When I had the Pi on my wired network, I could see the pi in my windows explorer, drop roms in their appropriate folders and life was good. I needed to cut the cord and move the pi so I got an edimax wifi dongle and it wasn’t too difficult to get working. However, now when I go to my windows PC I can’t detect the pi. I’m using WPA+PSK/WPA2+PSK encryption on my router. I’ve configured the wpa_gui to use wpa and I had an it connected to my network but it wasn’t visible on my PC. I then configured the wpa_gui to wpa2 and in again connected fine was visible after a reboot but I could expand the folder on my PC. If I run it upstairs and plug it into the router, everything works. Advice?
