If your computer won’t connect to the internet, but other devices on the same network are able to connect, here are some things you can try:

1. Restart your computer: Sometimes, simply restarting your computer can resolve network connectivity issues.
2. Check your network settings: Ensure that your computer is connected to the correct network and that your network settings are correct. You can check your network settings by going to the Control Panel > Network and Sharing Center (on Windows) or System Preferences > Network (on macOS).
3. Check your network adapter: Ensure that your network adapter is enabled and working properly. You can check this by going to the Device Manager (on Windows) or System Information > Network (on macOS).
4. Reset your network adapter: Sometimes resetting your network adapter can resolve connectivity issues. You can do this by opening a command prompt or terminal window and typing the command “ipconfig /release” followed by “ipconfig /renew” (on Windows) or “sudo ifconfig en0 down” followed by “sudo ifconfig en0 up” (on macOS).
5. Disable and enable your network adapter: If resetting your network adapter doesn’t work, try disabling and enabling it. You can do this by going to the Device Manager (on Windows) or System Preferences > Network (on macOS) and right-clicking on your network adapter and selecting “Disable” and then “Enable”.
6. Run a virus scan: Sometimes, malware or viruses can cause network connectivity issues. Run a full virus scan to ensure that your computer is free from any malicious software.
7. Check your firewall settings: Ensure that your firewall settings are not blocking your computer from accessing the internet. You can check your firewall settings by going to the Control Panel > Windows Firewall (on Windows) or System Preferences > Security & Privacy > Firewall (on macOS).

If none of the above steps work, you may need to contact your network administrator or internet service provider (ISP) for further assistance in resolving the issue.
