My Mi TV Stick Connects to Wi-Fi but Shows "No Internet" Error

Hello, I am experiencing an issue with my Mi TV Stick. While it successfully connects to my wireless network, it keeps displaying a "no internet" error message, and I cannot get it to work properly. I have tried all suggested fixes, including updating the date and time settings and forgetting and reconnecting to the network, but the problem persists.

This situation is highly frustrating as the device is essentially unusable in its current state. I purchased this product with the expectation of reliable performance, but that has not been the case.

I need immediate assistance to resolve this connectivity issue. Please provide a clear solution so I can use my device as intended.
