As soon as I enter my WPS code, the 2620 Printer is OFFline.

As soon as I enter my WPS code, the 2620 Printer is OFFline.

Installation of the driver works smooth until that fatal event when the drivers ask for the WPS code. When entered the WPS code printed by the 2620, nothing abnormal happens. And the printer sets itself offline. 
This is a surprise as during the installation, the 2620 printer is recognised and set its WIFI connexion with the computer smoothly.
 
Problem comes either from W10 (I disabled the FIREWALL)
From the router  TECHNICOLOR TG799VN V2 (no idea here)
From the Driver which connect both W10 and the 2620 on two different network ?


This problem is being going for a year and half now. Many tries attempted with the HPDOCTOR and different Drivers. 
The printer wifi light is BLUE, constant lighting  so it sees the connexion in the router .

Hi,

Please press and hold the Wireless and Information buttons till the power light starts blinking, the printer will print 3 or 4 pages.

Please include a picture of the last page, the one with the title "Wireless Printer Test Report".
