Why does my phone say no internet connection when i have wifi

(Hope this helps can I pls have brainlist (crown) ☺️)

Explanation:

WiFi connection but no Internet is sometimes caused by an old, obsolete, or damaged network driver. A little yellow mark in the name of your network device or network adapter can often signal a problem.

Go to "Reset options" in the Settings app. Select "Reset Wi-Fi, mobile, and Bluetooth" from the drop-down menu. Tap the "Reset Settings" button at the bottom of the following page. After rebooting, connect to the WiFi network to verify whether the problems have been resolved.

Turning it off and on again is the basic rule of IT troubleshooting; it solves roughly half of all issues. So, even if your phone is linked to the Wifi router, it is not connecting to the internet. Turn the Wifi toggle off and on again in the settings to see if it cures the problem.

There might be a number of reasons why your internet isn't working. It's possible that your router or modem is out of date, that your DNS cache or IP address is corrupted, or that your internet service provider is experiencing outages in your region. A malfunctioning Ethernet cable might be the source of the problem.
