Hi,
I am glad to assist you.
Instructions:
Please make sure the type of linksys router which you have. If your router itself has inbuilt Modem, then you can directly connect your internet cable to D-link router and follow the below steps to configure your wireless.

Things You'll Need:

* D-Link router
* Internet connection
* Ethernet cables

Set Up a D-Link Wireless Router
1. Plug one end of the Ethernet cable into the DSL modem.
2. Then plug the other end into the "WAN" port on the back of the D-Link wireless router.
4. Open your web interface and type "http://192.168.0.1" into the address bar, then hit "Enter" or "Return."
5. Use "Admin" as the username and leave the password blank when the login screen appears.
6. Click "OK." You should now see the D-Link configuration screen.
7. Contact your internet provider and ask for settings to enter into the router page.

Enable Wireless Encryption Protocol (WEP)
1.Locate the "Home" tab in the D-Link Configuration screen, and click on the "Wireless" button.
2.Use the "Open System" button beside "Authentication."
3.Select the "Enabled" button next to "WEP," and set the encryption key to "128 bit."
