How to Connect a Computer to a Cable Modem or Wireless Router

Modems and Routers are different.

Connecting a computer to a cable or modem, or via a wireless router is simple. However, if the router has a preset passcode, there are often difficulties involved. There are a few simple steps to check the router and/or modem to ensure they're working properly, and to make sure your computer can connect to the Internet easily.

Instructions

Setting up the Modem and Router

1. 

   Coaxial Cable Goes into Modem

   Connect the cable to the Cable Modem. The cable that comes out of the wall to connect to your television can also be connected to a cable modem if you've paid for that service. The modem has a spot in the back for the "coaxial" cable to be screwed in. There's another port for an ethernet cord (like a big phone wire) to be plugged in. This can go directly into the ethernet port on your computer, or it can be plugged into the "internet" port on the back of a router.

2. 

   Several Ports Are Good

   Use a wireless router. Unless you have just one desktop computer, using a wireless router is a good idea. It essentially splits the Internet signal into several different directions, giving the capability to still have a desktop computer hardwired into it, and sending out a wireless signal that other computers in the vicinity can pick up.

3. 

   Using the Wireless Signal

   Connect the ethernet cord from the cable modem to the wireless router. The correct port is usually set apart from the others and is often labeled "Internet." This brings the signal into the router. The router splits it into usable signals.

4. 

   Connection Established!

   Using the wireless part of the wireless router is probably the most complicated part. Log into the router by connecting to it with an ethernet cable and then going to 192.168.0.1. This takes you into the router itself so that you can edit its settings, set up passwords, and more.

Tips & Warnings

• If after following the steps above, your computer won't connect to the web, try turning all hardware off and then back on (it helps if it's all connected to one power strip). This essentially restarts everything at the same time, like rebooting the computer itself. You can also restart the computer while hardwired to the router or modem to see if it connects that way but not wirelessly. Most routers also have a "reset" button somewhere underneath to reset passwords in case you purchased the modem used.

• Cable companies also have help lines you can call if you still have problems. They might have to send a technician to your home to help you get everything set.
