Thanks for your answer.

My answers: this is a common wifi/internet provided by a very common french provider (Free and the Freebox) with WPA key. No problem to connect other equipment to this network.

I can do that but what information do you need exactly from my network ?
So far, I saw that:
Protocole: Wi-Fi 4 (802.11n)
Security type: Personal WPA
Band: 2.4 GHz

Thanks.
