What about Win7 system modem errors?
The workaround is as follows:
1, the first need to check the power of each device and connectors are not plugged in.
2. Remote access Memo book files and current network and dial-up connections configurations may be inconsistent if you change your communication device, make sure that you reconfigure network and dial-up connections. If the error persists, you can delete and recreate network and dial-up connections.
3, Win7 error code 651, routing can not be tried on the dial: Open WINDOWSSYSTEM32LOGFILESWMI, double hit open WMI and then open the inside of the rtbackup will prompt you need administrator rights to continue to reboot, you can repair.
4, no words to the WMI suffix for the ETL file deletion including Rtbackup in the restart.
5. If none of the above is used then try, disable the local connection-shutdown-check all the cat plugs and unplug-unplug the Cat Power plug-wait 2 minutes before plugging in the plug-boot.
6, the last move first from other Internet-connected systems in the machine copy the following file C:windowssystem32driversraspppoe.sys to replace the file in your computer.
7, in the local connection properties of an Internet Protocol version 4 (TCP/IPV4), use the following IP address inside input: 192.168.1.23, subnet mask: 255.255.255.0 (netcom Mobile do not know).
