AT&T recently installed their bundle of phone, internet, and tv service (known as U-verse) in my home. Their signals are carried through fiber-optic cables and they promised fast speeds. For reasons of convenience my home computer was fitted with a wireless device to connect to the new network. Below is a comparison of the download/upload speed of my home computer with the speed of my work computer which is direct-connected to the Comcast network.
U-verse wireless speed is shown in the picture above. Comcast wired speed is shown below.
When I get a chance to pull the cat-5 wires through the walls I will connect my home computers directly to the AT&T modem/router and I expect I will see higher loading speeds.
