Retropie 3.7 - WiFi network not listed

DigitalPimp

Hi All,

I've just conducted a clean install of Retropie 3.7 on my Pi3 and found that no network access points are listed in the configuration tool. All that is shown when I try and connect to a network is "0" which is blank, and "H Hidden ESSID", when selecting "0" it makes a cursor appear at the lower left of the screen and eventually drops back to another screen saying "Unable to connect to network".

My network is not hidden and showed up fine in Retropie 3.6, is there a step I'm missing to get it working using the Pi3's internal WiFi?

Thanks in advance.

Maybe your wifi network is on channel 12 or 13.
Go to the raspi-config tool -> Internationalization Options -> Set Wi-Fi country, and select your country. Then try again and see if your wi-fi appears.

Thanks for the reply Rascas, regrettably setting the country to "GB" didn't yield any results - although I've never thought to define that before, so a positive for learning something new.

Having tinkered a little more it seems I can get it to work, but only through manually defining the network in the /etc/wpa_supplicant/wpa_supplicant.conf file. I guess there may be a bug in RetroPie 3.7, but I'm surprised no one else seems to have come across this.

I am not aware of any bug in the retropie's wifi tool, but sometimes, I have to do multiple scans for my wi-fi network to appear (there are lots of them near my house).
You can get more details of the wifi networks, like signal strenght, etc, by running some commands in terminal, for example:

sudo iwlist wlan0 scan

I've just tried that and it does indeed find the my AP via the terminal, popping back in to Retro Setup I can also see the AP there too listed against "0". Unfortunately being my luck it tries to connect and pops up with the old "Unable to connect to network" window and upon closing returns to the list of AP's with the name having vanished against "0".

I'm having this same issue. I also tried the wifi globalization setting with no luck.

Found this post as well with the same problem.

Please send me privately the contents of output.txt when running "iwlist wlan0 scan >output.txt" to buzz [at] exotica.org.uk - it's possible the code in our tool is not parsing the output correctly in your case (please let me know which is your network also)

Did anything come of this? I am experiencing the same issue.

No-one has sent me the information I have requested in the post above which I will need to debug/fix it.

I tried to do it myself, and this is the result
"wlan0 Interface doesn't support scanning."

wlan0 isn't even showing up as a usable interface

NickOban

Sorry for the late response. I get this message as well.
"wlan0 Interface doesn't support scanning."

hmm. I'm sure it works on my RPI3. Are you running from the latest RetroPie image ?

NickOban

I just noticed that the 3.8 image is available. I will flash that and give it a go. I'll report back. (I was using 3.7 when reporting to this post initially)
EDIT:
I get the same issue with 3.8 :(

To add to this discussion - I am having a similar on 3 different Raspberry Pi Zeroes - 1 has RetroPie 3.8 and the other 2 have 3.7. The first time I power on the RPi and attempt to connect it to a new network it will show all of the available networks - I select my network, enter the WPA2 password and it fails to connect. If I try to connect to a network again, no networks will be listed. I figured out that if I reboot the RPi after the initial failure the WiFi DOES connect using the saved credentials after restart.

Had the exact same issues.
Tried switching my keyboard settings. Tried the WiFikey.txt file. Tried switching to a higher power power supply. All to no avail.
Also flashed raspbian to my 'Zero W'... Same problems "no network adapters found". What started to ring bells was that also the Bluetooth adapter wasn't found.
