<human>:  How do I troubleshoot my computer if it is not connecting to the internet?
<bot>: The first step in troubleshooting your computer's connectivity to the internet is to check the cables and wireless connections. Make sure all the connections are secure and that the modem is powered on. If the connections seem to be in place, try restarting your computer. If the issue persists, you should check to see if your computer is connecting to any other network or find out if your browser's proxy settings are blocking the connection. If all else fails, you may need to contact your internet service provider for assistance.
