@quasimaddboy neither. They mean the script itself. From the main menu (not the "manage packages" submenu), choose Update (updates the setup script and all installed packages) or Update RetroPie-Setup script (does what it says on the tin, updates just the setup script but not the underlying packages. The first one takes a lot longer.)

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.

It seems to download fine for me. We've had a few complaints over time with similar symptoms, it's usually something ISP related. Try downloading from another location or try a torrent download.

@ceruleansoul Here's how I successfully installed Retropie:

Made sure I have a formatted SD card to FAT32. Follow the download instruction and installation for P2/P3 from this site:

Yeah, I had already checked my IP address and it hasn't changed.

I did manage to connect though. I rebooted my PC, router, and gigabit switch and somewhere in there everything corrected itself. So I'm all set now, thanks!

@Goose You didn't word anything "wrong" You just haven't supplied any, or at least, very much relevant info. This is a technical forum for users of the software, not the "psychic hotline". Try again.
