When you experience some problems with your router, one of the basic things to do is to reboot or restart it to fix the problem.

After that, switch the router ON or plug the LAN cable back to the computer and check if the “Error 651: The modem (or other connecting devices) has reported an error” still appears on the screen.

Option #3 – Use the latest drivers for your modem
