Realtek rtl8821ce non détectée / pas de pilote installé [Résolu]

Bonjour à tous,

J'ai un nouvel ordi Asus, freedos, sur lequel j'ai installé la dernière version d'Ubuntu Focal. J'ai essayé tout ce que j'ai pu trouvé comme tuto mais rien n'y fait:  impossible de connecter le wifi.

Ce pc n'a pas de port ethernet et ne peut pas être connecté à internet autrement qu'en wifi.

Ci-dessous, le résultat des différentes lignes de commamdes du post "à lire avant de poster"

Je ne sais plus quoi faire ... merci d'avance de votre aide

jrm@jrm-ASUS:~$ lspci -k nn | grep -A 3 -i net
Usage: lspci [<switches>]

Basic display modes:
-mm		Produce machine-readable output (single -m for an obsolete format)
-t		Show bus tree

Display options:
-v		Be verbose (-vv or -vvv for higher verbosity)
-k		Show kernel drivers handling each device
-x		Show hex-dump of the standard part of the config space
-xxx		Show hex-dump of the whole config space (dangerous; root only)
-xxxx		Show hex-dump of the 4096-byte extended config space (root only)
-b		Bus-centric view (addresses and IRQ's as seen by the bus)
-D		Always show domain numbers
-P		Display bridge path in addition to bus and device number
-PP		Display bus path in addition to bus and device number

Resolving of device ID's to names:
-n		Show numeric ID's
-nn		Show both textual and numeric ID's (names & numbers)
-q		Query the PCI ID database for unknown ID's via DNS
-qq		As above, but re-query locally cached entries
-Q		Query the PCI ID database for all ID's via DNS

Selection of devices:
-s [[[[<domain>]:]<bus>]:][<slot>][.[<func>]]	Show only devices in selected slots
-d [<vendor>]:[<device>][:<class>]		Show only devices with specified ID's

Other options:
-i <file>	Use specified ID database instead of /usr/share/misc/pci.ids.gz
-p <file>	Look up kernel modules in a given file instead of default modules.pcimap
-M		Enable `bus mapping' mode (dangerous; root only)

PCI access options:
-A <method>	Use the specified PCI access method (see `-A help' for a list)
-O <par>=<val>	Set PCI access parameter (see `-O help' for a list)
-G		Enable PCI access debugging
-H <mode>	Use direct hardware access (<mode> = 1 or 2)
-F <file>	Read PCI configuration dump from a given file

Re : Realtek rtl8821ce non détectée / pas de pilote installé [Résolu]

Bonjour,

Pas de smartphone ?

Voir > Connexion de secours - partage de connexion avec un smartphone

sudo apt update

sudo apt install rtl8821ce-dkms

Voir aussi le § 2 et le début du § 3 > [Tuto] Pas de Wi-fi ? Eléments importants à vérifier pour désactiver le secure-boot.
