Wifi connected no internet

@XfinityChe​ yes. I still lose connection .   Connection is intermittent.  I lose connection more often than staying connected .  My router is directly below  my smart tv . Iv been with Comcast for over a year with the same data service and router ,  just a week or so ago I have been experiencing this . 

Thanks for that information, @user_24b15a! As you have mentioned you have tried some general troubleshooting in a different thread, it looks like we will need to take a closer look into this. Can you please click the Direct Message icon at the top right of the page, click on the pen and pad icon and enter Xfinity Support in the "To" section of the chat and provide us with your first/last name and full address so we may further assist you?

@XfinityMichaelC​ Wife and I have iPhones (12 & 13).  Both have full strength connections to our Xfinity home wifi, but have no connection to the internet.  Tried several hard resets of the modem, but problem still remains.  All internet connections using the ethernet  work fine. Only our iPhones using home wifi have no internet connection.

I am not sure what the cause is or if there is a better solution. I have had the same issue since upgrading to the gigabyte plan with Comcast. I had to manually assign static IPs for the devices. then when connecting to the wifi i had to manually enter gateway, ip and dns. Then i was able to get an Internet connection on said devices. that has been my go-to for the past year and has worked
