@jay_s_uk It working ! I can access now to the duet web controller ! a huge thanks for that !
I have another question, The duet is pinned to my router.
But the board will be back to the workshop and there is no wifi there. I remember, the guy from Ooznest set my duet to send it own wifi.
I've plugged out the router and I can't connect the duet.
How Could I achieve this ?
@infiniteloop @jay_s_uk It works perfectly now !!!!
I have some other issues but it's with the machine haha
Thank you a lot @jay_s_uk for your help and your patience. I've learned a lot through this long slog 
Hope this will help some people as well.
Thank you all !

@jay_s_uk sorry I understood now. I will !
@jay_s_uk I've seen it before to have all those issues.
I will sound probably stupid but it's not on GitHub. Where can I get the config.g ?
@jay_s_uk yes I'm just sending M552 S1 on YAT.
what do you mean by the config ? config.g ?
@jay_s_uk I've done it and still the same problem.
I've send a M122 command and the SD card is not detected...
@jay_s_uk router is in wireless but I've realized that I did a mistake in the IP router. so I've done it again. The module is connected to access point to the IP address: 192.168.0.10 and my IPv4 address of my router is 192.168.0.14.
On the PC, nothing changed but on my Mac I've got this.
here is my sd card
@phaedrux Yes I have this app but don't know why, but never been a success when I've tried to connect the duet to the router 
@jay_s_uk I found a PC and I've download YAT and it works !!!!!!
I mean Almost !!!!!
the blue wifi led is now ON !
the duet is connected but When I tried to be on the IP address, I can't access to the duet platform. I've got this message ERR_CONNECTION_REFUSED
also I can't see the duet on the wifi network list
@jay_s_uk I've followed your advice and I've formatted the SD Card from Formatter software and it worked perfectly.
But Now I've another issue....
I can't connect the duet to the wifi to set it up.
the link that I've followed :
https://docs.duet3d.com/How_to_guides/Getting_connected/Getting_connected_to_your_Duet
And this is what I've done
I can't or maybe I don't understand how to Configure network SSID and password.
What I've missed ?
