I have used my wireless network adapter since day 1. I have used many different connections as well. I have found it to be very sturdy but since mine is so old, it will not turn on occasionally. It will connect to almost any connection in range, with proper authorization, except wireless N. While at home with a cheap linksys router and cable internet, I never disconnected or lagged and downloaded anything very quickly. While at school, however, I disconnect and frequently because of the volume of users. In short, the adapter is great, its your wireless network that counts.
