Is there a way to increase the device limit on an internet plan?

Hello Eliza_G Thank for reaching out to us for help with the account and services. While working with customers we often find that they are able to use lower speeds from what they currently have, and it truly can help save. I love that you are considering this to help with the rates and to stay with Xfinity! 

While you may see devices that are supported, that is not limiting how many devices can be on your home network, it's a suggestion or reference of how many devices this speed tier can support at a time for certain functions. For example, my home has 40+ wireless devices mostly are smart devices like lights and thermostats, but we have 2 people that work from home, along with our wireless devices like tablets, phones and TV's all connected at the same time. Our home speed is 600/35 Mbps, and it's flawless. 

If you plan on having over 8 devices online and streaming 4K all at the same time, you may seem some latency, but if you have 3 devices streaming with several other devices connected to the network you are not going to have any trouble at all. 

Let's dig into your account and see what options we have to help out. Please send us a direct message with your name and service address. We will need to send a verification code from there, but once we have that completed we can compare the options and figure out what will work best for you. 

Thank you for moving the post to the right support area @EG!
