bobbobg,

What ISP are you using? Do you have a wireless router?

The Inspiron 580 is a desktop. Do you have a wireless card or a USB adapter to connect to the wireless router?

I use Comcast cable for Internet, phone, and TV.  I do not have a wireless router, but will buy one if I need it, though I'm not sure just what router to get.  I don't know if I have a wireless card.  I have USB available.  What am I missing?

The desktop can plug in to the Comcast router using an ethernet cable. Most computers have an ethernet adapter. It looks like a phone cord adapter but bigger. If your computer does not have one, here are some options.

You can get an Ethernet card and install it.

You can get a wireless card for your computer. It will have antennas in the back of the computer. To use this, you'll also need a wireless router. The wireless router will need to be setup. Here are some easy to follow the instructions. You won't need to uninstall the adapter. Setting up/Troubleshooting a Wireless Network
