The information on AMAZON did not make it clear to us that the computer did not have build in WiFi, nor did information that came with the computer indicate that a USB device needed to be used for WiFi.  After hours of trying to determine the problem, we found out that the USB sent with the computer was for WIFi.  That USB stopped working after a week or so and now for WiFI we have to string an unsightly Ethernet cable from upstairs through the living rook to the router.
