPN, but your performance is not quite what you are looking for then some it is recommended that you switch to an alternative server,  geographical location or IP address.

Selecting a server that is closer to your current location can help to speed things up too, so if you are using your VPN for non-geographical relocation reasons then try choosing a server in a closer area.

Make sure that your WiFi connection is ok

You might be surprised to know that if your WiFi is not stable, then your connection to your VPN can sometimes drop. Better VPNs like NordVPN usually have an automatic reconnect option, so if you get disconnected from the VPN you will automatically be logged back on again once your WiFi is restored.

However, it doesn’t hurt to make sure that all of your WiFi services are working properly, and to achieve this we have written a few articles to help you out.

If your WiFi seems to be dropping more than usual then you could have one of the most common WiFi configuration mistakes set up on your device. We cover that in this article here to get your Xfinity WiFi working reliably again. 

If you can’t connect from your laptop, then read our guide here to see how to fix this common issue with Comcast Xfinity.
