Follow these steps to troubleshoot your internet connection using command prompt:
Check the physical connections. Verify that the cable connections from the modem to the router are tight and secure.
Check your DHCP settings. See if your dynamic IP address has been assigned.
Test the network connection. Use the ping command to test the availability and connectivity of external IPs.
Test the modem. Ensure that the modem is properly connected and functioning.
Check the DNS settings. Make sure that the domain name and server IP addresses are set correctly.
Check the router settings. Verify the encryption settings and other router options such as the SSID.
Run an ipconfig command. This will confirm the router and DNS settings have been applied correctly.
Reboot the router. In some cases, rebooting the router can resolve the issue.
