Hi @divya-sc16!
I can help you out with that wireless connection issue!
What exactly is happening on the phone? Did you make any recent changes to the account or phone? Is this occurring in a certain area or regardless of where you are?
There is a great tool that we have to offer on the AT&T website called AT&T Troubleshoot & Resolve. Once on the page, you can select to go through the walkthrough depending on the connection issue you are having, be it for the cellular data or the Wi-Fi connection. You might need to change the make and model of the phone in the upper left corner.
Let me know if this helps resolve the issues you’re having! If you have any additional questions, you can always get back to me through this post! Have an awesome rest of your week!
Tim, AT&T Community Specialist
