1. Hardware reasons.

1. Since the modem error is prompted, let’s see if there is a problem with the network card. There may be some problems with driver installation. We can try a general driver or a special network card driver;

2. Remote access to the notepad file may be inconsistent with the current network and dial-up connection configuration. If communication device settings change, reconfigure them. If that still doesn't work, delete and re-establish your broadband dial-up connection.

3. Disable local connections, then shut down the computer and unplug the network card. The modem and the power supply are disconnected for 5 minutes (i.e. the network card is discharged). Then plug in the network card and power it on. If it is a desktop computer, make sure the computer is free of static electricity.

#4. If it really doesn’t work, you can only go to a computer repair shop and check the problem through professional replacement hardware testing.

2: Software reasons.

1. If the router computer cannot dial up, open the computer and enter c:\windows\system32\logfiles\wmi. Double-click wmi and it will prompt that you do not have permission to access the folder. Click Continue to obtain permission. Restart to repair.

#2. If it still doesn’t work, we delete all etl files in wmi/RtBackup and restart the computer.

##3. Control Panel->Network and Internet->Network and Sharing Center->Change Adapter Settings->right-click Local Area Connection->Properties Configuration- >Advanced tab->Internal connection speed and duplex mode->Select 10Mbps full-duplex (my home is like this, customer service told me)->OK.
