Tried this in Windows XP, immediate installation and it found a WiFi hotspot from a business at least 600 metres away as well as our own router. Installed it with Fedora Linux with no problems and it should work with any distribution using a reasonably up to date Linux kernel. Performance seems OK and range not an issue in a normal (!) house. What you can't easily do unless your Linux skills are a lot better than mine is install Linux with a basic installation disc and download the rest of the distribution wirelessly, you need a more complete installation set (typically 3 CDs). This is not a problem with the product which gets 5 stars all round, the point is that the Ralink drivers are not on the basic installation discs. As others have mentioned the antenna is not as illustrated, which suits us well.
