My computer can't connect to the public WiFi of the apartment, but my mobile phone can. The mobile phone turns on the hot spot.

When the notebook can't connect to the wireless network, it is suggested to eliminate it by the following methods:

1. Verify that the password is required for the wireless network and is correct. If you don't know the password of the wireless network or enter an incorrect password, you will not be able to connect to the wireless network.

2. If the password is confirmed to be correct, it is recommended to turn off the windows firewall.

3. Verify whether the network environment is normal If there is a problem in the network environment where the notebook is located, there will also be a phenomenon that the wireless signal cannot be connected after searching.

Verification method:

Method 1: After restarting or resetting the wireless router, observe whether you can connect to the wireless network. If you can connect to the wireless network, it means that it is caused by the router setting problem, and you can rule out the laptop problem.

Method 2: Observe whether you can connect to the wireless network after changing other network environments. If you can connect to the wireless network, it means that there is a problem in the previous network environment or the router itself, and you can also rule out the problem of the laptop.

4. If all the above settings are checked, you need to reinstall the wireless network card driver.

5. If it still doesn't work, it is recommended to back up important data and reinstall the operating system.

6. If all the above methods fail, it is recommended to take the purchase invoice, maintenance card and machine to the service center designated and authorized by Samsung for testing and judgment.
