It is a Linksys AE3000 card which is capable of doing N900 but the router type is not listed, if it not a N900 capable router then you will only ever see between 50 to 150. If your router can do AC then get a new adapter, one specifically designed for AC. What router do you have?
OK, now I understand where you're coming from. Newer 802.11g products are advertised/described as "dual band" and do indeed go to both frequencies. Older devices do not. People need to be aware of what they've got, or take the time to dig into device info for the NIC or router to see what's what. "Nuff said.
