Troubleshooting Common Wiring Issues

If you're experiencing problems with your DSL connection, incorrect wiring could be a culprit. Here are some common issues and troubleshooting tips:

No Internet Connection

• Check the wiring: Ensure the DSL modem is plugged into the correct jack. If you're using a splitter, make sure it's connected properly.

Intermittent Internet Connection

• Check for interference: Other devices, such as cordless phones or electrical appliances, can interfere with DSL signals. Try unplugging them temporarily to see if it improves the connection.
• Check the wiring diagram: Verify the wiring configuration is correct and ensure the DSL and phone lines are properly separated.

Distorted Phone Calls

• Check the wiring: Make sure the phone line is properly connected to the phone jack and the wiring configuration is accurate.
• Check for interference: Other devices, such as electrical appliances, can interfere with phone signals. Try unplugging them to see if it improves the call quality.
• Check the DSL filter: If you're using a DSL filter, ensure it's connected properly and is not faulty.
