The CD that comes with the unit does not have drivers for Vista or Windows 7. You have to go to the Engenius website to find them. Downloading and installing has been a huge hassle. I still don't have it working. And the Users Manual, both on the CD and on the website, has not been updated to include Vista or Windows 7. The installation/operating instructions are totally unapplicable for Vista/7 users. Also, the cable connector to the Engenius port is very delicate and makes only intermittent contact. If you're running Vista or Windows 7, do not buy this product.
