The first (and will probably be the last) Encore card I bought barely worked. I got mediocre speeds, lots of connections dropped, in both Linux and Windows. It was probably just a defective one, but sorry, not gonna risk getting another one. I've used two of these: http://www.newegg.com/Product/Produc...82E16833166021 and they work great in Linux and Windows. Only $14.99 too.
