CenturyLink offers DSL or Digital Subscriber Line. A red light on the modem is indicative of a connectivity problem or a problem in the router. Restarting both your CenturyLink modem and router should resolve the red DSL light issue. Try to reset if the problem continues. Contact CenturyLink support if it hasn’t disappeared by then.
Rebooting the Router
Restarting the router and modem is the safest option you can try. How to do it:
Disconnect the router’s power supply. Wait for about a minute or two. Reconnect the router’s power cable. Your problem has been resolved if the light turns green.
Rebooting the Modem
If you’ve determined that the router isn’t the concern, assess the modem. Try restarting to see if that resolves the problem.
Remove the power cord for the modem from the wall outlet. Wait for about a minute. Reconnect the power cord. Watch for the modem to turn on completely again. Your problem is resolved if you can now access the internet.
Reset the Modem
A setting modification that you made or that happened automatically can cause problems, so rebooting your modem can resolve them.
To reset a Centurylink router,
On a networked device, launch the browser. In the address box, enter “http://192. 168. 0. 1” without the quotations. Access the modem’s settings page by logging in. The admin login information can be found on a sticker either on the modem’s sides or underside it. “Restore Defaults” can be found under the “Utilities” selection. Choose “Restore Modem to Factory Default State”. Let the modem do its factory reset by waiting a short while. The LED will turn orange once completed. Switch on the modem.
Update Firmware
Firmware used by routers occasionally receives upgrades to address serious problems. Although firmware updates for routers are not common, installing the new firmware and having your router updated is important since it’s possible that the issue that’s generating the red light was resolved with such a firmware update.
To update your router’s firmware:
Launch a web browser and enter “http://192. 168. 0. 1” in the address bar without quotation marks. Use your administrator username and password to access the modem’s settings panel. “Upgrade Firmware” can be found by selecting the Utilities icon. Examine the “Upgrade Status” section.
To continue the update, go to step 5 if it reads Upgrade Firmware. There is no update for your modem if it reads “Firmware up to date” or “N/A. ”
To download the file to your computer, choose “Download. ” Select “Browse” once it has been saved to the location of your choice. Click “Open” after finding the file you just downloaded. The modem will start a firmware update that can take up to three minutes after you click “Upgrade Firmware. ” After installation, the modem will reboot. Open a website to check your connection after waiting for all the modem’s lights to turn back on.
Inspect Ethernet Cable
One of the system’s failure spots could be the ethernet link between the modem and router. Verify the connecting ends for the small plastic clip to make sure it is not bent or missing. The connector is secured by those clips. You’re advised to replace the cables if they are damaged.
Check Login Information
Incorrectly entering your internet login information can potentially result in a red DSL light issue. Log in to the modem to verify your login information. After that, get in touch with CenturyLink to verify your credentials and compare them to the data entered on the website. To avoid having to test for this again if any other errors arise after you reboot, make sure you provide the login information accurately.
Conclusion
The majority of internet connection problems are rather simple to resolve, and we’ve already shown you how to resolve the red DSL light on your router. Sadly, most routers that ISPs provide are bog-standard and only have fundamental features. If you want to future-proof your home, you can consider purchasing a mesh router system.
