Connecting a laptop to a cable modem is not that different from connecting it to a desktop computer. So, if you opted to purchase a laptop instead of a desktop, you will be able to set up your own home network just like you would on a desktop. Always read the manual that comes with the modem first, and ensure you have all the items you need to connect the modem to the laptop. You will be surfing the web in no time.
Boot up the computer. Do not connect any wires yet.
Install the software that came with the modem onto your laptop.
Connect the coaxial cable from the wall to the cable outlet on the back of the modem. Spin the metal piece on the end of the cable to tighten it to the modem.
Connect the power cord to the wall and the modem. Ensure the modem lights up after plugging in the power cable.
Connect the modem to your laptop using either a USB cable or an Ethernet cord.
Configure the modem. Go to the "Network Connections" on your Windows laptop and select to view the "Properties" of the shown LAN connection. Select "Internet Protocol" and click "Properties." Select to "Obtain an IP address automatically." For a MacBook, the network settings can be found in the "Network" pane of the "System Preferences;" configure the Internet settings in the "Setup Assistant."
Consult the modem's user guide to troubleshoot any connection problems.
