Very short range. So short you might as well walk the wire. WLAN N without speed and frequency 5.0 GHz. Bulky and may occupy 2 ports depending on motherboard configuration. It is operational with Windows 7 SP1 drivers, although a CD is included just in case. It gives a signal and is good to have in a pinch. No Linux support out of the box :(. I'm a big Rosewill fan and love their new dual band adapter but this one was a huge mistake on their part. I have 5 of them and haven't had any luck with any of them.
