How to Connect From Wireless to Landlineby Greyson Ferguson
If you access the Internet via a wireless connection in your home, you have a DSL or cable Internet line coming into the house with a wireless router connected to it. If you want to switch from wireless to the landline you can do so without much effort by connecting your computer to the DSL or cable modem your wireless router uses to access the Internet.
Connect the Ethernet cable into one of the numbered ports in the back of the DSL or cable modem. More than likely a cable is running out of the first port into the wireless router. There is no need to unplug the wireless router. Simply plug the Ethernet cable into the second numbered port.
Plug the other end of the Ethernet cable into the Ethernet port on your computer. A light next to the port illuminates when the connection is secure.
Right-click the wireless Internet icon in the lower right corner of your desktop and select "Disable" from the pull-up menu. This keeps your computer from attempting to use the wireless signal instead of the landline.
Launch the Internet browser on your computer. The computer now accesses the Internet via the landline. There is no need to adjust any of your routers, modem or the computer itself.
