This card will work fine if you're close to your router, in my old flat I was about 3m away and separated by a single wall. It worked great. At my next house I'm about 8m away, and there's a few brick walls in the way. It gets 2–3 bars, but speeds of about 0.2 Mbps. I ended up having to use my Macbook for wifi, and then share it with my desktop via ethernet to get proper speeds.
