      Hi, I'd like to preface this by saying I am completely new to the word of RPi, and this is my first attempt at using RetroPie

      I'm trying to connect my RPi 3 to the internet, but I've noticed in the sudo ifconfig readout that I amd not showing an IPv4 address, only IPv6.

      I also noitced that none of my SSIDs are showing up when I try to connect to the network using retropie. A few showed up yesterday, but none of them were mine. I've looked on a dozen or so pages, but can't seem to find an answer

      My setup looks like this
      Pi Model or other hardware: RPi 3
      Power Supply used: DC5v 2500mA
      RetroPie Version Used: 4.3
      Built From: Pre made SD Image on RetroPie website
      USB Devices connected: HP Keyboard and Controller
      Controller used: Retro-Bit SNES style
      Error messages received: None

      Any help would be appreciated

      Also, I'm not totally sure how to export the config file so I can add it here, so if anyone can help me out with that I'd be thankful

        @rod419 So your wlan0 doesn’t look like this?

        wlan0     Link encap:Ethernet  HWaddr b8:27:eb:xx:xx:xx  
                  inet addr:192.168.1.100  Bcast:192.168.1.255  Mask:255.255.255.0

        Run iwconfig in the terminal. What does it say?

          @jonnykesh Thanks for the quick response.

          No mine skips the inet addr: line and goes right to inet6 addr:

          How would I export a screen cap like the one you posted? I'm sure it would help in troubleshooting this

            @rod419 That's just a copy and paste from the terminal. I SSH into my Pi from my PC.

                @jonnykesh My iwconfig shows no wireless extensions on wlan0
                ESSID:off/any
                Power Management: on (could this be it? I noticed that on wlan1 it is set to off)

                However, when I plug a wireless adapter in it picks up the SSID and the iwconfig shows all the pertinent information on wlan1

                Also I can't seem to SSH from my PC, regardless of what IP I use.

                  @rod419 the power management is not the issue. Have a read of this and check out a few of the posted links. This will get you started troubleshooting. https://raspberrypi.stackexchange.com/questions/51680/raspberry-pi-3-no-wlan0-listed-no-wireless

                    Well, if there is no network configured it's not possible to use SSH to the PI, unless you have a wired connection. If you have one, then you first need to enable SSH, since it's disabled by default - use the raspi-config script (see here).

                    Remember that the PI 3 only connects over 2.4Ghz, so if your access point only works in 5Ghz, then you'll not see the SSID. This happened to me the other day. Maybe the external wireless adapter has 5Ghz support and that's why it's able to connect.

                    Here is a Wireless configuration guide for the PI - including command to scan for SSIDs and configure the wireless from command line.
