On obtient tous les pilotes lors de l’installation si on choisit l’ISO :
– firmware Debian 10 DVD1 (si on n’a que du WI-FI)
– firmware Debian 10 netinst (à condition de brancher un cable Ethernet)
- Choisir une distribution complète : exemple Debian qui possède tous les dépots des firmware !!! Exemple : netinst avec cable Ethernet
- Voici les commandes à saisir pour installer le bon pilote : histoire d’une galère !!! .. avec la solution en 4 lignes à la fin …
La solution a été trouvée grâce au site : debian-facile.org

Enfin la solution : Le firmware manquant étaitfirmware-realtek (RTL..)
1) Visionner les erreur au démarrage :dmesg | grep firmware
2) Lister les firmwares déjà installés :dpkg -l | grep firmware
3) Installer le firmware manquant :apt-get install firmware-realt*
4) Redémarrer : sudo reboot
Tant que KO installer un autre firmware… etc...
OK : le 10 avril 2020 !
