Connect Retroflag GPi (Raspberry Pi Zero W) to WPA2 Enterprise

oscarw

Hi!

I just got my retroflag gpi case working and set up. I have one small problem though. I can't connect my Pi to my WPA2-Enterprise network. I've tried a bunch of settings in wpa_supplicant.conf but can't get it to work.

Pi Model or other hardware: Raspberry Pi Zero W & Retroflag GPi Case
Power Supply used: Retroflag GPi's inbuilt.
RetroPie Version Used: 4.6.1
Built From: https://github.com/RetroPie/RetroPie-Setup/releases/download/4.6/retropie-buster-4.6-rpi1_zero.img.gz
USB Devices connected: Retroflag GPi
Controller used: Retroflag GPi
Error messages received:
Can't see any error messages. Don't know where they appear. It just says IP-address Unkown in show ip.
Guide used: Several on Google. This one among others: https://gist.github.com/elec3647/1e223c02ef2a9a3f836db7984011b53b.
This one for documentation: https://w1.fi/cgit/hostap/plain/wpa_supplicant/wpa_supplicant.conf
File: /etc/wpa_supplicant/wpa_supplicant.conf
Attachment of config files: (wpa_supplicant.conf)

No one? Seems like it should be a quite generic raspberry pi problem?

@oscarw I haven't seen any posts here from someone using WPA2-Enterprise for their Wifi, so the lack of advice/reaction is normal.
You should check out the RaspberryPi forums for similar problems - or maybe ask the administrators of the WiFI network for the settings.

Yeah, probably, it's not that common with enterprise networks I guess. Thank you for making that clear though.

I actually solved it just now though.

For anyone wondering I managed to connect to the network on another machine (Ubuntu) and used Network Manager. I then checked the log (according to this link) with the command:

journalctl -u NetworkManager

This gave me this config for wpa_supplicant.conf:


country=SE
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1

ap_scan=1

network={
  ssid="Wifi-Name"
  scan_ssid=1
  bgscan="simple:30:-65:300"
  key_mgmt=WPA-EAP WPA-EAP-SHA256
  password="password"
  eap=PEAP
  fragment_size=1266
  phase2="auth=MSCHAPV2"
  identity="username"
  proactive_key_caching=1
}

This might not work for everyone else since the configs are always different for every network. So be sure to do the same steps as I did if you can't get it to work.

So glad I finally got this, haha.
