How to Troubleshoot Charter Internet

By David Somerset

Charter is a company that provides TV, telephone, and high-speed Internet service, though their service is not available everywhere in the country. You may experience issues with your Charter Internet connection if your modem or computer is set up incorrectly. Even if your Internet connection is working, you may be noticing slow download speeds if something is not working correctly. If you are having problems with your Charter high-speed Internet connection, you will need to troubleshoot the connection.

Step 1

Reset the power on the cable modem. Turn your computer off. Unplug the power cable from the back of the modem. Make sure that it is the power cable that plugs into an electrical outlet and not the data cable that is screwed onto the modem. Wait 30 seconds or longer before plugging the modem back in. Verify that the connection light is solid when you plug the modem back into power. Start your computer and attempt to open your Web browser to the Internet to check your connection.

Step 2

Scan your computer for adware, spyware and malware if you are experiencing slow Internet speeds. Purchase or download an anti-malware application online. Norton Antivirus and AVG Antivirus are two useful programs. Run a full system scan and delete any adware, spyware or malware that the security software detects.

Step 3

Ensure that your computer system meets the requirements for Charter Internet service. Verify that your operating system is Microsoft Windows 2000, XP, Vista, or Windows 7 for a Windows computer. Make sure your operating system is either Apple Macintosh 9.x or 10.x if you are running a Mac. Visit the "What Does Charter Support?" link in the References section to make sure your computer hardware is compatible as well.

Step 4

Check your PC limitations. Hold down "Control" "Alt" and "Delete" simultaneously to open the "Task Manager." Select the "Performance" tab and view CPU and page file usage. If these are very close to their maximums your computer may be limiting your Internet speed.
