Bonjour à tous,
Je suis en train de remettre à flot pour ma fille une vieille tour:
ACER Aspire 1600
Proc: Genuine Intel® CPU 2140 @ 1.60GHz × 2
carte graphique: llvmpipe (LLVM 8.0, 128 bits)
sous Ubuntu 18.04.3 LTS.
Je cherche à connecter une clé wifi Boulanger Nano 300. J'ai passé de longues heures sur la partie wifi du forum. Les divers drivers installés ( rtl 8192eu; rtl 8812au ou 8192du) arrivent à me donner le nom de ma box mais n'arrivent pas à une connexion du PC. J'ai passé ma box en wifi wpa2.
Rien de probant. Merci d'avance pour vos suggestions. Peut être serait-il plus judicieux de passer à une carte wifi PCI?
Ci joint le résultat du script wifichek:
