Impossible d'installer les pilotes WiFi pour Broadcom AP6255
j'essaye de configurer le WiFi sur mon mini PC Beelink BT3 PRO qui a un Broadcom AP6255. J'ai essayé plusieurs des solutions proposées en ligne mais sans succès. L'interface ne s'affiche tout simplement pas. C'est le résultat de l'info sans fil.

J'ai contacté le support produit Beelink et ils m'ont envoyé des pilotes, mais je ne sais pas comment l'installer.
Les pilotes semblent être une copie de ce dépôt https://github.com/linux-rockchip/linux-rockchip/tree/mirror/stable-3.0/drivers/net/wireless/rkwifi/bcmdhd
Quelqu'un peut-il me donner des indices?
Votre appareil est presque certainement le suivant:
alias: sdio:c*v02D0d4345*
Cela provient du champ d'alias du pilote brcmfmac qui se charge au démarrage en fonction de votre dmesg. Nous obtenons l'indice de votre dmesg:
brcmfmac: brcmf_fw_map_chip_to_name: using brcm/brcmfmac43455-sdio.bin for chip 0x004345(17221) rev 0x000006
Le seul alias "4345" est celui que j'ai cité ci-dessus.
Diverses sources suggèrent, comme vous l'avez indiqué dans votre question, que le pilote bcmdhd est préféré. Cependant, aucune version récente du pilote ne peut être trouvée pour compiler et essayer. La dernière mise à jour du code auquel vous avez fait référence a été mise à jour il y a six ans. Il ne se compilera sur aucun noyau récent.
Enfin, les rapports Wikidevi généralement fiables: https://wikidevi.com/wiki/Talk:Linux_Wi-Fi_device_entries#02d0_-_Broadcom
02d0: 4345 - BCM4345 (ancien ver BCM43455) - ID SDIO non pris en charge: SD\VID_02D0 & PID_4345
En conclusion, bien que brcmfmac charge et charge le firmware, il ne pilote pas l'appareil. Je regrette d'être d'accord; l'appareil n'est pas pris en charge.
[~ # ~] note de bas de page [~ # ~] : J'ai inclus mes notes de recherche ici car j'espère que cela aidera les autres qui recherchent.
Dans le bureau ubuntu-live , l'installation du Wi-Fi a été activée sans aucun problème, après l'installation du serveur Ubuntu 18, le Wi-Fi n'a pas fonctionné.
La solution a été trouvée sur le lien ci-dessous et ses instructions pour activer le Wi-Fi.
https://medium.com/home-wireless/run-headless-ubuntu-on-an-atom-z8350-pc-48df5645bba
Transposez également la solution ici:
Créez le fichier /lib/firmware/brcm/brcmfmac43455-sdio.txt et redémarrez le système. L'interface Wi-Fi wlan0 peut maintenant être configuré avec netplan, systemd ou /etc/network/interfaces style.

Le fichier de définition NVRAM manquant dépend de la carte. Vous pouvez voir que le firmware kernel inclut ce fichier pour certaines cartes. Nous devons envoyer des demandes de tirage pour prendre en charge d'autres conseils. Notez que BCM43455 est une version plus récente de BCM4345, également connue sous le nom d'AP6255; Il se trouve que j'ai l'ancienne version et qu'elle est prise en charge par le pilote brcmfmac.
Sur un mini PC Wintel (AMI, T3 MRD, Atom x5-Z8350 [CherryTrail]) exécutant Windows 10, le fichier se trouve dans C:\Windows\System32\drivers\4345r6nvram.txt (fichier contenu s'est avéré être identique à la réponse de Sascha) et peut être copié sur Linux, puis faites:
Sudo cp 4345r6nvram.txt /lib/firmware/brcm/
cd /lib/firmware/brcm/
ln -s 4345r6nvram.txt brcmfmac43455-sdio.txt
Sudo modprobe -r brcmfmac
Sudo modprobe brcmfmac
