Smart Devices Disconnected, Cannot Reconnect

I noticed that all of my devices were disconnected from the wifi. All of them. My phone, my PC, and various smart devices. 

Everything that can connect to the wifi itself, e.g., my phone and computer, could easily just reconnect. However, those devices that I connected to my internet by accessing their own “wifi” through an app and then connecting them to my wifi will not come back. I have restarted those devices and my router to no avail. 

I have a digital frame, a camera, and various smart plugs. All connect to the wifi in the same way, and none of them can connect since all devices were disconnected.

The same thing is happening to me. Almost all of my smart home devices have disconnected from the wifi.

Hello user_tfnpem. Thank you for sharing your experience with the devices disconnecting from the home network. I'm sorry to read of this happening for your home. I know how important it is to have a solid reliable connection and any hiccup can create a poor experience. I would love to help out to see what is causing the trouble. Sometimes a simple modem reset is needed and devices would typically automatically connect. However, if that is not the experience let's dig into and to see what happened. I know it's been a couple of days, are the devices still having trouble with making the connection?

Thank you for reaching out and for being a valued Xfinity customer. I hope, besides the network issues, you've had a great day so far. I understand you noticed your devices were no longer on your network and were disconnected. Additionally, these devices have not been able to reconnect like before. I appreciate you taking the time to troubleshoot and restart all your devices. 

 

I'm sure this has been challenging to navigate, but you're in good hands. We are a full-service team, so you've come to the right place. Have you also attempted to reset your Xfinity Gateway? This can be done manually by unplugging, or you can even reboot the device using the Xfinity App, which is a great tool to help troubleshoot. When you try to reconnect these devices, do you get any error messages or alerts?

I am having similar issues. Only certain devices disconnected at about the same time and will not reconnect. Other devices on WiFi are fine. Have tried resetting gateway via Xfinity app, reset button and unplugging. It's as though a security update was pushed out and is restricting or blocking those devices. Automated AI assistant tries checking and says it will check back in two hours with possible help from technician but never does.

@user_8pwnkk​ I realized that all devices connected to the 2.4GHz band were the ones that dropped. I brought my router to the Xfinity store and exchanged it for a new one. My devices that needed the 2.4GHz band immediately recognized it.

Did you get the same exact model or a different one ? What's the number ?

Thank you for reaching out to us @user_8pwnkk! I see @user_tfnpem mentioned swapping their wireless gateway resolved this issue.

 

I wanted to make sure we checked back with you to see if you’re still experiencing this issue and check if you’ve swapped out the wireless gateway since responding to user_tfnpem's message.
