I have a Dell laptop that will not connect to the wireless Internet provided by my in-home router. I can pick up wireless from my iPad and three different iPhones, but not my laptop.
I can access internet on the laptop when plugged into the router's ethernet cord, but not through wireless. It shows me my network when I try to logon, but it is grey in color and unable to select the wireless network.
The router is an AT&T 7550 Router and the Laptop is a Dell Inspirion.
