We have at+t uverse. The box at+t gave us has built in wireless, but its got a password, WPA. But I have a Wireless router in my room as a router for my computer and my xbox to share the internet from the uverse tv box in my room. (the internet and tv goes over the coax and these boxes pick it up, and have a ethernet port on the back for your computer) Today I looked at the DHCP list in the belkin's router setup. (see picture, my computer is amd386dx) I just added a WPA key to it and even turned off the wifi, and the wireless light is turned off on the router to confirm it. They still show up on the list when I hit refresh. Does it just take a while?
