@entozoon please don't. You can edit your first post and make it clear it's a Raspbian issue preferably leaving original text in place for reference) (please don't blank your post as it will mess the thread up). You can't delete the entire topic anyway.

@xxalphawolf420xx From the 2nd screenshot, I see that the WLAN Country hasn't been set. It shows as DFS-UNSET, while on a working system it should show:

root@pie4:/home/pi# iw reg get global country UK: DFS-ETSI (5250 - 5330 @ 80), (N/A, 20), (0 ms), DFS, AUTO-BW (5490 - 5710 @ 160), (N/A, 27), (0 ms), DFS (57000 - 66000 @ 2160), (N/A, 40), (N/A)

The other command screenshot looks like the command's been miss-typed (wlan instead of wlan0).
Check again your wpa_supplicant.conf and make sure it's correct - no extraneous characters, proper newlines, no funny quotes, un-balanced parantheses {/}. Post it here to take a look.

I had issues with Pi4 wifi too. In my case I was noticing it when sending files over Samba from W10 or using FTP, and also scraping problems. I'd get constant disconnects and transfer speeds of around 200kb/s even when it would stay working.

I found mentions online of known issues where noise from the HDMI output can disrupt the wifi signal. Every instance I saw talked about said it was only over a certain resolution (1440 I think), but I decided to try disconnecting my 5" screen anyway, which runs 800x480, and as soon as I did that the speeds went up to around 3-5MB/s and the connection stays stable.

@Donkbot said in USB wifi dongle and retropie:

Am I going to have to build the project first?

There are installation instructions (using dkms) on the project page - there's no need for a 'release'.

We don't support 3rd party images - image your sd card with the image from retropie.org.uk/download. We don't know how the sdcard you purchased was configured or pre-installed with RetroPie.

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.

@MartyH1988

First try to follow all these steps (all of them from the top!):
https://retropie.org.uk/docs/Wifi/

Then to transfer roms over the network follow these steps:
https://retropie.org.uk/docs/Transferring-Roms/#samba-shares

Make sure you place the roms in the right folders! Read the documentation. For example for the SNES:
https://retropie.org.uk/docs/Super-Nintendo-Entertainment-System/#roms

If you cant find the network share, perhaps try this way of accessing your pi through SFTP.
https://retropie.org.uk/docs/Transferring-Roms/#sftp

I've been unable to connect to the network share on my pi. For me it turned out I'm having a problem that windows 10 had certain group policies disabled that blocked the share. The fix was explained here. Though, I didnt like the idea of leaving insecure policies open, so I decided to transfer roms with SFTP. Or alternatively, using an old windows 7 laptop, which could access the share.

@BGallagherLA wondering if that is just an automatic thing with NetPlay and is just a computer player or something rather than someone actually joining? I just don't understand how someone can randomly join a game when you need the proper external IP to be able to access the game, and the exact same rom set, emulator and RetroPie version in order for it to work

Hi,
thanks, I got it working now. After checking all different settings of my router hardware and the powerline adapters, I resetted the powerline / WiFi adapter to factory defaults an reconfigured it. Strange enough, without changing anything, it works now. I guess that it was a problem with the firmware of the powerline / WiFi adapter since the web interface wasn't available on this specific adapter as well.

Thanks.

Change name of ssid was not solution.
I'm in Italy . I can connect (with WPA2-PSK) only the first time after install of retropie 4.6 on my rpi4.
After a reboot i can't connect.

With your hint i can reconnect. Finally.

NB: I see a log on startup with "FAILED to start dhcpcp on all interface" and statup is sometime slow than before (for counting time of something), but wifi works fine.
Thank you very much, PiUser239043

Hostname works but only with Ethernet
Tried without Ethernet just continues trying to connect
I usedhostname retropie

@BenMcLean said in Why the hell doesn't RetroPie come with an On-Screen Keyboard?:

We've known how to do this for a decade and a half at least.

I don't. Who is this illustrious "we" you're talking about?

thank a lot for you help
problem solved

@mitu The Bluetooth is down. I could not get my controllers to connect. They would with the usb cable, but not Bluetooth. I think the module might be done.

@SolemnSpirit Thanks that helped!, the moment i remove the key_mgmt, i was able to connect to the wireless! :D i appreciate you posting this!

A Raspberry Pi Zero doesn't have a WiFi NIC, so not being able to connect to WiFi is the expected result.
Only Pi Zero W and Pi Zero WH have WiFi NICs.
