Bonjour,
Je suis novice sur Ubuntu et je viens récemment d'acheter un PC sur lequel j'ai installé Ubuntu 20.04 en dualboot avec Windows 10. Toutefois, je rencontre quelques problèmes de connexions Wifi. En effet, Ubuntu reconnaît bien ma connexion Wifi mais il semble y avoir des problèmes de lenteur comparé à Windows 10. De plus la commande iwconfig m'indique "no wireless extension".
Voici également quelques résultats de mon wificheck :
>> sudo iwconfig
wlo1 no wireless extensions.
3
enp3s0 no wireless extensions.
lo no wireless extensions.
>> cat /etc/lsb-release
