If you're troubleshooting an issue with your computer's internet connection, and you see the error message Started Unicast Maintenance Ranging - No Response Received, it means that your computer is unable to communicate with the Dynamic Host Configuration Protocol (DHCP) server. This can be caused by a number of factors, including:
-The DHCP server is down or unreachable.
-There is a problem with your computer's network adapter.
-Your computer is not configured to use DHCP.
To resolve this issue, you'll need to determine which of the above factors is causing the problem. If the DHCP server is down or unreachable, there's not much you can do except wait for it to come back online. If there's a problem with your network adapter, you may need to update its drivers or replace the hardware. And if your computer isn't configured to use DHCP, you'll need to manually enter the IP address, gateway, and DNS settings.
