How to Check My Internet Connections
It is possible to check your computer's Internet connection to pinpoint issues that may be preventing you from connecting to a network. Microsoft's Network Diagnostics tool can identify these problems and fix them automatically for you. There are a number of reasons you may not be able to successfully connect, so diagnosing the problem will require you to utilize this tool and to verify the wiring of the router, then resetting it. You can check your Internet connection without having to pay for an expensive visit from a technician.
Run the Diagnose and Repair utility. Right-click on the network icon that is located in the bottom-right corner of your computer screen, then select "Diagnose and Repair" from the pop-up menu. The tool will automatically begin scanning your computer for any connectivity issues, then correct them for you automatically.
Verify that all of the router's cables are properly connected. Check to see that the router is connected to either the phone or cable line, then to a functional phone jack or cable outlet. Check to see that all of the lights on your modem are properly illuminated, and that you do not have a DSL filter between the the device and the phone jack.
Reset the modem or router by unplugging its power cord, then plugging it in after 10 seconds. Some modems and routers may require more time being unplugged before the device will reset itself, so refer to the instructional manual for specific instructions for your model.
Verify the functionality of the router. Click on the link for the Internet Connectivity Evaluation Tool that is provided in the "Resources" section below. Check the compatibility of the router with your version of Windows by clicking on the link for the "Windows Logo'd Products List" that is provided in the "Resources" section.
Contact your Internet Service Provider to make sure that there is not an issue with its servers. Verify that you currently have permission to access their network as well.
Tips & Warnings
- Check to make sure that you have the phone line cable inserted into the "Line" jack, and not the "Telephone" jack if using a dial-up modem.
