@paradadf Thanks for it ! I've already returned the dongle to Amazon but if it may help someone it is always good !
Anyway I think recompiling a driver is a bit too advanced for me ^^
@gkralicek2 Searching out something else, I found an old USB wifi dongle (BELKIN N300 Micro Wireless Adapater) and it works like a charm !
@gkralicek2 Ok I take this one from amazon.
I'll get you in touch when I'll get it.
However thanks for the time past trying to solve the problem.
@gkralicek2 ... not better after reinstalling... I will try with another usb dongle, any advice about which one to get ?
Maybe should I try reinstalling from zero the last update of the recalbox OS, is there a possibility that It will solve the problem ?
@gkralicek2 Ok. I managed to isolate the part of the recalbox.log file that matches the boot with Ethernet, I think it is OK. Here is the part of the file :

@gkralicek2 Then I get this output :

@gkralicek2 Ok so i do not have a wlan0 interface listed here is the outputof the ifconfig :

I use a 3A power supply, and I never had problems using other USB devices.
I just played for 15 minutes and never noticed any icon on the screen.
Just to be sure it doesn't come from the power supply, I tried another one, without success.
I noticed that the LED of the dongle flash for 1/10 second when I plug it.
@gkralicek2 I tried to unplugged the dongle and plug it into all the other port without sucess 
Besides,the AP SSID is visible.
Just to be sure that it don't come from the dongle itself, I plugged it on my Windows 10 PC and it works fine. But there is a LED on the dongle that flash when connected to the PC that do not flash when connected to the RPI...
@gkralicek2 I finally wrote successfully the wpa_supplicant.conf file but still not working after reboot.
So I tried launching command to debug :
wpa_supplicant -c/etc/wpa_supplicant/wpa_supplicant.conf -iwlan0 -d
Here is the output :

@gkralicek2
Thank for your help, I tried to do that but when I try writing my file with nano, I get the error message :"Error writing wpa_supplicant.conf: Read-only file system".
I tried to chmod the file but I can't, for the same reason.
How can I overpass this ?
@gkralicek2
Well, In fact, when I connected in ssh to edit the recalbox.conf I've done a copy/paste of both SSID and Key directly from the admin console of the wifi router.
So I'm pretty sure of them
@gkralicek2
it is wpa-psk(tkip) + wpa2-psk(aes).
Hi everyone,
I use recalbox on my rpi 2B since a while but I changed my home configuration and want to connect the Recalbox using Wifi.
I choose the dongle TP-LINK TL-WN823N since it is marked as supported in the compatibility list but I can't make it work.
I try to fill SSID and password in the Recalbox Interface, in the recalbox.conf using nano in ssh, but nothing works.
Here is the dmesg output when I plug the dongle :
[ 200.297992] usb 1-1.2: USB disconnect, device number 4
[ 204.373470] usb 1-1.2: new high-speed USB device number 5 using dwc_otg

Can someone have any idea ?
Thanks !
