Hello, I recently married and want to move my desktop to my wife's home where we've chosen to live. My tablet just finds the wireless router and allow me to connect. My old, now defunct, laptop did the same. My old desktop was connected via wire to my internet connection at my old plsce. What do I need to add to the computer to have it connect wirelessly like the tablet and laptop. I do not need to share info. Just be able to hit the internet from the desktop wirelessly. Desktop is a PC by Dell bought two years ago. Thanks for any help.
