1. Maybe your notebook didn't get the correct IP address. To put it bluntly, the router did not assign an IP to this computer. You can delete the wireless connection settings on this computer, and then reconnect to see if it is successful.

2. There may be something wrong with the driver of the wireless network card. Reinstall the driver, preferably officially.

3. Restart the next router to see if it is successful.

4. Is the wireless network card of the notebook turned off? If so, please turn on the wireless switch.
