Have been following a guide to installing Raspian Lite and then a desktop, etc. I have installed Raspian Lite and my Pi boots up. I have it connected to my TV via HDMI. I can log in but when I try to install the desktop manager I get errors that it can't resolve the raspberrypi web site. I finally figured I wasn't connecting to the internet. I went into raspi-config and entered my wifi network information but still when I reboot I don't think it's connecting. Can anyone help? Trying to do this all from a command prompt. I also checked my SD card on another computer and the wpa-supplicant file is there with my network name and password. Also the country code. Thanks alot.
