I just finished building a box. Due to things outside of my control I can't hardwire it to the internet. So I bought a wireless pci-express card. This one to be exact: Encore n150. I run iwconfig and get a description of the wireless card including that it's in managed mode and power management is off. So it seems that the card is up. However when I run iwlist wlan0 scan. It returns no networks. However I know for a fact there are networks because I'm on the wireless in my house right now on a PC asking this question.
So my official question, is what could cause the card to be recognized but then not even see a wireless network (there are others in proximity and it's not seeing those others). Is this a linux issue, or could the card be DOA? If this is a drivers issue, assuming I track them down how do I then install them without internet? Thanks for the help. I'm kind of a noob here.
