1. First, right-click my computer or computer icon, select Manage, and then select Device Manager to check whether the wireless network card driver is installed and whether the wireless network card is disabled.
2. If it is confirmed that the wireless network card driver has been installed and the wireless network card has not been disabled, it is recommended to verify whether the network parameters are set correctly, such as IP address and DNS server settings.
3. You can also change the network environment to see if you can surf the Internet, or use other computers to test whether you can surf the Internet in this network environment and confirm whether there is any problem in the network environment.
4. If there is no problem in the network environment, it is recommended to close the windows firewall and observe again.
5. If windows closes the firewall, it is recommended to download and install the wireless network card driver suitable for your own model and operating system through Samsung official website.
6. If reinstalling the wireless network card driver still fails, it is recommended to back up important data and reinstall the operating system.
7. 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.
