I too have the same issue as everyone else. I just bought a brand new HP Pavilion Laptop and after pulling it out of the box, it stopped on the 4th screen where it would consistently attach to wifi but always said "Connected, No Internet". After doing the tricks listed on how to breakout of the initial Windows 11 setup (Shift+F10, type 'taskmgr', click 'more details' on the task manager and then killing/ending the "Network Connection Flow" process/task), Windows 11 proceeded to the main screen. I immediately rebooted it and then disabled the 802.11ax protocol which was the root cause for me. For some reason, Windows 11 did not like my WiFi6, ASUS router so I changed the protocol to 802.11ac and have never had a problem since. To do that in Windows 11, you must:
- Click the Search icon / magnifying glass
- Type "control panel"
- Click "Device Manager"
- Go down to "Network Adapters" and expand that section
- Highlight and double click on your wi-fi adapter (it has unique names depending on your hardware manufacturer)
- Click the "Advanced" tab
Change the wireless mode from 802.11ax to 802.11ac, reboot and see if it changes from "Connected, No Internet" to just Connected (with internet).
That's what fixed my issue after I spent a few days troubleshooting the wifi, "Connected, No Internet" problem.
Good luck!
