Error 651 Modem Errors and Issues

Error 651 is an error code that essentially translates to the modem reporting that there is an error. Users will see this when the modem is attempting to connect to a network or the internet, but is unable to do so. There are many causes for this issue, starting with the central piece of hardware involved in the equation, the modem. If you received the error message whilst the modem was attempting to connect, it may be that the USB cable was unplugged during this process.

First and foremost, the obvious and often overlooked inspections should take place to rule out any simple solutions before delving deeper into the possibilities. Ensure the modem is turned on and installed correctly, the cables are in good condition and plugged into the correct ports. Performing a power cycle may work in some cases. To do this, after shutting down your computer, turn off the router, wait at least a minute, then turn off the modem. Disconnect all network cables and reconnect them after a minute. Finally, power up the modem, wait a minute, then turn on the router.

Next check to be sure the modem is enabled and that Windows is in fact using the correct networking device. Check to see if some other program on the computer such as a fax is using the modem already as that can hinder connectivity. Sometimes the modem software may become corrupted, so try uninstalling and reinstalling the modem software. Also check to see if the latest drivers for the modem are installed on the computer. Also, the currently installed drivers may be corrupted so you may want to remove all networking drivers and reinstalling them. If you have more than one modem installed, perhaps a dial-up modem, try disabling the unused modem, this may help.

Last but not least, try removing and reinstalling the modem or networking device hardware you are using to connect.
