I’m in Unit 2, Module 4 “Searching for the Pi on a network”.  I’m using a Pi 1 (cause I had it) and have Jessie Lite installed on my Flash Card.  I’m attempting to connect to my Network using an Edimax N150 Wi-Fi Nano USB Adapter.  I work and play in my office downstairs and connect my desktop to the Internet through a WiFi router with a different USB Wirless adapter so I know the signal is there.  When I look on Angry IP scanner I see several addresses active (blue), but none is labeled Raspberry Pi as the example shows.  I also noted that the Wi-Fi Nano USB Adapter came with a driver disk, but – obviously – it’s hard to insert the little CD in the Pi.  I could go upstairs and plug the Pi in with an Ethernet cable, but then all my instructions are downstairs, and I want the flexibility the Wi-Fi offers.  So I’m stumped.  I think it is a driver issue, but I can’t load drivers I can’t see.  The Wi-Fi Nano is touted as working well with R Pi, but lots of questions and answers on the Amazon purchase page talk about loading drivers.  Can anyone help?
