Sometimes, there may be problem of disconnection even if your user name and password are both correct. Thee may be several reasons of such disconnection. Some of the typical reasons are:
Your modem is not properly installed and is having problem holding connection.
Your telephone line has too many connection points or branches and the quality of such interconnections are not very good.
Your telephone line is a pair gain (PG) line. Normally, due to the nature of PG lines, the internet connection using them is usually very slow compared to normal lines. Sometimes, however, connection establishment itself may not be successful.
In many occasions, disconnection may occur due to improper settings of the modem speed. Reducing the speed of the modem may be a solution of such problems.
Another cause of undesirable performance and problems of disconnections etc can be underperformance by the related features of the computer or some problem with these features. The main features of computer that are relevant here are the Dial-up Adaptor and TCP-IP protocol. The coming sections of this page discuss these features and their troubleshoot in more detail.
For proper results, you have to change the modem speed at two locations. First at the dialup account and second at the modem item of the control panel.
To change speed of modem on the dial-up account, go to My Computer -> Dial-up networking and right click on the dial-up account. Here it is ‘NTCnet’. Click on Properties. (Fig. 1)

The properties window of Fig. 2 will show up. Click on Configure on the General tab.

On the new window that comes up, select the new speed of the modem at the bottom of the window. (Fig. 3). You can select lower values if the connections are not successful at higher values.

To change modem speed from the Control Panel, open Control Panel and double-click on Modem icon. (Fig. 4)
figure 4
A window containing the list of modems installed will appear. Select the name of the modem installed on your computer and click on Properties. (Fig. 5)

On the General tab select appropriate speed (Fig. 3) and press OK. Press OK again to return to Control Panel.
Checking configuration of dial-up services in the computer
Sometimes, refreshing the dial-up services (or reinstalling them) may be a good solution of problems in getting connected such as disconnection, no data transfer over the connection and so on.
There are two components that need to operate correctly to have a desirable dial-up performance. These are:
Dial-up adapter
TCP / IP protocol
To check and set the properties of the dial-up and related services in the computer, proceed as follows:
Open the Control Panel and double click on Network icon. (Fig. 6)
figure 6
A new window with all the network services installed in your computer will appear.
If you just want to check the properties, just highlight the dial-up adaptor and TCP/IP and click on properties. (Fig. 7)
figure 7
On properties of TCP/IP -> Dial-up Adaptor, set properties as shown in Fig. 8 and Fig. 9

figure 9
You can also check the properties of Dial-up Adaptor. (Fig. 10)
Refreshing TCP/IP protocol and Dial-up adaptor in the computer
To refresh the TCP/IP protocol and Dial-up adapter, proceed as follows:
First, to remove existing Dial-up Adapter and TCP/IP, on Fig. 7, select these one by one and click remove.
Now, click on Add to get Fig. 11.
figure 11
Select Adapter and click on Add. You get Fig. 12
figure 12
Select Microsoft on the left and then select Dial-up Adapter on the right. Press OK. Dial-up Adapter will now be added.
For TCP / IP, select Protocol on Fig. 11 and click Add. You get Fig. 13.
figure 13
Select Microsoft on the left list and select TCP/IP on the right. Press OK. TCP/IP will now be added.
Click OK once more. Now Windows will take some time building the driver information database and then your computer will be restarted before the changes take effect.
