What is Error Code 721
An error code is a code that is displayed on a device when an error has occurred. There are various error codes that can be displayed on different devices, and each code has a different meaning.

One possible cause of error code 721 is a problem with the cable modem itself. If the modem is not functioning properly, it will not be able to connect to the internet. This can be caused by a number of things, including a power surge, or physical damage to the modem. If the modem is not working, it will need to be replaced.
Another possible cause of error code 721 is a problem with the computer that is trying to connect to the internet. If the computer cannot connect to the internet, it will display an error code.

What causes Error Code 721
When you experience Error Code 721, it is typically caused by a problem with your internet connection. This can be due to a number of factors, ranging from a poor connection to your ISP to a problem with your home networking setup. In most cases, you can resolve the issue by following a few simple troubleshooting steps.
One common cause of Error Code 721 is a problem with your DNS settings. DNS, or Domain Name System, is what allows your computer to connect to websites using easy-to-remember addresses instead of IP addresses. If your DNS settings are incorrect, you may not be able to connect to certain websites, or you may experience slow or intermittent connections. You can usually fix this problem by changing your DNS settings to use the OpenDNS or Google DNS servers.
Another possible cause of Error Code 721 is a firewall issue. If you have a firewall enabled on your computer, it may be blocking your ability to connect to the internet. To check if this is the case, try temporarily disabling your firewall and seeing if the problem goes away. If it does, you’ll need to add an exception for the website or service you’re trying to access in order to regain full access.
Finally, a less common but still possible cause of Error Code 721 is a problem with your ISP. If you’ve been experiencing problems connecting to the internet for a while, it’s possible that your ISP has configured something incorrectly on their end. In this case, you’ll need to contact them directly and ask them to help you troubleshoot the issue.
If you’re still seeing Error Code 721 after trying all of the above steps, there’s unfortunately not much else you can do on your own. However, error code 721 messages can also be caused by temporary issues on the website or service you’re trying to connect to. In these cases, simply waiting a few minutes and then trying again will usually fix the problem.
