Hi NJ gupta,
Thank you for writing to Microsoft Community Forums.
We would need some information.
Which version of Windows you have installed?
A dial up connection uses a standard phone line and analog modem to access the Internet. Dial up connection is the least expensive way to access the Internet, but it also slowest connection.
I suggest you to try the following methods and check:
Method1: Create New Dial-Up Connection.
• At the bottom right hand corner choose your connection from WI-fi.
• Right click on it, where it will show you an option Troubleshoot problem and open Network and sharing center.
• New page will open after pressing network and sharing center, you also can directly reach to this page using by typing this link to your THIS PC Window Control Panel\All Control Panel Items\Network and Sharing Center.
• To configure a Dial-Up connections in Windows 10, click on setup a new connection or network to setup a broadband, dial-up, VPN, connection, or setup a access point and router
• It will give you’re a new options, Choose a connection option, under this multiple setting available but you have to click on, Connect to the Internet, to setup a broadband and dial-up connection to the internet.
• Click on next button, where it will give you two option if you already connected to the internet, Browser the internet now and setup a new connection anyway. Click on next button.
• New page will open where it will shows option, how do you want to connect, choose Broadband (PPPoE)
• Come to next page by clicking on next button, where you will get options to type Username, password, and Connection name, above two thing username and password will provided by ISP.
