Last week I went through the wifi connection tutorial and was not able to get online but I did see my router. Now I can't see anything when I open wifi config the adapter and network fields in the wpa gui are blank. I know I should use a powered hub, and I will soon. But why blank now and not before? Scan opens a scan window and does no more.
What I really want to do is use the TTL cable to run the VNC on my laptop. I don't have the IP address for the putty config window. Can I do this w/o establishing an internet connection? I only have wifi. SSID, check. I did enable SSH through the lxterminal w/ raspi-config. And I can make a serial connection, no problems. Any way around that number?
