“Error 651: The modem (or other connecting device) has reported an error”. Problem Connection of Modem Sierra 881U. Was surprised by that response. That’s how it appeared when I will start an internet connection using a AirCard Modem Sierra 881U. I have tried Uninstalling the Modem Driver, Restart the computer and reinstall but the result remains the same. Out of curiosity I tried it on my sister’s computer and found no problems.

I have tried to clean by using anti-virus for fear of the virus but the results remain the same. In addition I also perform a scan register and there is no problem but the message “Error 651: modem (or other connecting device) has reported an error” still appears. With a heavy heart I finally format and reinstall Windows XP Operating System, finally successfully and work.

Register Crash Could have happened that could not be detected by the software that I use for scanning Register? until the message “Error 651: modem (or other connecting device) has reported an error” still appear and have to reinstall the Operating System? But that’s what I did to make Sierra return Modem can connect to the Internet and no longer the message “Error 651: modem (or other connecting device) has reported an error”.
