Hello @user_de0cb7, thank you for taking the time to leave a post. Have you recently brought a new device into your home that connects to Wi-Fi, or had visitors who may have connected to your Wi-Fi?

Recently replaced the Xfinity Wi-Fi gateway.  I am now seeing 4 devices each named CMTX6-64TestPC9 that are currently connected to the gateway.  I see a 5th device named CTDI CMTX connected to the gateway.

What are these devices?

Hi there! If you just set up your new device and are seeing unknown devices, you can use the Xfinity app to check what devices are connected and you can use the app to disconnect these. You can also update your password for your connection as extra security.
